QRP on the bike
- Hi everybody!
Today I just had fun while riding my bike. It was nice to have a walk in Bordeaux and then standing in front of the city getting many QSO with my MP1 superantennas and my loyal Elecraft KX3. It was a nice to do QRP on the bike.
Together with my bike, the Trek FX 7.2, I drove out of the city center. I stopped there, on the waterfront, laying the bike just on the wall and then I deployed the MP1. My MP1 superantennas is a modified QRP antenna: I changed the top whip with the one from buddipole. I increased so far the length of the whip by 1 meter. Not so bad. (see photo).
The Solar flux was 108 while the K factor was 3. Very bad propagation settings.
But… together with my QRP Elecraft KX3 and 5 watts… I had chance to get:
- S5SR on 30 meters band (10.115 MhZ) who gave me a 599 report in CW
- UA3HRP on 15 meters band (21.224 Mhz) with RS of 57 (USB)
- DF2OB on 20 meters band (14.310 Mhz) with RS of 58 (USB).
- IZ8FFC on 17 meters band (18.130 mhz) with RS of 57 (USB).
- SV9GLL on 20 meters band (14.219 mhz) with RS of 59+10 (USB).
My general recommendation if you like to do QRP on the bike is to use a mountain bike – and to get with you a MP1 supernantennas. Another option could be to get a dipole or the famous alexloop antenna. The End fed antenna is the best option because is easy to transport. The best ham radio setup I believe is represented by the YAESU FT 817 ND because of the rugged construction. Elecraft KX3 has the ATU enclosed but is not a rock like the ICOM 703 or FT 817.
I really enjoyed going QRP on the bike. Please see down here the VIDEO (click on the arrow)
HF antenna Outback 2000 – Full review
(tested with an Elecraft KX3 SDR Transceiver)
When I first thought of that I smiled. How you can associate a 79$, coiled, fiberglassed, vehicular antenna and a 1200$ SDR transceiver HF radio?
The outback 2000 is a “copy” of the most famous outbacker antenna (used in Australia to cover many miles in HF by doctors and normal users – to communicate important news). The outback antenna is a fiberglass mast (magnetic support NOT included) where performances are insured by the “wander lead” that is coiled around the “mast” of the antenna. There is a banana plug where you can easily tune to 40 meters (2nd hole) 30 meters (3rd hole) 20 meters (4th hole) 17 meters (5th hole) 15 meters (6th hole) 12 meters (7th hole) 10 meters (8th hole) and 6 meters (last hole). At the top there is also a short whip that allows you to fine tune the antenna for each band.
Total lenght is 1.75 meters. It covers every band and you are allowed to transmit up to 200 W.
I have an Audi A3 and during weekend I love to get outside my city (Bordeaux). I reached 110 km/h without no problems for my outback antenna.
I had a QSO while driving to Dordogne with an Italian friend IZ8FFC Giuseppe in Crotone (KR). He gave me a 59 report with excellent modulation. Frequency was 14.310 MhZ and my ROS was 1.6. I didn’t want to tune the OUTBACK 2000 with the KX3 autotuner. The result was excellent: I was able to cover 40 to 10 meters with max 1.8 ROS (on 40 meters band). The only issue as you can immagine was to get out of the car everytime to decide on which band to transmit. Simply plug and play.
Best resonance and performance was on 20 / 15/ 10 meters band.
The outback 2000 Falcon is definitely a good compromise. I would rate the antenna as 8.5 on 10! The price is excellent and you can get one used on eBay for few bucks. You will be on air 80/40/30/20/17/15/12/11/10/6/m in few seconds.
The only cons I can notice is the high QRM and this won’t let you to copy weak stations. Especially USB mode.
If youwant to increase the potentiality of this HF antenna, go closeby the sea. It would be much better.
After 1 month of test I had more than 80 QSOs. In my logbook I had chance to add Turkey, Ireland and Ukraine.

Software defined radio LNR transceiver FX-4a *REVIEW*
I’ve tested for you the FX 4a transceiver. This is an excellent Software defined radio
Hereby a little review for you.
This new transceiver has been released few months ago and replaces the original Software defined radio FX-4 that was introduced in 2013. It’s quite impressive as transceiver because very light (345 gr) and tiny (dimensions: 4 in length x 2.8 width x 1.5 thickness).
Ah yes, it arrived to me fully assembled (what a shame! – I LOVE TO BUILD my TRANSCEIVER!) – so no kit! The radio was delivered in a double carton and extremely well packed. 1 week to arrive to Europe.
This Software defined radio covers HF but only 4 bands (40 meters , 30 meters , 20 meters and 17 meters band)
True QRP: only 5W. Modes are SSB and CW.
Selectivity is quite sharp while calibration is excellent.
In reception I found the LNR transceiver FX-4a as an excellent SDR receiver: audio is clean and pleasant but AGC action is of low authority. Compared to my Elecraft KX3 signals were loud and more clean. Consider that on my KX3 I have installed the roof one.
Specifications of this Software defined radio LX4
- Push to Talk Speaker Mic
- VFO A/VFO B
- LSB/USB/CWA/CWB Modes
- Input Voltage Monitoring
- RIT Functions
- Independent Side Tone
- Iambic Keyer
- CW Call Feature
- 5W Output
- 10 Memory Storage per band
- Microphone and Power Cord included!
- 90 Day Warranty
Comparison with the FT 817 ND
I found the FT 817 more silent and I have to say the LNR FX-4a as more sensitive.
Dimensions are clearly in favor of the LNR transceiver. Please see down here the comparison:
The Software defined radio SDR FX-4a is half size and also lighter than Yaesu FT 817. Also you may consider battery that are not included in the LNR precision transceiver. I suggest you to get a LIPO from RC model store like I did (3S 13.8V 2100 mAh for few bucks). I always like (and I will like) the audio from the speaker of my YAESU FT 817 ND because it’s louder than these two SDRs (Elecraft KX3 and LNR FX-4a). Reception : LNR FX-4a was clear and nice to hear but FT 817 was not so bad. I tried these two with a random wire antenna tossed into the tree in front of my house. I should maybe have tried this (LNR precision end-fed antenna)
Price is around 450$ (not so much).

Review of the Gipsy dipole
Windcamp Gipsy Portable HF Dipole
Brad Kathrins – W8PAL
In May of this year, I picked up a very clean, used, Yaesu FT-817. This was my first QRP rig and I was excited to get it on the air. Now let me first give you the disclaimers. I have been a ham for 20+ years and a General for over 10. I live in an antenna-restricted neighborhood in Glendale, Arizona (DM33vq) so my HF activities have been sparse and limited to a multi-band dipole stapled to a roof eave. The performance of which is about what you would expect. I have logged very little HF activity. Additionally, my experience with QRP was somewhere firmly between “slim” and “none”. I was a QRP n00b, if I am using my son, KG7ERI’s terminology correctly.
Knowing that I was going on a family vacation visit my in-laws in Indiana (EN70fu) in a few weeks, I decided I needed a portable antenna, or antennas, to bring with me. Yes, I get along very well with my in-laws and was glad to be going. We always have a great time when we visit. In fact, I’m very close to convincing my father-in-law to get his ticket as well! After spending time reading reviews online and talking to the FT-817 Facebook group, I purchased two antennas: a Buddistick vertical and Windcamp Gipsy Portable Dipole. This review is on the Gipsy (sometimes spelled ‘Gypsy’, depending on the website).
I first saw the Gipsy at Hamvention. One of the indoor vendors, Hamsource (www.hamsource.com) had it for sale.
I almost bought it then, but after my FT-817 “impulse purchase”, I really didn’t have the available funds. Now that I had a few bucks built back up, I threw the bone to Hamsource and ordered the antenna. For $70, it seemed like an interesting solution.
The antenna arrived in a very small, somewhat square box. I opened the box and pulled out an olive drab, drawstring, canvas bag that was only slightly larger than my fist and tipped the scales at 14 ounces. I shudder to describe any of my technical possessions as “cute”, but there was no denying that the little bag was just that. Inside the bag was a 1:1 balun, two spools of antenna wire on metal winders, an extra drawstring balun hanger cord and an instruction card which was, helpfully, written in Chinese. The Hamsource website did have the translated version of the instructions available for download.
The antenna wire is made of teflon-coated, 20AWG copper that is quite durable. The winders are metal and appear to be either anodized or powder-coated black. The balun is sealed and is black with what looks like a carbon fiber checkered body with black metal caps. The only thing that is plastic on the entire antenna are the nuts used to secure the wires to the balun posts.
The Gipsy is rated to 100 watts PEP and tunes from 40m through 10m. The method of deployment is painfully simple. You connect the ends of the wire spools to the balun and simply unroll the spools to the length of the desired frequency. The wire left wound on the spool is “electrically ignored.” It can theoretically tune from 7-30 MHz continuously, depending on how much you have unrolled.
At several points along the wire, there are color coded pieces of shrink tubing that correspond to the following frequencies:
Red – 28-29 MHz
Clear – 24 MHz
Blue – 21 MHz
Black – 18 MHz
Yellow – 14 MHz
White – 10 MHz
Green – 7 MHz
I was going to have a “cheat sheet” laminated to remind me of the color codes until I noticed that they were very cleverly silk screened right on the winders! The directions indicate that the antenna can be setup as a standard flat-topped dipole, an inverted “V” or sloper.
My in-laws live outside of Huntington, a small town in Indiana about 30 minutes south-southwest of Fort Wayne. Their property is in an elevated, wooded area south of the Wabash River, with very little around except for trees and a stocked fish pond. I brough three rolls of paracord and threw a weighted end of each over a branch in three separate trees that ran in a line roughly south-southeast to north-northwest, giving me a clear shot to the west-southwest and east-northeast. The distance between the outside trees was further than the length of the dipole set to 40m. I tied the center paracord to the balun and hauled it up about 25 feet. I “set” the frequency by adjusting the length of the wires to the correct length then running them through the lock notches in the winders. I chose 20m since this has been the most active band. I then hauled the winders up into the outside trees until the wires were taught and in line with the balun. I tied off the paracord lines so that the winders could be lowered, the wires unrolled or rolled to change frequency, then hauled back up into place. This also came in handy mid-week when a squall line headed our direction like a runaway locomotive. I was able to lower the antenna and pack it up in a few short minutes, leaving the paracords in the trees to haul it back up after the storm.
Due to a very active week, thunderstorm-wise, the background noise level was elevated for most of the week. This was on both the Buddistick and the Gipsy. Most times it was between S5 and S8, but there were those rare times when it dropped to an S3. Indiana has had significant storms and flooding this summer and the crops have suffered for it. I saw many farmers’ fields that were totally flooded out and the corn was pitifully short.
Before hauling the balun up the tree, I connected a 75′ length of RG-8X as my feed line. I used an MFJ-223 antenna analyzer and the antenna showed an SWR of 1.4:1 on 14.270 MHz. I have no doubt that if I were to brave the mosquito swarm outside and played around with the length of the wires a bit, I could have brought that down even more.
I did a head to head comparison between the Buddistick and the Gipsy. I realize that they are totally different animals and each will serve me well in different applications. That said, the Gipsy was less noisy than the Buddistick, drew in weaker signals (by at least one or two S units) and took up far less space when broken down and placed in my luggage. The set-up of the Gipsy required some fancy line tossing – a slingshot line thrower would have been nice, but it was with far less tweaking than what was required to get the Buddistick tuned.
I tried the Gipsy on 40m, 20m, 17m and 10m, but 20m seemed to be the most consistent from a band condition standpoint.
I would have liked to say that I filled my log with contacts but that just wasn’t the case. Some of this was due to the noise, some was due to family activities encroaching on prime “hamming” time. I’ll admit that much of it was due to me being a QRP n00b and trying silly things like answering a DX station calling CQ with a pile-up of QRO operators trying to get back to him. Live and learn.
I was hoping to have a QSO with my friend KG7YC back home in Phoenix. We tried several times and, while he could hear my voice and knew that I was talking, I wasn’t quite making the trip with only 5 watts. I did finally talk to KB5YN in Waco, TX on 14.235 MHz.
I am very pleased with this antenna. It is compact, durable, easy to set up, and seems to perform well. It’s great for Field Day, camping trips or any other temporary setup. It survived some windy conditions and some rain with no ill effects. It can literally be thrown into your suitcase and will take up less space than a rolled-up t-shirt. Once I improve my QRP technique, I expect to make many contacts with this “cute” little bag of antenna.

Maximizing battery life of Elecraft KX3 QRP
Battery life can be improved by minimizing the KX3’s receive and
transmit current drain.
The KX3 already has far lower receive-mode current drain than most all-
band/all-mode transceivers, but you can further reduce it in several
– use headphones (10-100 mA saved depending on volume level)
– turn off the LCD backlight (25 mA)
– turn off the RX I/Q port when not needed (10 mA; see MENU:RX I/Q)
– turn off the preamp (5 mA saved for the 20 dB preamp,
10-15 mA for the 10-dB preamp)
– turn off the RX isolation amp (10-15 mA; see MENU:RX ISO)
Using all of the above techniques, receive-mode current drain can be
as low as 150 mA, varying a bit per-band.
In transmit mode, current drain varies with power level, supply
voltage, band, and load impedance. An antenna tuner (such as the
internal KXAT3 option) can help ensure the transmitter sees a good
There are some thresholds where the transmit current drain is
automatically reduced by switching in a higher-impedance PA output
transformer winding. In this case a decimal point is added to the
right of the power display when you adjust it (e.g., “3.0 W.”). Here
are the conditions under which TX current is reduced:
1. 5.0 W or less in CW, FSK-D, and FM modes when key-down supply
voltage is 11 V or higher
TX current in this case is typically 1 amp — about 50% lower than
what you’ll see if you move power just a bit above 5.0 W. This is
especially useful for QRP Field Day outings (etc.) where the rig is
powered from an external 12 to 14 V battery.
2. 3.0 W or less in all modes, regardless of supply voltage
This is the generally recommended power level when operating from an
internal NiMH battery pack. If you’re more interested in power output
than operating time, you can run up to 5 watts from the internal
Elecraft KX3 SDR transceiver
A QRP Qso with only 2 watts
I was just testing my new Elecraft KX3 SDR transceiver. Here you have my own video while having a QSO in QRP 2 watts only. What do you think? Perfect CW decode also, uh?
My setup is:
Elecraft KX3, MP1 superantennas on the balcony rail and just 2 watts.
(Best) Travel QRP HF antennas
1) Alex loop antenna.
Who doesn’t know the alexloop antenna? This is the best solution you can have. QRP Travel antenna per antonomasia.
This magnetic loop antenna has been designed by Alexandre Grimberg PY1AHD from Brazil. (AlexLoop.com if you wanna buy one). The AlexLoop implements a mag loop for the 40 through 10 meter bands. When packed into a small bag that comes with the purchase is perfect for Rapid Deployment Amateur Radio (RaDAR). You can use a tripod or any other stuff to use this great antenna inside the room of an hotel or, better, while camping on the seaside…Click down here to see
- Multiband: This loop operates 7 through 30 MHz. Go from 20 to 10 meters band is really fast as it just requires adjusting the tuning capacitor.
- Tuner: Not required !
- Efficiency: every ham that has used this antenna is enthusiastic. 90% of efficiency I’d say.
- Easy to transport!Cons
- Bandwidth: Narrow! This is the price you pay. It does require retuning when moving up and down the band or changing bands.
2) Radio Shack “reel” antennas
I have used these YO-YO Radio Shack “reel” antennas for “camping” / bungalow holidays in Greece or South Italy. These consist of a 10 meters thin wire that is reeled up in a plastic case. This little tiny compact antenna is easy to transport and useful to get you on air on 30 meters band. You can connect one wire to the center of a coax connector and put an alligator clip on the other. The alligator clip can easily be connected to the shield of the coax connector or can be clipped to the SWL portable antenna. (see photo). I can promise you this is the cheapest and easy solution. You will enjoy. Some tips:
- The angle between the wires isn’t very critical. Just adjust the shorter wire length and position a little to get a match.
- The exact orientation of the wires isn’t very critical, either. Droop one over a balcony, hang the end from the curtains, etc. The antenna is somewhat directional broadside to the plane of the wires.
If you are looking for a well-made and easy antenna for field use, you aren’t going to beat this one. And the price is more than reasonable.It is definitely a quick and truly portable setup! A must have!
This tiny antenna (less then 1 meter in length) attaches directly to the back of your QRP rigs (except Elecraft KX3) but it would be perfect for your yaesu FT 817 transceiver. It has a built-in tuning device. Using this whip, sitting on the table of your hotel (using at least 10 foot radial running around you) you may be able to connect the world! The best would be to transmit in CW or PSK31. I have no complaints about this nifty little device. It will never replace a Mosley 3 element beam but what it does do, it does it very well indeed. The Miracle Ducker TL works very well on 20-10 meters, with a good counterpoise. I suggest the use coupled with Yaesu FT 817 on 15 – 17 – 10 meters band!
You can always get an used one for few bucks on eBay!
Wonderwand loop antenna
This could be interpreted like a miracle whip antenna but it isn’t. It is a miniaturized loop antenna. Tuning from 20 meters to 10 meters band. Excellent in receiving. I would say 10/10 ! We already talked about this great tiny antenna here. Ideal antenna for portable operation. Little space required, compact and it works. Compared to other portable antennas the noise margin is down by a lot. I actually do get contacts on 5 Watts consistently.
The wire which comes with the wonderloop for the self supporting loop is very sturdy and good for the job. Tuning is very precise due to the high Q of the antenna so a slow, steady hand is needed to get the SWR for a particular frequency down to 1:1 – 1:1.5 typically. When you move more than a few KHz from a tuned frequency, another adjustment is necessary.

Elecraft kx3 transceiver tips, mods & hints
1st TIP: How to save battery power.
Use 5.0 watts or less when running from a 12-V source, and 3.0 watts or less when running from an 8-10 V source (including the 8x AA batteries). At these levels, the elecraft KX3 transceiver automatically switches the power amplifier to a more efficient setting. You can tell that power-saving mode is in effect by a decimal point after the ‘W’ in the power value (e.g., “5.0 W.”). Why not to use headphones rather than the internal speaker? You can save other precious mAh during reception (around 80 mAh) and , also, if you can …turn off the LCD backlight (Menu: BKLIGHT). The current drain of the Elecraft KX3 is around 1.20 Amps on transmit with 5 watts out. See the video clicking on the arrow down

elecraft k3, price, sell, craigslist, eBay,
2nd TIP. Isolate the oscillator.The elecraft KX3 transceiver, like other radios with a quadrature direct-conversion architecture, uses a VFO (local oscillator) running at or very close to the operating frequency. If you have another radio on the same band as the KX3, and the antennas are close together, the other radio may be able to hear the KX3’s oscillator when they’re both tuned to the same frequency.To prevent this, the KX3 includes an isolation amplifier that keeps the oscillator from radiating back through the mixer. Normally this amplifier is turned off to save about 15 mA of receive-mode current drain. To turn on the isolation amp, set MENU:RX ISO to ON. This has no effect on performance.
3rd tip: going portable? Get a lipo for your Elecraft KX3 transceiver
There are many kind of LiPo batteries and these are a great addition to my elecraft KX3 transceiver package. A fully charged 3S LiPo battery is around 12.6 volts. You can use your QRP KX3 @ 10 watts output power with this battery for the entire afternoon! Down here there is a nice video on operating tips (Elecraft KX3 transceiver) click on the arrow!!!
To do this, simply tap ATU TUNE a second time within 5 seconds of the first match attempt.
In his case, a 1.0:1 match was found on the second try.Clearing out old LC data. The KX3 stores ATU LC data for many segments on each band. The LC data required to match a home antenna system is often quite different from what is needed to match a field antenna. So when operating in the field, you may find that clearing all of the LC data for each band used can save a lot of re-tuning time. This is done by locating the ATU MD menu entry, then holding CLR (a switch function of the RIT offset control). Then exit the menu.
The ATU will use the LC data from the closest segment that you’ve tuned, so when setting up a new antenna, you can tune up in as little as one spot (if the antenna is broadband) or as often as within every segment. Segments are on 20-kHz boundaries on most bands (5 kHz on 160 m).
Elecraft KX3 software
The KX3 version of Win4K3Suite provides full control of the KX3 as well as a sound card based Spectrum Scope displaying KX3 signals in real time. Full support for point and click frequency changes for both VFO’s. Unlike many Software Defined Radio software, all demodulation, modulation and filtering of the KX3 signals are handled by the KX3 itself. This “Hybrid SDR” approach leaves the digital signal processing to the engineers at Elecraft, while providing a full featured spectrum scope like the P3 and full control of the radio. All other features of Win4K3Suite are included.
Elecraft companion (shareware)
Simple app (less than 5 euro only on ANDROID market) that will let you send and receive CW, PSK31 and RTTY by using your tablet. You can set up to 10 macros to that can use dynamic symbols to have Call, Name, QTH and Locator automatically updated.
You need only the standard USB Serial cable that comes with the radio and inexpensive OTG Cable adapter to connect the serial USB to your mobile device. You can find them for 10 bucks on eBay.
Recently has been added a NEW FEATURE: Audio Spectrum and Waterfall! Selecting the “SPECTRUM” tool, the app shows the audio spectrum. For devices allowing that, you can also attach the KX3 Audio OUT to the device Audio IN for a better signal. The spectrum shows the DSP filter center frequency and its bandwidth. By touching the spectrum you can also see the shift and frequency of every single line. You can zoom in and out to have larger spectrum bandwidth.
