The complete review of XIEGU X5105

The complete review of XIEGU X5105

The complete review of XIEGU X5105

Here, there is. We have the Xiegu X5105 – Full review down here.
After 7 months of long waiting we have commercially available since September 1st, the XIEGU X5105: the last HF+50 mhz TRANSCEIVER from this chinese, but high quality, company.
We have reviewed it for first thanks to Stephen (Xiegu) who has recognized this website as reference for many ham radio operateurs. The package was well made (See video) and in only 4 days arrived home. Honk Kong to Bordeaux, France. Wow.

The box contained 1) the xiegu x5105   2) a power cord   3) the microphone and his cable.  4) instructions, warranty 1 year and some adhesive from XIEGU.

The xiegu x5105 weights only 550 grams and when compared to the Elecraft KX3 it looks smaller (2 cm less in length). X5105’s LCD is brighter than KX3 and this is more like a box. The LCD, when you turn it on, shows a “welcome” from the XIEGU company.  When the X5105 is on you can clearly see on the display: VFO-A (B) , Mode (CW, CW-R, USB, LSB, NFM, AM), Power in % (100, when it arrives to you:-) ) FREQUENCY in big capital cyphre, then S-METER, VOLUME, Pre-amplication option /yes or no, AGC, Filter.

On the botton of the LCD there is the MENU.

The xiegu X5105 performs very well on HF bands. Unfortunately I didn’t have chance to test it on every band due to no good propagation. I had chance to make some QSO in 30 and 20 meters with SM (Sweden), SV (Greece) and E (spain). USB modulation has been reported as “excellent”.
Soon I will add some audio in regards of this modulation. Speech could be improved within the menu: compression ON.

Accessing the menu is quite easy: there is a MENU button, at the bottom right of the panel. There are several options you can access to: Noise reduction, Noise blanking, Filtering, Notch, AGC, Memories, KEY (CW), Recording messages (up to 3). Last page of the menu is the info, and version of the XIEGU X5105 software.

COMPARING the XIEGU X5105 to ELECRAFT KX3

We compared the two transceivers. Check it out by yourself which one is the smaller (we will tell you which one is the lighter!).

Yes, the XIEGU X5105 wins. And it’s also lighter! 120 grams less!

When you connect it to the socket and leave it in charge, the LCD will show you mAh of your battery and how much charge there is. Good for monitoring your internal battery pack when powered off and on charge.

Charging and maintenance of internal battery
X5105 has a built-in 5000mAh battery pack. When the external power supply is not connected, the battery pack supplies power to the X5105, when the X5105 is connected with an external power supply, the circuit inside the machine automatically switches to the external power supply.

In few words:
ALL BANDS COVERING: With a built-in power output of 5W, Xiegu X5105 is a highly portable transceiver working at HF+6m band, covering all modes of HF, 50MHz band (SSB/CW/AM/FM/RTTY/PSK).
LCD: Xiegu X5105 is equipped with a 3.6 inch large LCD screen and built-in 3800mAh large capacity battery pack. Besides, it also comes with a trestle for desktop operation.
IF OUTPUT: With IF signal output (1 IF: 70.455MHz, 2 IF: 10.695MHz, 3 IF 455kHz (FM)).

XIEGU X5105 Photos LEAKED

Hello every HAM RADIO Enthusiast,

It looks like some photos of the UPCOMING XIEGU HF TRANSCEIVER (5105 model) have been leaked. We received these photos from the East part of the world.

Briefly the X5105 model, produced from this promising Chinese Company (XIEGU) is a highly portable, reliable,  HF transceiver working the HF plus 6m band. Built-in power output of 5W.
On these leaked pre-production photos, seems there will be a ATU (automatic antenna tuner) which is great. Weight should be only 750 grams and it looks to be very transportable. Rugged construction.

Technical features: double-conversion superheterodyne, fitted with up to 3 lithium batteries of 18,6 Amperes each.

As you see the 5000mAh battery pack is removable.

Inside the PCBs

Front panel.

These are the leaked photos of XIEGU X5105 model.
Looking forward to have it in our hands for a review.
Definitely is the most interesting product of 2017.

Cost around 450$? Expected to be released in August 2017.

Now available. This is a QRP 5 watts only HF transceiver 0 – 30 Mhz. It’s an open source Portable HF SDR Transceiver made by Mike Colton (KE7HIA). Named the PSDR. Ah, I forget: it has also 144 MHz band. The transceiver base his force on the CPU ARM 168MHz, colour display, and an innovative interface. Vector Network Analysis (which includes antenna analysis) and GPS functions are included.

The PSDR radio recently won 3rd place in the 2014 International Hack a Day prize competition and has now launched over on the Kickstarter crowdfunding website with the aim of raising $60,000 to make the jump into manufacture.

PSDR transceiver - Ready to be Assembled
PSDR transceiver – Ready to be Assembled

Michael colton in his last interview, declared: I’m an avid backpacker and radio enthusiast. To me there is something exciting about making contact with others from remote locations where cell phones and the internet can’t reach. I wanted an advanced radio that was ideally suited to tough environments.

That meant I it needed to be very compact, integrated, and durable. As an engineer, I wanted an open platform that really takes advantage of the hardware and has the potential to grow and be used for other applications.

There are numerous, excellent radios out there, but none offered the combination I wanted. The best radios are closed source, larger, and expensive, while most open designs are very basic and lacking in flexibility.”

… soon available. 

Available on the market since next Spring. Be aware this is a “beta version” with only few milliwatts as output. Speakers, not functionally working. Next step, Michael said, will be to increase power up to 4 watts at least.  Click down here on the arrow to see a full complete review on PSDR HF transceiver 🙂

Yaesu FT 817 on the citizen band
How does it perform?

Hello everyone.
This is a post just to tell you how well is performing my 5 watts transceiver Yaesu FT 817 on the citizen band.

On the AM side it works fairy well. 5 watts in AM are enough to have QSO around 30 miles especially if you have a omnidirectional antenna. I had different QSO with other real CB people, here in Italy and they give me back good reports.
The original microphone has good quality and output is loud and enough clear to stand out a communication with the other side.

The other possible option is to go on the “upper side” bands 27.555 MhZ (USB). As you may know this is the main calling frequency amongst 11 meters lovers band. Look at this image:

2012-10-13 20.05.09

It’s our Yaesu FT 817 ND with the miracle whip antenna! I had several contact with this QRP radio transceiver on 11 meters. Many QSO with every country of Europe: longest QSO was 4928 miles (European asia). It was on 27.530 Mhz USB mode. I also tried this on CW mode (27.500 MhZ) having a contact with one AT member of Sevilla (Spain). I can say that this DUO (Yaesu FT 817 ND and Miracle whip) is great. Excellent job I would say.

If you’ll use the FT 817 ND at home, we strongly suggest you a easy deployable dipole 5.5 meters per side. It will be easy to toss into a tree. No manutenction needed and … cheap! Last option could be a MP1 superantenna. Easy to install everywhere. (110$).

Naturally if you want to operate with the Yaesu FT 817 on the citizen band you have to perform the MARS modification to open to transmission on the CB frequencies. Many users has reported that it doesn’t like to transmit outside of its factory specifications at full power.

ft-817_filter
Yaesu FT 817 on citizen band – SSB COLLINS filter

I believe that YEASU FT 817 on the citizen band is excellent from the receiver side and is probably much better than most CBs, especially in SSB mode with the optional Collins mechanical filter. (See below)

And you? Are you using the Yaesu FT 817 on the Citizen band?
Can you please share your thoughts about this? What setup do you have? Can you upload the photo of your shack?

I would like to share with you this great video (it’s not me) but…is one of the most clicked video on the topic Yaesu FT 817 on the citizen band.   CLICK DOWN HERE ON THE ARROW If you also like this page, and you’re interested in build up a YAESU FT 817 27.555 mhz fan group, let us know!

Best QRP transceiver kit

Best QRP transceiver kit

Best QRP transceiver kit

Hendricks QRP radio
BITx – two version 20A (14 mhz) and 17A (18 mhz)
Score: 7/10

Bitx20A – 14 mhz (20 meters band) transceiver by Hendricks radio

The BitX20A and BitX17A are complete SSB kits with board, all parts, digital display and custom powder coated and punched case that is based on the BitX20 that was designed by Ashlan Farhan (VU3ICQ). The kit includes a commercial quality plated through, silkscreened, solder masked board, and all board mounted parts, plus the polyvaricon tuning capacitor, digital dial, custom powder coated and punched case, knobs and controls. Everything you need to build the kit is provided.The original design produces six watts of SSB on twenty metres and is based on a common bi-directional amplifier block using cheap NPN transistors. The radio also uses a filter using cheap crystals and mixing is done with 1N4148 diode.The current project is based on the new version produced by Henricks QRP Kits of Dos Palos, California. Known as the BIT20A, the kit is based on a professional PCB, has push-pull output and a number of other enhancements. As of October 9th, 2007, the first batch of 200 kits are being dispatched around the world. These transceiver kit represent a real bargain.

Receiver: 9. Not noisy at all. Decent single conversion receiver.
Portable: 3. Poor. No battery enclosure
Power: around 5 watts basing on our test @13.8 V

KD1JV
Tribander CW transceiver qrp kit
(Any three ham bands, 80, 40, 30, 20, 17 or 15 meters)
Score 7.5/10

KD1JV tribander CW transceiver kit

  • 5 watts output on all bands with 13.8V supply
  • Built in Iambic keyer with 5 to 40 wpm code speed, selectable Iambic A or B modes and two 63 character message memories.
  • Receiver sensitivity, 0.2 uV MSD
  • DDS VFO for rock steady stability with 50 Hz and 200 Hz tuning rates
  • Easy to read four digit LED display with leading zero suppression.
  • Rotary knob tuning
  • RIT (receive incremental tuning)
  • Four IF crystals for excellent selectivity and opposite side band rejection

Receiver: 8.5 – Decent single conversion. No QRM at all. Excellent work by IF crystals. Especially on 20 meters.
Portable: 5. Small size, 6″ wide, 1.5″ tall and 4″ deep. 12 ounces (light weight)
Power. 8 – 5 watts out. 90 mA on receive and 800 mA when on air
Small wonder labs
CW or PSK 40, 30, 20 meters kit
Score 8.5 / 10  

Small wonder lab rockmite

 It is a capable single band, DDS-synthesized, superhet, 2W transceiver. It has a built-in PIC-based keyer, and the PIC provides a number of other functions in controlling the rig. You have an audio frequency readout, in CW; a really nice RIT; two tuning rates that really do the job-using an optical encoder; and an extended frequency range on receive, covering pretty much the entire 40M band and some beyond. DSWs are currently available for 40M, 30M, and 20M. All HF bands are planned. At about $90 for the basic pc board and parts, and another $35 for the cabinet, it’s incredible. And that striking blue cabinet with engraved front and rear panel legends makes the cabinet practically a necessity! Total construction time was 1 day. Nice and easy construction. What we like is that is very small and with low power consumption (only 32 mAh). That’s great! This QRP radio kit is capable of putting out 2.5 watts with adjustable power  ( 1 watt up to 2.5 watts).

  •  Single-board transceiver, 2.8 x 4.0″ (7 x 10.1 cm)
  •  True VFO: 35-40 kHz coverage
  •  Superheterodyne design, with crystal filtering
  •  Quiet solid-state T-R switching (QSK)

Receiver 8. Excellent radio kit. Good built with true VFO and no QRM.
Portable
10. Outstanding. In a tuna tin it will be perfect.
Power 7.  Two watts are okay for us – it’s a QRP and we love QRP for this reason but 5 watts would be perfect.

SDR Cube transceiver kit
1-30 mhz transceiver
Score 7/10

SDR Cube – transceiver
 The SDR Cube is a totally self-contained, embedded best SDR all mode transceiver (CW, SSB, AM) . It uses a Softrock for the RF front end and a pc board implementation of an HF modem.  You don’t need a PC / MAC to use the SDR Cube, as all DSP processing is accomplished by an embedded DSP processor on the three internal pc boards.  The Cube is designed to fit into an optional 4” x 4” x 4.5” pre-cut,black powder-coated aluminum enclosure containing all controls, a blue graphic display indicating transceiver settings and an exciting 8 kHz-wide band scope of spectrum signals, and the popular Softrock RXTX v6.3 board.
What we liked:
 Low Power … 90ma (Cube), plus 100 ma (Softrock Rx) or 400 ma (Software Tx)
 Graphic LCD Display … Provides clear indications of the many status and options
 Bandscope … Provides +/- 4 kHz spectrum visibility for Rx, signal monitor for Tx
 Audio filtering … Low corner 200Hz, high corners 700, 1500, 2400 or 3600Hz
Receiver: 9. Excellent receiver. No problem to copy long distance signals.
Portable: 3.5. Not very easy to transport.
Power: 8 – Low power adsorption. Only 120 mA.

Elecraft KX3 review

Elecraft KX3 review

Elecraft KX3 review

It was the 2011 when Elecraft company (an US based company, very rare phenomena) introduced the KX3 model.
A real jewelry : portable SDR HF plus 50 MHZ transceiver.

It includes every mode you need: USB, LSB, CW, data, AM and FM.
The output power is adjustable from 0 to 10 Watts. You can easily adjust the DSP filters, AF, RF, passband, and notch all from dedicated buttons and knobs. It even has a memory keyers for both CW and voice.

Wanna do digital modes? No problem!
The KX3 natively decode RTTY and PSK31 and display the scrolling text on the display, but you can also send RTTY and PSK31 without a PC. How? Simply set the appropriate data mode and use your key to tap out your message in CW.

DSP filtering is most impressive.:  have a look at Sherwood Engineering’s receiver test data rankings which are sorted by third-order dynamic range (narrow spacing), the Elecraft KX3 is second only to the Hilberling PT-8000A, an $ 21,000 transceiver.

QRP with Elecraft KX3

When I decided to go in QRP with my Kx-3 this little QRP performed very well. The very low current draw allowed me to use full power (approx 10W) using a Lipo battery (Turnigy 2200mAh 3S 20C Li-Po 11.1v) that lasted for at least an hour before turning back the wattage (to 5W) when the battery voltage dipped below the 11vdc threshold (time will vary depending on duty, temp and mode).  The radio is easy to pack and deploy. If there are trees tall enough in the area, I can hang a dipole and get on the air within 10-15 minutes.

You can also use 8x AA batteries (see photo above) but these are not great in performance like the LIPO!

PRICE
Being that the non-solder kit version of the KX3 is $899.95 and the assembled version is $999.95, I really do not consider this a bargain at all.

X1M Pro Platinum QRP Transceiver

X1M Pro Platinum QRP Transceiver

X1M Pro Platinum QRP Transceiver

DXing with this small qrp transceiver is a great pleasure. The X-1M is the new compact HF transceiver from CHINA. It’s a very light qrp radio (750 gr) suitable for the back packers.

Here our unboxing and review!

Specifications of X1M Pro Platinum QRP Transceiver

– Manufactured by Chonqinq Xiegu Technology Co., Ltd. of China.
– Frequency range RX:  0.1 ~ 30 MHz
– Modes: USB & LSB & CW
– Power output: 5 Watts
– Rx Preamplifier
– Automatic Internal CW Keyer
– CAT Control:  Compatible with Ham Radio Deluxe

  • Receiving sensitivity: better than 0.45uV,
  • RF output power: ≥ 4.5W
  • Frequency stability: better than 0.5ppm
  • Frequency accuracy: better than 0.5ppm
  • Operating voltage: 12.0 ~ 14.0V DC
  • Receiver Standby Current: 0.5A
  • Emission current: 1.5A Max

The X1M Pro Platinum QRP Transceiver has an improved display, controls, quality of components and filters.

There is also a recent new version called X1 MKII which is 20 watts! Color Display with 50MHz and IF-DSP – receiver triple conversion. Preliminary features: RX: 0.5~30M,50~55M – TX:0.5~30M,50~55M – SSB/CW/NFM/AM/RTTY – TX 20W output – Power 9~20VDC (0.42A @Min – 4.5A @Max).

The green display is easy to read as is all the silk screening on the front and rear covers. The audio from the unit is also very clean and loud for a small unit. The unit is very light for an all band and all mode unit. Preamp works well and unit is very quiet on receive. Menu navigation is easy.

The microphone is small but comments received on SSB are that the microphone is very hot or sensitive and the radio can be overdriven if talking too loud or too close to the microphone.

Both USB and LSB work well on receive and even when shortwave listening it sounds great when tuning an AM station once you get used to it.

The memories are nice if you wish to program your favorite calling frequency or shortwave station. You cannot however use the memories and then tune the vfo from them; you have to go to VFO mode if you want to change frequency as the memories are locked as just that.
Click on the arrow at the end of this article to see the video on how this QRP transceiver kit performs in reception / transmission and compare this with the FT 817

PRO
Light QRP radio
SSB/Am/Fm/Cw – Micro included
Display quite large

CONS
The AGC could be better as a strong local signal will overload the front end.
There is no S-Meter and no power output signal meter.
Price ! (Still over 499$) for a chinese HF radio.
If you connect the X1M Pro Platinum QRP Transceiver accidentally into an antenna with > 2:1 SWR the PA transistor is liable to blow

PSK31 and RTTY via wolphilink interface
Article by W4FDT

Original article here

“You can do very efficient PSK31 and RTTY among other things with a device called Wolphi Link and the
droid psk app in the android play store. The device can be purchased through the wolphilink website:

It is very simple to hook up, infact it just plugs into your tablets headphone jack and the other end plugs into your data port on your radio and thats it. No software to adjust, no sound card drivers to fool with or anything like that.

Here there is a video of me using it with my current setup.

Attached is a picture of the way my setup is done and it is very convenient for me. Portable ops cannot be much easier without having to haul around a laptop etc to run digital modes, i can just use my regular cell phone!”

Alexloop HF antenna review – cost, considerations and tips

Here you find PY1AHD describing and introducing us his great antenna that I personally tested with my two QRPs ( Icom 703 and Yaesu FT 817 ND).  What can we say on this loop antenna? Only one word: excellent. Let’s review together Pro & cons.

Pro:
– very portable, light.
– excellent reports
– magnetic antenna (low QRM)

Cons:
– price (more than 300$)
– no remote tuning available yet

alex_1The Alex loop antenna is inside this bag ! 🙂

Before there were two versions of the AlexLoop (a kit using copper tube for the radiating element with the cost of $199 US.) The other and now definitive version is the so called “WalkHam“, which uses stout coaxial cable (RG 213) for the main loop and comes ready built in its own custom made carrying case similar to a laptop case. The price of the AlexLoop WalkHam is $349 US.

alex_2-2 Alex loop antenna – as soon as you open the zip !

The loop is 1 metre in diameter and tuned using an air spaced variable capacitor with a 3:1 reduction drive giving a 4 : 1 tuning range: 10m – 40m. Most magnetic loops including home-made ones only manage a tuning range of 3:1: 10m – 30m or 15m – 40m.

Once again Alexander PY1AHD showing off his antenna!
The antenna is designed for QRP operations (max 25 watts SSB or 10 watts AM/FM) and can be hand-helded and tuned with the thumb during walks on pedestrian operation. You can also make it supported on a tripod and turned freely to kill noise sources. The AlexLoop will work perfectly only 1 meter above the ground, so you can support it on a tripod an operate confortable seated on a camping chair.

The AlexLoop is the perfect company for your camping, travel, hotel, ship as well it will work perfectly on balconies and windows presenting a omnidiretional radiation pattern.
