Hereby we collected for you some nice link where you can download some of the best ham radio software for apple MAC and macbook users.

MacLogger DX 
It’s very good and sophisticated app for MAC users to help ham radio amateurs to log every information before their sending QSL cards.  MacLogger DX is shareware:  after 90 commercially-available … you have to pay for it. You can display 2D and 3D representations of DX clusters by band, and this software has built-in support for ham call sign databases so you can immediately tell where your contact is broadcasting from.  MacLoggerDX supports close to a hundred radios, automatically tuning to the spots you are interested in, swinging your beam around. Alerting you to rare contacts or Band Openings and looking up, displaying on 2D, 3D and Satellite Maps and logging your contacts to a super fast sql database. MacLoggerDX can also text or email you when the Bands are open or that rare DX is spotted. Awards Tracking, Band Activity, Schedules, Memories, QSL Generation, ADIF import, export, Club Log integration, eQSL, LoTW Confirmations and much more.You can download it from here

Here another ham radio software for Apple mac (macbook)

Elmer is a very nice application to provide practice examinations from the common pool of test questions provided by the Federal Communications Commission. You can take practice exams for the Technician, General, and Extra licenses as many time as you want. 🙂 Elmer also comes in three separate apps for iPhone and with these iPhone apps you can go with you anywhere, which is important while studying for the exams — trust me, you’ll want to study in every free minute you have.

Morse mania
Morse Mania [US$19.99], a Morse Code tutor for the Mac. The application can be used to learn individual letters, groups of letters, and to simulate full conversations with other hams.

We believe this is one of the best app for mac users:  This is a Mac OS application which implements modems for some of the Amateur Radio modulation modes. cocoaModem’s name is a reference to the MacOS X Cocoa framework that it uses.  You can finally do perfectly with no problem PSK31 – CW and other digital modes like RTTY, Hell, DominoEX, Olivia.

Wanna be the best ham radio amateur with your macbook? or iMac? You should download this app. FLIDGI is a nice modem program for most of the digital modes used by radio amateurs today: CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, and Throb are all supported. It can help calibrate a sound card to a time signal and do frequency measurement tests. Download it here.

If you own a Elecraft XK2 you should download this app that allows you to remote control your Elecraft XK2.A Remote Control

Elecraft KX2 Transceiver

Elecraft KX2 Transceiver

Elecraft KX2 Transceiver
– Simply the best –

Great news! Last May 19th, at 1300h Elecraft INC has released to the world the new Elecraft KX2 Transceiver! This will be the last engineer opera from this great company : after the KX3.
Screen Shot 2016-05-18 at 20.35.43

It has presented as a “fit in your pocket size transceiver“.  It is small, cheaper (only 749$) and powerful. What do you need more? That’s simply fantastic. It’s the resolutive QRP. Elecraft has featured the KX2 at the “Four Days In May (FDIM)  Dayton Hamvention”.

The Elecraft KX2 transceiver measures 5.8 x 2.8 x 1.5″ with a weigh of 13 ounces (350 grams)!!!
It covers 80/40/30/20/17/15/12/10/6 meters band! This will be your best friend during your SOTA activation or during field day / camping trip.

Screen Shot 2016-05-18 at 20.34.48

The new KX2 Battery and Charger system
Apparently Elecraft will be stocking the KXBT2 (Li-ion Battery) and the charger (KXBC2) for your to order. The battery is 2650 mAH, enough for our QRP operation, yielding up to 8 hours with a single battery charge. There is obviously an internal automatic tuner module (KXAT2) which can tune a random wire or whip on every band.

The DSP present in the Elecraft KX3 is also present in the Elecraft KX2 transceiver with a powerful 32-bit DSP which offers dual watch, noise blaming and reduction as well auto-notch. RTTY and PSK data modes are already built in. No PC needed. Digital voice recorded INCLUDED!

Accessories are following:

Screen Shot 2016-05-18 at 20.33.29

What do you think? We believe that Elecraft KX2 transceiver is, at the present time, the best SDR portable, compact HF radio you can desire. Lighter and powerful of Yaesu FT 817.
That’s true: you will not have 2 meters band and main complain will be the non-rugged construction. It will be always a sort of “jewel” to keep under a crystal window. Definitely not to take with you in the Jungle.

Please share the news and add your comments down here.

Yaesu FT 817 on the citizen band

Yaesu FT 817 on the citizen band

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.

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!

QRP TEN-TEC 539 Argonaut VI transceiver

QRP TEN-TEC 539 Argonaut VI transceiver

QRP TEN-TEC 539 Argonaut VI transceiver

This transceiver is the new Ten-Tec QRP on the scene.
It is the model 539 Argonaut VI: a 10 watts  CW/LSB/USB/AM transceiver.


The Ten-Tec model 539 Argonaut VI is an attractive and very simple little radio. On the front panel there are only two knobs: one controls the AF gain, with the outer ring that controls RF gain. The other knob controls the bandwidth, while its outer ring controls the pass band. There are also four multi-function buttons, and a three-position toggle switch.

We read some negative comments about this radio, like why no 6 meters? or some of the other frequencies ?
But compared to an elecraft K2 we didn’thave complains about not having the amount of ham bands that the Argonaut Vl has. Look at the K1 : you get only 4 bands and no phone (microphone) just CW. We liked ten tecs simplistic approach. Every Ten Tec radio has a beautiful, elegant QSK – a hallmark of Ten Tec.
In the photo down here the Ten-Tec 539 Argonaut compared to an Elecraft K2
The ten tec 539 wins for audio fidelity, simplicity and weight but drains in rx more power


  • New Sensitive VFO tuning rate
  • 9.5 to 14 V  –  DC power requirements
  • Dynamic Range of 91dB 2 kHz
  • 1 up to 10 Watts power output
  • Keying output for 100 Watt with the Solid State Linear amplifier Model 418
  • Operate digital modes with full rated output
  • Legendary TEN-TEC quality QSK CW keying
  • Roofing Filter Standard 2.9 kHz  Included 2.5kHz effective through DSP

There are only two major cons:

  • No 12 and 60 meters.
  • No internal ATU – automatic antenna tuner and there isn’t an option for one
  • No internal batteries.


Here there is a video – full review of Ten-Tec model 539 Argonaut VI 


Elecraft KX3 and 27 mhz (CB band)

Elecraft KX3 and 27 mhz (CB band)

Elecraft KX3 and 27 mhz (CB band)

Hello everybody,
somebody can turn up his nose if we talk of the best SDR transceiver that we want able to transmit on the 27MhZ (CB Band). Well, it’s true. We can use a simple 100$ Citizen Band transceiver – and enjoy it but… the first love will always be for ever! I believe 90% of us had first ham radio QSO on 27.555 MhZ – USB. At the end of the day, we happy user of KX3, would like to have the opportunity to transmit on the CB band / 11 meters band!

CB band SSB
CB band SSB transceiver

I did a quick search on internet to look for mods for our Elecraft KX3 to be able to transmit on 27 MhZ (CB band). The best would be to find mods for wide band transmitting. This is what I’ve found for you.

It seems there is a “widebander software tool” that is able to do the job…  (expanding the bands but except the 27 Mhz band). Just look for it on the net.

The best thing to do is to contact the Elecraft support team as I did:
You can (or at least, used to be able to) ask Elecraft for the K3 MARS TX unlock software. Here is the information received from Elecraft:
“Please find hereby attached the software to remove the TX Band limit and you’ll be able to work MARS frequencies. It is upon to the radioamateur to make sure he’s operating in conformity of law over the authorized frequencies. We cannot be held responsible for any unauthorized operation.

Please note that CB band is blocked for transmit at high power. It will not engage the KPAxx on this band. You can transmit. Only at low power (10-12watts). Do not forget to share with us your mod if you’ve found one! If you like to have more link / video please send down your comment. We, Elecraft KX3 users, would like to have a open band transceiver! 🙂 PLEASE, ELECRAFT, let us do the mod 🙂 It should be easy for everyone. It looks like somebody did it and he is able to transmit on the citizen band. . .only 5 watts yes, but this OM did a great job (we cannot tell more but …you can go here): click down here on the arrow.

Balun designs

Balun designs

Balun designs

First of all , please remember:
Baluns will not improve SWR (the exception is where a balun used as part of a matching network,
I like to design and creat baluns by myself. Quality is top notch. Don’t waste your money buying some of the cheap china knock-off’s. Do by yourself. Follow our balun designs. Well made.

The balun should do only two jobs.
1.Isolate transmission line
2.Provide balanced output current

Proper balun designs
A properly engineered balun will include these design points: High winding inductance (reactance) and Low stray capacitance. Very short internal transmission lines- << 1/4 wave (remember:  the shorter the better). High power components- High voltage wire and insulation to withstand high power or a mismatch. Large wire gauge reduces I2R losses. Large cores because help to prevent saturation and provide the necessary high inductive reactance values on the low bands.

High power handling
Minimize resistive losses
Correct core selection
Robust mechanical design
Line Impedance, Z0
For 1:1 make equal to load and line impedance
For 4:1, make geometric mean of line and load impedance (e.g., 50Ω to 200Ω requires 100Ω line)

What is software defined radio

What is software defined radio

What is software defined radio

Very simple to answer. The SDR (that’s the acronym) is a new concept that is arising since 30 years in the ham radio (but not only) field.

What is software defined radio
What is software defined radio

It was the 1983 when the first software defined radio was introduced. That’s because semiconductor technology has improved both in terms of performance capability and cost. Technology like SDR (software defined radio)  have emerged from military and research and development labs.

What is Software defined radio?
Software defined radio is a radio that has the ability to be transformed through the use of software or re-definable logic. This radio is able to take advantage of digital processing. To do that, the traditional analog signal must be converted to and from the digital domain. This is accomplished using analog-to-digital (ADC) and digital-to-analog converters (DAC).

What are the limits of software defined radio?
Despite the fact that an ADC or DAC connected directly to an antenna is a desirable end goal, there are issues with selectivity and sensitivity that an analog front end can remedy. The alternative to digitizing at the antenna is the use of a completely flexible analog front end (AFE) capable of translating a wide range of frequencies and bands to that which the data converters themselves can adequately process.

Software defined radio is the ideal candidate to be used for multi-carrier, single-carrier, single-band, multi- band and multi-mode transceiver.

In the case you are still asking What is software defined radio .. we can say it is implementing a receiver together with the  transmitter) in a software. Such software defined radio will perform much better than an analog one, because filters can be made much closer to ideal (steep slopes, high rejection of unwanted RF signal. Do not forget also the advanced algorithms can be implemented to do things that are not so easy in analog hardware (e.g., automatically tuned notch filters).

Advantages of software defined radio:

1) Design Flexibility
2) Upgradable
3) Reliability
4) Reconfigurable
