The best transceiver for a new ham and seasoned SWL?

The Yaesu FT-890: One of many general coverage HF transceivers spotted in the 2017 Hamvention flea market.

Many thanks to SWLing Post reader, Joe, who writes:

I’ve been practicing for my Technician ham radio license here in the US and am ready for the test. I’m already looking at HF transceivers even though I don’t have my General license yet.

Here’s what’s important to me:

  • I will still do a lot of SW DX
  • Something that has at least decent audio
  • Something that isn’t too too huge; though I’m a little flexible on size
  • I need something that has a receiver that handles weak DX well

I’d be comfortable spending $500 any day all day no problem. Anything higher than that and I’d really have to think it’s an investment in my radio future.

Thanks for your question, Joe, and allowing me to post it here for comment as this is one I’m frequently asked.

First of all, congratulations on studying for and taking your ham radio license exam! I’m a ham and absolutely love the radio privileges my license provides.

At the same time, I’m still more of an SWL than a ham–meaning, I spend way more time chasing SWL DX than doing on-air ham operations.

With that said, I always seek radios that will serve me well as both a ham and SWL, if possible.

My humble advice

If we stick with your $500 budget strictly, then we’re certainly looking at used transceivers. That’s okay–there are many good ones on the market!

I posted the following review of general coverage transceivers a few years ago. The info in it is still very much accurate in the used market. I would suggest you give it a good review as it goes into more detail about the ins and outs of your first transceiver and the importance of leaving budget to purchase a good power supply:

 If you’re willing to spend a bit more than $500…

I’m a big fan of the Elecraft KX3 and Elecraft KX2. I have both and use them frequently.

Comparing the size of the Elecraft KX3 (top) and KX2 (bottom) at Elecraft’s Dayton Hamvention booth.

You can find the KX3 used for $700-900 (depending on options). The bare-bones model of the KX2 can be purchased new from Elecraft for $749.

Of course, something to keep in mind about the Elecraft KX series transceiver is that output power is limited to 12-15 watts. Some of the general coverage transceivers mentioned in our review have a much higher 100 watt output power.

Additionally, the audio fidelity (via the internal speaker) is not as good as many other general coverage transceivers. Audio amplification is not as powerful, because both transceivers are designed to operate on a small battery pack (a major plus in my world because I love field-portable rigs).

Since I do 90% of my radio work with headphones, audio amplification is not a problem for me and I’m quite please with both KX line transceivers. Many KX series owners purchase external amplified speakers to improve audio.

The LnR LD-11 tuned to the Voice of Greece.

While we’re looking at QRP transceivers, I would also recommend the LnR Precision LD-11. Its broadcast afidelity is even better (via headphones) than the KX2/KX3 since the AM filter can be widened to an impressive 9.6 kHz. It’s a top-notch transceiver and can be purchased new for $780 US. Click here to check out my full review of the LD-11.

The Icom IC-7200

Of course, as I mention in the general coverage transceiver review, the Icom IC-7200 is also a gem of a transceiver.

Keep in mind, the ‘7200 was such a popular radio that after Icom discontinued the model in January of 2016–due to overwhelming customer demand–they re-introduced it earlier this year. No kidding.

New, the IC-7200 is about $879 US, but they can be found used closer to the $650 – 750 mark. A very good value in my book. In fact, I’m very tempted to buy one as my 100 watt “shack and field” rig. It’s way more user-friendly on Field Day than my Elecraft K2/100 and, in many ways,  a better option than purchasing an Elecraft amp for my KX3/KX2.

Any other good suggestions?

The Kenwood TS-480SAT is full-featured, small, and has a detachable face plate. A very good general coverage transceiver.

There are hundreds of HF transceivers on the new/used market. I’m sure I’ve missed some excellent options in this post and my general coverage transceiver review.

Please comment with your favorite dual-purpose Ham Radio/SWLing rig. Tell us why you love it!

Project Amelia Earhart: work an air mobile station as it travels the world

Here’s an opportunity for both ham radio operators and SWLs to log this special event air mobile station throughout June and July. Based on WB6RQN’s flight path, almost everyone should have an opportunity to put WB6RQN in the logs!

The following excerpt has been copied from the Project Amelia Earhart website:


About Ham Radio on the Spirit

Brian Lloyd has a powerful radio system aboard the Spirit. The radio communicates on High Frequency (HF) shortwave using Single Sideband (SSB), and anyone can tune in to these transmissions who has the proper type of radio receiver. Listen for WB6RQN, that’s Brian’s Ham radio callsign. Ham radio operators around the world are invited to communicate with Brian while he is on the air in international airspace using the Ham bands. HF radio is dependent on ionospheric conditions to be heard over long distances, and it may change rapidly with the space weather or other factors.

Ham Radio Technical Information

Ham Radio Callsign: WB6RQN
Operator Name: Brian
QSL Via: eqsl.cc Electronic QSL system
HF Radio: Mobat model Micom 3, commercial HF transceiver
HF Power: Maximum power 125 Watts, 2-30 MHz
HF Antenna: Tapered Towel Rack type Belly Wire, with Automatic Tuning Unit (ATU)

Ham Radio Frequencies of Operation for Spirit Flights

HF Frequencies for Ham Radio SSB Voice QSOs and DX: 

  • Ham QSO activity may occur at any time while the airplane is in International airspace, USA, or some other areas.
  • Ham operation may happen while Brian is not busy with flight operations
  • There may be unexpected interruptions during a QSO
  • Please be especially courteous and patient, because his first priority is to pilot the plane.

Simplex or Split? Most of the time, WB6RQN will use simplex, listening and transmitting on the same HF frequency. But, sometimes Brian may ask calling stations to transmit “UP 5” split. When using UP 5 split, your transmit frequency must be exactly 5 kHz above WB6RQN. The plane’s HF radio is channelized, and it does not have an S-meter.

Brian said, “During the actual flight I can talk on ham radio when I’m not using the HF radio to make position and status reports to Air Traffic Control. I will probably get 10 to 15 minute windows when I will be able to work ham stations on the HF bands occasionally. I have never been a contester, so my QSO rate will probably be lower than most ham operators would like.”

HF Channel Frequencies for Ham Radio ALE Activity: 

  • Activity using common Amateur Radio standard 2G-ALE Automatic Link Establishment may occur on the following scanned channels when Brian is not busy with flight operations.
  • ALE activity may occur at any time while the airplane is in International airspace, USA, or some other areas.
  • Whenever the ALE soundings of WB6RQN are heard, operators are invited to call on any one of these channels using an ALE Individual Call and link with WB6RQN.
  • When linked on an ALE Voice channel, the preferred QSO method is Upper Sideband Voice.
  • If a text is to be sent, use AMD and include the AMD text within the initial Individual Call.
  • Do not expect a wordy text reply, because there is usually no QWERTY keyboard connected to the ALE radio in the cockpit.
  • Anyone copying soundings, calling, or other types of reports is encouraged to post ALE reception logs on the HFLINK.NET website.

SWL and UTE Monitoring of HF Aero Frequencies

For SWLs (Shortwave Listeners) or UTEs (Utility Monitors), it is possible to listen to Spirit on the Air Traffic Control (ATC) HF Aeronautical frequencies with an SSB (Single Sideband) receiver. More information about listening to Spirit on HF Aero, click here.

Video: EB3DYW’s Homebrewed regenerative receiver

While browsing a videos on YouTube, I stumbled across this demonstration of a brilliant little homebrewed regen receiver by Javier Guillaumet (EB3DYW):

What a beautiful little receiver!

Though I’ve build a number of receiver kits, I’ve never built one from scratch. Someday, I will muster up the courage and do so, though!

If you like home-grow regen receivers, you must check out Dave Richards’s Sproutie II regen receiver as well. A true work of art!

Buyer Beware: Dan shows us how to spot a scam on eBay

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

This is an example of a classic scam — and these are usually seen involving
Watkins-Johnson 8711/A receivers.

The seller puts a photo of what appears to be a good condition WJ up,
with additional photos. But often these photos are faked or taken from
other ended Ebay auctions.

The description is usually, as with this item, in blue letters noting
the item is available only for immediate sale, and not for auction,
despite the fact that the auction is — an AUCTION and has a
starting price.

I make it my business to reports items like this to eBay and eBay has
a pretty good record of recognizing scams and removes them.

I think it’s important to point out these items to SWLing readers to
help avoid people being ripped off.

No doubt!  Thank you so much for sharing this, Dan. I didn’t realize scams like this were prevalent on eBay.

I’m willing to bet this scammer’s plan is to get you to outside the boundaries of eBay’s protection as soon as possible, luring you with a believable bargain price. This is why they ask for you to message them instead of bidding.

In my opinion, eBay is one of the safest sites for online purchases, but it is certainly not void of scammers. Remember the proverb, “If it sounds too good to be true, it probably is!”

Thanks again, Dan!
