Welcome to our latest episode!
We hope you like the new theme tune!
In this early summer episode we look at programming your DMR handie and running a SharkRF openSPOT digital radio IP gateway. We review the new Icom IC-7610 transceiver, and Mike visits Bob’s shack in Cornwall to learn more about operating through linear satellites.
In our free-to-enter draw, there’s a chance to win two great amateur radio-related items. How about a Prism protective dust cover for your rig and a copy of Andrew Barron ZL3DW’s bookAmsats and Hamsats? Click here!

Thomas (N1SPY): How to chase Cubesats with an RTL-SDR dongle and some wire
Many thanks to Ivan (NO2CW) who writes:
Thomas, N1SPY used equipment worth $25 to chase mini satellites. Includes instructions for making a simple circularly polarized antenna. Did it work? Check for yourself!

Thanks, Ivan, for passing along another excellent project by Thomas (N1SPY). I love how simple this project is to put together and the fact that most SWLing Post readers, for example, likely have all of the components already! Great job, Thomas!

How are you doing? I have found a recording on the archives of a recent North Korean recording of the Voice of Korea on the Panmunjon Summit, between both North and South Korean leaders.
Not only am I pleased with the news, but I have uploaded the full 1 hour recording of the English broadcast on my YouTube Channel:

Great job snagging this particular VOK recording! You’re following a long tradition of SWLs before you who’ve made an effort to capture these fascinating bits of radio history. Keep up the great work, Dean!
Ivan performs two tests with the AirSpy HF+
Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who shares the following:
Thomas, there has been a lot of discussions regarding Airspy HF+ ever since it came out – heated exchanges regarding comparisons with peers, modifications and firmware updates.
I took my Airspy HF+ and conducted two tests with it:
Airspy HF+ vs. SDRPlay RSP-1A on HF and Medium Wave

Since I could not completely equalize the audio levels, I think it’s good to look at the peak to valley ratios on the display rather than the audio volume.

This comparison used SDR #. It may be helpful to run the same comparison on SDR Console V3. I may do that at a later time.
Both tests used W6LVP’s portable amplified receiving loop antenna in a noisy suburban backyard in Florida.
Many thanks, Ivan, for sharing these comparison tests! I agree with you that it’s most helpful to look closely at the peak to valley ratios on the spectrum display rather than using the audio levels as a measure.
