Thomas Cholakov (N1SPY) picked up an old General Electric radio from the 2019 Orlando Hamcation and brought it back to life. Unfortunately with all of the radio’s 7 bands, it did not have shortwave.

Brilliant job resurrecting that GE portable, Tommy!!! Thank you for sharing.

Thomas, I’m sending you a short clip from WWFD 820 kHz in Frederick, MD. It’s America’s only all-digital station, apparently. They are HD only with a relatively eclectic music format. I’m hearing them at my QTH in Harrisburg, PA, about 80 miles or so north of their transmitter which is 4.3 Kw daytime. I sort of doubt they’ll come in at night when they drop down to 430 watts, but who knows.
My experience with HD on MW is that it can be heard at pretty decent distances under ideal conditions but the slightest bit of interference, a lightning strike or someone switching on the lights for example, and it’ll lose the HD lock.
My HD receiver is a Sony XDR-F1HD. It’s well-known as an excellent FM DX machine. What’s not as well-publicized is that it’s a very decent MW receiver as well. All it needs is a good MW loop antenna directly connected to the AM ANT terminals on the back of the radio.

Excellent! Thanks for sharing, Bill. I’m passing by Frederick, MD in a couple of weeks and plan to tune to WWFD in both my car and with the Sangean HDR-14.

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.
Many thanks to SWLing Post contributor, Moshe, for sharing the following video:
I uploaded this video I made in a rush, holding our baby in one hand and my smartphone in the other one…
The receiver is my Ben-Gal Verdi.
I caught the station by accident, while tuning to VOA 15580kHz to listen to Boarder Crossings.

Fantastic catch, Moshe! Thank you for sharing. I can’t tell you how many times in the past I played radio while also holding a baby in my arms. Always a challenge!
