Thomas,

I stumbled across this listing for a Panasonic RF-3000A so I thought I’d share it in case some SWLingers interested in or who collect vintage solid state radios are interested in the following listing for a Panasonic RF-3000A for US$125.00.

Thank you for the tip, Julian! I don’t think I’ve ever seen this model of Panasonic before. At first blush, it looks like a Barlow Wadley.

Based on the description of the radio, it sounds like it might need a little work. I think a re-capping would be in order and I’m sure the pots and switches need an application of Deoxit.

Perhaps our resident Panasonic collectors will let us know if this radio is rare or common? I doubt it’s exceptionally rare since there have been 3 offers made on it in the past. Please comment!

The journalist added that he hoped for a high-quality investigation and clarification of all the circumstances of the case:

“After my statement, the investigators of the SBU of the Lviv region conducted an inspection of the premises and seized a device that is a device for listening and recording information.

The AMT-MW207 mini AM radio transmitter kit

Many thanks to SWLing Post contributor, Frans Goddijn, who shares the following video demonstrating the AMT-MW207: a tiny $25 mediumwave transmitter kit that can be purchased on AliExpress:

To be clear, the AMT-MW207 is not designed to be a whole house AM transmitter like the SSTran and others.

The seller describes it as a device to debug and test AM receivers. Since it only employs a built-in bar antenna, the transmitter would need to be placed in close proximity to the receiver.

Thanks for the tip, Frans!
