Now that I have a working experimental signal on 13.56 mHz, 21 meter band, I’m thinking about a shortwave radio in the car so I can DX the signal. Has anyone had experience with an auto SW receiver?

converter…
Clare in the olden days we used to use a shortwave converter for ham use. It goes between the car antenna lead and your car radio and converts the chosen SW frequency range down to the AM broadcast frequencies. It would be a little harder these days with the digital frequency selection of the modern car receiver but would still be the best solution if one could be found. I’ll run off from here a see what I can find. Maybe MFJ co. or? If I find something I’ll get back here. Dave
Shortwave converter
Clare I googled “”shortwave converter”. There are several entries. One was the Ramsey SC-1. It is 9.95 I think and it would probably do the job for what you want. I didn’t check the schematic but if the local oscillator is crystal controlled you will probably need to add a “padding” capacitor across the crystal to “net” the incoming shortwave frequency to your cars digital channel to get right on frequency. should be easy. Hope this helps. Dave
SW in a car
Older European car radios used to be available with shortwave bands,but they are hard to come by. Most only covered 49 meters. The best alternative is a shortwave converter like the MFJ308($124.95) or the Ramsey SC1,or a very high end scanner that has shortwave bands like the AOR AR3000,but they are pricey. My AR3000 cost me $1495 10 years ago!!! You could also build a converter,they arent all that complicated.
Be careful
In some states it is illegal to have a scanner in your vehicle unless your a ham, fire, ems or police. Kentucky is one of those odd places where it is illegal.
Just throwing that caution out there, on the upside a scanner with shortwave makes for a sensitive receiver.
Years ago I knew a guy who had a shortwave car radio that was made by Blaupunkt. Might look it up on ebay or rigpix.com.
Im not sure what the model number was.
I dont own a shortwave anymore but use many online receivers so i will try to listen from time to time, maybe ill hear your station.
Good Luck & 73’s
Sony made one targeted for
Sony made one targeted for Europe – it’s basically a car cassette stereo with added s/w bands. Can’t remember the model number, but I will check (I have one laying around somewhere). Can be picked up on e-bay, where I got mine, fairly cheaply, although somewhat uncommon.
