Shortwave Audio | The SWLing Post

Many thanks to SWLing Post reader, Ron Wagner, who writes:

Thanks very much for your informative SWL pages. With the, seemingly, shortsighted, contracting world of SW broadcasters, you keep our interest alive!

Recently, you called attention to Jay Allen’s modification and installment of a new speaker for the Satellit 800. Not quite ready to open up my 800, even with a scratchy volume pot, I setout to find another way, not only for the 800, but for all of those older radios that “SWLers” love.

Walla, a Bluetooth TX/RX device (by JETech Designs) which connects to the headphone or external speaker jack of the radios. Then, with a Bluetooth speaker, put the TX/RX device on TX and pair with the speaker, and your off to an audio improvement in all of your radios.

Attached, see the TX/RX with my 800, G3 and ICF 7600 and my outdoor Bluetooth speaker. With today’s Bluetooth speakers, you can spend to suit your budget and ears. Now, I’m on my way to find Bluetooth headphones to pair with the Bluetooth transmitter.

What a simple and relatively affordable idea, Ron. I had been considering the purchase of a Bluetooth receiver for the AUX in port in my minivan’s audio system. If I understand correctly, this one unit can both send and receive Bluetooth audio. Very cool!

I could also imagine someone placing their shortwave portable outside–on a patio or deck–away from indoor radio interference, and using the Bluetooth link to port audio to a speaker inside the house. You wouldn’t have tuning control (and you’d have to remember to bring the radio inside if rain is in the forecast–!), but you would have audio control.

Looks like this JETech receiver/transmitter is available on Amazon or directly from JETech. Thanks again for the tip, Ron!

Last year at the W4DXCC conference in Sevierville, Tennessee, I spent some quality time with Bob Heil (K9EID). Bob is the mastermind behind Heil Sound as well as the host of HamNation, a show devoted to all aspects of amateur radio––yet this job description only scratches the surface of Bob’s fascinating career.

One thing is for sure, however: there are few people in the radio industry who truly understand audio as profoundly as Bob Heil, so when he announced that he would host a forum at the W4DXCC to assist amateur radio operators in improving their received (and transmitted) audio, we were all ears, and signed right up.

Early in the forum, Bob described a set of self-powered and relatively affordable JBL monitor speakers that he highly recommended for amateur radio use. Everyone in the room noted the model number of the speakers, myself included. So imagine my dismay after the convention when I simply couldn’t find my notes…

Thankfully, my buddy Gary Wise (W8EEY) recently jogged my memory. Gary purchased a set of JBL monitors and matching wall-mount brackets from Amazon, and has them hooked up to his Flex Radio FLEX-6700 SDR. Gary tells me he’s very pleased with the set-up. Here are the links:

Bob also suggests adding a small mixer to system, something like this Behringer Xenyx 802 or the XENYX502 (both of which are on my current wishlist).

Bob invited me to speak on HamNation about shortwave radio. I may take him up on the offer…well, as soon as I overcome my videophobia, that is. At any rate, if you’ve not seen it, HamNation is certainly worth checking out. And in all things radio, Bob Heil’s is a name to know; click here to visit Heil Sound.
