Many thanks to SWLing Post reader, Colin, who writes:

This chart may be familiar to some, for others like me who has just found it, this will be a very useful one-stop information page for UK spectrum allocations for scanning the bands.

Thanks, Colin! Ofcom has done a fantastic job making this data accessible. Individual maps for each chunk of spectrum can be downloaded as well.

Can you help Chris ID this station?

SWLing Post contributor, Chris Smolinski, would like your help to ID a Spanish language station. Chris notes:

“I record the 6800-7000 kHz band every night with my SDR, looking for pirates, but sometimes I also stumble on other interesting transmissions. The other night (UTC March 8) I picked up a curious station on 6974.5 kHz AM, starting at 0119 UTC, off at 0137. It was a mix of music and possible IDs by an OM in Spanish. There is what sounds like a four character call sign as part of the ID, and mentions of what could be the Dominican Republic. My guess right now is this was some sort of a relay of a domestic MW or FM station.

I have two recordings here, perhaps someone can pick out the callsign or other parts of the ID? Not the best audio quality, but you know how that goes:”

James adds an LM386 amplifier kit to his Heathkit GR-150

Many thanks to SWLing Post contributor, James Surprenant (AB1DQ), who shares this update to his review of the Heathkit Explorer Jr. TRF AM radio receiver kit:

With regard to the Heathkit TRF AM receiver kit, I did indeed build my LM386 amplifier.

I was planning on home-brewing it from scratch as the chip is pretty much all you need and there are various proven schematics for the circuit, but in the end I went with a small kit from Nightfire Electronics for $10 plus $5 shipping that I found on Amazon.com.

It was a bit cheaper to buy it in kit form, of course, and then there was the convenience of having all the parts in one place.

Here is a photo of the kit as advertised on Amazon…

And here is my build with the Heathkit…

I modified the kit to add a 3.5mm input jack, replacing the RCA jack that came with the kit, to make it easier to plug into the Heathkit radio.

I deliberated whether to install the audio amp into the Heathkit cabinet drilling out a couple of holes for the pot shafts. It all would have fit and I could have easily mounted the 3″ 8 ohm speaker to the back panel of the Heathkit radio. In the end, I decided to keep the radio original and mounted the amplifier board on a small piece of wood I found at a hobby store and decided to leave it all exposed. It works well, all things considered.

(Click here to view video on Facebook.)

It worked well and per my original review on SWLing Post, I feel Heathkit should have included such a little amp in the kit – it makes a big difference.

Many thanks for the update, James! That little LM386 amp kit seems like an affordable addition for any receiver lacking an amplifier or adequate audio amplification.
