Not sure what I'm hearing but it almost sounds like an old time weather fax on 9.108.5. Is that what it is?

20:16 UTC Saturday the 8th.

HF Mystery Signals / 1.945 LSB Strange Signal
« on: December 26, 2021, 1600 UTC »
Does anybody else hear a strange digital ticking like signal on 1.945 in the 160 meter band? I used to think it was some goofy rf somewhere in the house but a friend of mine can hear it 60 miles away.  Sure is strange sounding.

Hello MRI, I would be very interested in the mod to make the R-390a go below the broadcast band. I have done only the AGC diode mod which works very well. Can you enlighten me on what that LF mod might be?

Thanks!

Actually a good larger 600 ohm speaker like an old Hammarlund or Hallicrafters will give you an excellent result per radio spec without having to go to the amplified speaker route because of only having an 8 ohm speaker on hand. Most SWL hobbiests won't have a 600 ohm speaker sitting around.  True, warm tube audio from a radio is certainly a plus BUT a small amplifier with controls for treble and bass sure doesn't hurt either if you need to go that way!

Thanks for your thoughtful reply!  I personally do not compare mine to all my digital radios including my newer Icom 7610 because IMO they are two completely different animals. I rarely use my R-390a for the ham bands as I agree my current rigs are so much easier and enjoyable to use for that. It is certainly not my choice for SSB reception either although I can get it sounding decent in that mode. I like it mainly and pretty much solely for SWL AM, numbers stations AND especially Broadcast Band DXing. In my opinion, broadcast band listening at night is where the R-390a shines. There is simply nothing that comes close it (all my rigs digital and otherwise including my RACAL 6790) can't touch it. A properly aligned R-390a is simply magical in what is discerns on the broadcast band. Spend the hour or so it takes to properly align one of these and you will be rewarded. You have to use a 600 ohm speaker OR a small amplified speaker hooked into the back or the headphone jack but doing that will provide deep, outstanding, room filling audio.  Enjoy the listening fellas from an extra in W8 land!

I have been using the R-390a for over 40 years in my shack.  My shack is fairly extensive but I always seem to gravitate to using the R-390a for all types of listening. I have 3 of them including one at my cottage in the ultra-quiet listening environment along the shores of Lake Huron. I'm curious to know what other users think of them.

I hear it here in Michigan at 22:50 UTC. Nice find as it is not very strong and easy to miss unless you are looking for it. 

ICOM IC7610, antenna is end fed.

20 over S9 in Michigan. Guys voice sounded like WA4D legendary obnoxious QRMer.

Was S9 here in Michigan but just died with "My Sharona".

Very strange programming choice. Wouldn't exactly call it enjoyable listening.  Still, the signal is S9 and good in Michigan.
