28605 Khz?
« on: March 27, 2022, 2144 UTC »
Anyone else hearing R. Habana on 28605 Khz, AM mode?

Currently receiving this, here in northern Michigan at 2140Z.

I see they have a 9535 transmitter but it is not shown as on-ar at https://www.short-wave.info/index.php right now.

9535 x3 = 28605, third harmonic

Follow-up:

I checked 15370, which is shown as currently active for R.H.C., and it is the same audio feed but sounds raspy - perhaps over modulated a bit.

The modulation on 15370 does not appear to be symmetrical on my SDR, but it's hard to tell if that is a transmitter fault, or due to selective fading.

 Ct Yankee - yes I noted the possibility of 9535 as the source, but it is not shown active right now.  I have a carrier on that frequency but can't recover enough audio to ID it.

Can you hear RHC on 9535?

Yes I can (matches 15370) but nothing on 28605....we just switched to the A22 broadcast period today., it takes about a week for everyone to update listings.  Happy listening  :D!
