4775 PRU Radio Tarma 0945 UTC 24 Feb 2024

Recently only Peruvian into PA has been 4820 R Senda Cristiana but this morning Radio Tarma is pretty strong with only that weird swooping radar (?) noise. This is a nicer local reception for me because it's one of the historical ones while the other one wasn't around 40 years ago when I was really into this.  Of course, there were as many as 100 other Peruvians at that time but I prefer not to think about it, too depressing!

That swooping radar noise isnt radio tarma..its coastal ocean dynamics application radar.

[Ron - Calif.]

Hi Paul - The coastal ocean dynamics applications radars (CODAR) have been observed with a variety of CW IDs around 4775 kHz.
One such ID was for WRPV785 ( https://www.radioreference.com/db/fcc/callsign/WRPV785 ), being operated by the Univ. of California
at Davis, with CODAR sites north of San Francisco.

Here at Asilomar State Beach (near Monterey), where I do my SWL'ing, CODAR is rather strong. Article about Monterey Bay CODAR HF radar - https://calhoun.nps.edu/bitstream/handle/10945/41229/cook_paduan_mapping_surface_currents_1997.pdf?sequence=1&isAllowed=y .

Hi Paul- I meant that radar was competing with the actual Radio Tarma signal

Ah ok, I know what a great log that would be from State College, so I didn't want you thinking you had something you didn't

By the way, I lived in Ridgway PA for 4 years, just 90 minutes north of you... did the Afternoon drive show at 97.5 The Hound WDDH

I've heard Radio Tarma up here in Alaska several times right around 0000UTC in the middle of winter. Soemtimes its been very good, despite getting the piss slapped outta it by CODAR.

Heres some audio.. it gets real good after 5 minutes in

My PA reception was on the Milford PA KiwiSDR, so in my state but not my radio! 40+ years ago there were dozens of Andean stations that were pretty routine DX into the northeastern USA, to the point where we'd try to hear what was behind them.  I think Radio Tarma was one of the DX-but-not-exceptional ones.  Just like this recent log, early mornings usually beat late evenings for rare Andeans.

More generally, I think it would be fun if HFU had a SWBC DX history page, besides the pirate history page.  I suspect I'm not the only one who would love to reminisce about old DX targets.
