Could you please offer any specific tips on:
- Your antenna
- Minimizing RFI
- Connecting radio
to PC (or you just use your PC mic?)
Reason I ask is I tried a Tecsun PL 660 (bought new on Amazon) in San Francisco
last fall with very limited success on SW frequencies, particularly USB. I tried both the built-in antenna
and the basic 5m wire antenna, but mostly got garbled reception
. For example, I could only passably hear the Colorado WWV time tick, and only a few times heard Hawaii
WWVH despite trying different times, frequencies, etc. Also on SW, I could hear Radio Havana very well, some evangelical stations, and often heard Chinese/Japanese/Southeast Asian commercial
stations. But heard next to nothing on USB, including none of the USCG HF voice broadcasts (whether nearby or not), none of USCG radiofax signals (even after 1.9kHz offset), etc.
I was listening from rooftop of a midsize apt building on top of a hill, so I imagine RFI was one of the problems, but still not sure if i also needed a better external antenna or there was operator error. I tried turning off my phone
, staying away from power cables
, etc to minimize my nearby RFI, to no avail.
A friend later tried the exact same unit in the Philippines
on a boat during a passage
and heard nothing on USB either (including no UCSG Guam), but again heard some commercial
channels on AM, including Guam
. Should have been less RFI there (he tried from the foredeck).
Long story short - we never figured out how to tune in to any available weather
source (voice or radiofax). Searched CF for tips but couldn't find anything that helped, other than return to stone age and disconnect all electrics/electronics (which clearly isn't always practical).
Your tips would be greatly appreciated!
