Re: [IRCA] Plotting a course to 1710 kHz Location
Hi Guy,
Thanks for your report on the Perseus' 1710 kHz investigation.
Your Perseus report is probably more trustworthy than the results I have
obtained using the 30" loopstick ICF-2010, which typically does not react
well to urban issues. The hot-rodded loopstick takes the spurs evident in a
stock ICF-2010, and magnifies them. Although very sensitive to DX, the side
effects can be disappointing-- and the KIRO/KOMO mixing product on 1710 kHz
may be one of these issues.
Anyway, I'll try a couple of other receivers (like the ICF-S5W and PL-600)
inductively coupled to the large loops here, and try for a bearing on the
1710 Russian. If they don't receive the KIRO/KOMO spur, it should be easy
to get an accurate bearing.
73, Gary

Hi Gary,
I'm finding the 1710 mystery Russian around the clock at my receiving
location in Puyallup, not just night time. Also, it's the strongest by
far of any signal surrounding 1710, as noted on the Perseus waterfall. (But
strong is relative--all the carriers are fairly weak.)
I noted the Russian varying slightly, 1709.987 - 1709.989 after I
calibrated
the receiver display around 10 a.m. PDT. At that time there were 13
carriers
found between 1709.9 and 1710.1! Now at 4 p.m. I only see two carriers in
that range.
I'm not sure if I'm seeing a KIRO/KOMO mixing product or not. There's an
*extremely* faint trace at 1709.999 kHz.
The Russian on 1709.989 shows a signal strength between -105 and -110dBm
right now, stronger than it was this morning (-118dBm).
So far I'm only checking the frequency with the NW Conti loop antenna;
before the day is over I will hook up the rotating ALA100 again and report
back on the bearing.
