[PCR-1000] pour HF performance

[Bryce Ringwood]

Hi Matty,

Its possible for the RF stage on HF to degrade, whilst other bands
higher up the spectrum are OK. The PCR1000 uses separate RF stages for
each band. From memory, the first stage operates from 0 to 50 MHz. Its
hard to say what you should and shouldn't be able to receive depending
on your qth, but with even a short outdoor aerial of a few metres, you
should be getting some DX on 20 metres (occurs in the late afternoon in
S Africa). You should hear WWV on 10 MHz anyway. You should also be able
to receive aerial noise in the absence of a station.

Check your aerial connectors - I spent about an hour trying to figure
out why my R390 had gone dead until I found one of the BNC connectors
had come adrift. 

A thorough check on the Rx needs a really good signal generator and
check against the specs in the service manual.

Hope this helps.
Regards - Bryce

Hi All
I am connected with the Radio shack discone antenna. My RF
performances
is really bad and I can not receive even one ham or sea to land
transmissions. I only receive very strong SW signals. Are there any
beacons that I can test my reception?   I have a bad feeling that some
thing is wrong on the SW bands on my receiver. On VHF and UHF the
reception is ok. Is the SW condition fading with time? I use to
listing
to SW like 10-15 years ago and it seems that then there was much more
to
hear? I must say that then I used a Collins 51S.
One more question is there a program that can tell me what is the best
band to listing to according to propagation conditions?

Thanks
Matty
