Hi Chaps
I'm hoping somebody reading this excellent reflector will be able to
offer some help.
I have an Argosy II here for a 'test drive' with a view to buying it but
there is, I think, a problem with the setting of the carrier oscillator.
I've not (yet) been able to put a frequency counter on it, but have been
trying to set-up C1, C2 and C3 on the ssb generator board.
However, there seems insufficient adjustment available on the trimmers.
At the moment, switching between SB-N and SB-R appears to produce
roughly the right result, but I cannot get enough 'offset' when the rig
is in cw transmit. Instead, I have to offset the rx when working a cw
station on my tx frequency.
Might this be due to an ageing xtal, or could there be another solution?
In addition, if I switch into circuit the 217 (500Hz) narrow cw filter
there are two further problems. Firstly, when the received signal is in
the centre of the filter passband, the resultant audio note is very low
indeed - maybe 250 - 300Hz. Secondly, there is excessive attenuation
through the filter - an S9 signal will drop to around S1.
The very low audio note would suggest that the carrier oscilator is
still off frequency, so maybe the two problems are related?
I wonder if anyone with experience of the Argosy II can offer any
comments? Many thanks.
