I received my new (used) Scout yesterday.
After a long search, I finally found a power plug and 9A Airpax circuit
breaker in my junkbox.
I built a cable with the breaker and am powering it from a 963.
The Scout came with band modules for all bands except 17 & 12.
There is no NB.
The RX seems to work fine on all bands.
On two of the bands (160 and 40m), I get very low output power - about 8w
and 2w.
On all other bands it easily brings 50+ watts on my cheap watt meter (10%
accuracy).
I changed modules quite a lot, making tests first on a dummy and then on
an
antenna.
At one point 40m suddenly worked, with full output power.
I made several 40m SSB QSOs with it.
Later when I plugged the 40m band module back in, the power was again 2w.
When I get the 2w, the SWR also shoots up. When it was working properly,
the SWR was good.
I have studied the diagram of the band modules.
Since the RX seems to work properly, I assume the oscillator and mixer of
these modules are working OK, as well as the HPF on the 160m module and
the
LPF on the 40m module.
The only thing left is the actual Bandpass Filter for the TX. It is
encapsulated in shielding and I can't really get at it.
I have re-soldered all connections on the bottom of the PC board but no
change. Still 2w.
I can't see how it would be anything but the BPF - or am I missing
something.
Any tips?
