Hamscope in Action
Ran into this free
program online called "Hamscope". Although it must certainly have many
capabilities beyond what I have learned, I immediately recognized its
value for tuning in CW signals. Also I can see significant use for it in aligning a QRP receiver.
This movie shows my Oak Hills Spirit II
rig on 40m - the first few seconds are no signal, just band noise (You can acually see the frequency
response of the RX and built in four-pole audio filter on this rig here!).
The passband center of the whole RX
chain appears to be about 900 Hz - that is as the receiver is presently
aligned.
After the first few seconds of the movie I tune 'across', and then on to a CW signal
and you can see it rise and fall in the passband of the RX.
The
yellow reference line is 900Hz.
What a great and free tool. Thanks to
KD5HIO and AE4JY for a terrific addon to the shack.
