boys...
yesterday I had some extra time in the shack and decided to fire up
one of the old Triton IVs I have .
I also fired up the Argonaut V.
Now, using the same antenna.
The noise level on the Argonaut V was running between S-5 and S-9
On the trition, very little S-meter movement was seen and it was just
not that noisy
so I decided to test the receiver's sensitivity with the HP signal
generator. I injected the signal in place of the antennas
At 50uV I got S-9 on both rigs. At 1uV I could detect the signal. At .
5uV I could still hear the signal from the generator. Although the
triton had a harder time hearing at that level.
Applying the attn on the Argonaut V, reduces the noise level, but as
suspected reduces the signal strength of in coming signals, too
So bottom line? Why is the Argonaut V so much noisier than the old
Triton?
