[AMRadio] Right angle drives and the signal hound

[Bernie Doran]

 I have been searching for a source of good right angle drives and seem to 
have found one at Torque Transmission, an Ohio co.  ordered two of the 
double output shaft  drives after talking to them.  I need to gang two 
vacuum variable caps for a P-P amplifier and these should work. Not cheap, 
about $76 each.

The signal hound looks interesting but seems to be more an item of test 
equipment and not really usable as a receiver as are some of the  SDR  guys. 
The signal hound shows +20dBm as the max allowable signal. and also shows 
sensitivaty as better than -160 dBm ! They do not say at what bandwidth, but 
it has to be at the tightest of 1/10 of a cycle BW.   that is sure not 
usable for any communication.    They also alude to what I used to call 
birdies.   That is a problem with the SDR-IQ, as is the horrible audio out 
of that thing.  It does make a nice band scope.
