[WSWSS] 144.288 Beacon - Techie Help Appreciated!

[Tim Marek]

Hi Gang!

Thanks to all who emailed their technical suggestions=20
on how to tame the beacon transmitter. Great Stuff !!

Things to do include...

1) Hard wire Osc on.
2) Key one of the Buffer amps before the final PA
3) Install a stub to remove unwanted 2nd harmonics.
4) Make sure the Ramsey PA isn't being overdriven.
5) Bypass cap across key line to gnd.

That should be enough to remove the chirp and clicks.=20

After all this is done, I'll recheck the output to see if the=20
waveform has improved.=20

Onward and upward!
