[Central-Electronics] 200V driving aCollins 30S1

[George Maier]

Hi Jimmy:

If the Dow Key has spare contacts, you can use them to key the T/R switching
in the 30S-1.  I use my 200V regularly to drive either a 30L-1 or a BTI
LK-2000, and have never had a problem with drive or distortion. I do use a
CE MM-2 scope to monitor the modulation, but you should be able to achieve
similar results by staying with the 200V limits as presented on its scope. 

73 & have fun,

George - W1LSB

Please give me a litle help, the 3 connections on the 30S1 are RF in from
the exciter, Antenna relayand ACL.
The 200 V power out is know problem.  I had plan on using a 115 dowkey relay
on the back of  the 200v.  I do not have ALC so will need to watch mic gain
(I think). Now the antenna relay need help.
I would very much appreciate the forums imput.
Thank You
Jimmy K5CSU
