Put a voltmeter on the T-R line from the 811 and confirm that you will
key a POSITIVE DC VOLTAGE (less than 200VDC) to ground. Then put an
ammeter across the T-R line (which should KEY the 811 T-R relay) and
measure the CURRENT required to key the 811 T-R RELAY. If it is < 3A
then the T-R (RELAY) output of the KPA100 should handle it without
complaint.
Hi Tom and all who responded to my query on this. Thanks to you all for
spelling it out in simple terms for me, it is what I needed :-) Chriss,
G3SJJ worked with me off list so I understood exactly what I need to do
(thanks Chris) and it was precisely what you stated above Tom.
For those who might need the info in future, the Linearamp UK 811 has
16v and 190mA at its PTT connection. So, the K2 should work with it
perfectly. I will be attempting this today once I have done a little
work with the filters to finally get my voice sounding right. This
retirement thing is damned hard work but I am finding enough time to get
a few things done that I have been promising myself for years :-)
Thanks again to you all.
73 Ian
