I did a google search on ' SRFU18 ' and came up with a couple of links that might take you back 5 years or so...

I have a Lucent SRFU18 amp module that has been converted for 23cm. Anybody using one? If so, what are you using as a 24v PSU? I cannot find any info on its current draw. I would be also interested in how you are managing the antenna changeover switching.

whatever i can find in my power supply box to suit but one that i can tweek to 26 volt as i suspect that is the correct rail voltage for the amp
current wise around 6-8 amp i will check the transistor specs for Vcc to be sure
perhaps a sequencer from w6pql ? to work the relays and delay
and a what i have on hand is a pair of ducommun sealed rf relays (ex something) with mini uhf connectors
not much info otherwise on the net but ill keep searching.
ps
did you get the ft 847 working ? as i managed to get mine partially working but gave up in the end and designated it to the bin.
