Re: Drake T-4XB rubber feet
I never had a brand new 4 Line but the manual says you need to "snap" in the supplied press fit rubber bumpers. Probably more would have survived if the factory installed them! 73, Gary WB6OGD

Re: Drake T-4XB rubber feet

Re: Drake T-4XB rubber feet
Good morning all: I have never seen the AC-4 6-32 threaded foot ever installed on a 4-line box, new or used, and have owned upwards of 50 of these boxes and accessories over the years. The new 4-line

Re: Drake T-4XB rubber feet
If they're simply stuck on, chances are that they're not original. There are some rubber "nub" feet that came from Drake. They look like the ones that are usually found on the AC-4 (and that is where

Drake T-4XB rubber feet

Re: L7 power amplifier question
Dave, I don't have one here to measure. Research reveals zilch. So I'd just like to know open voltage at the jack and key loop current of an original L7 if anyone happens to know conclusively. Thanks,

Re: successQ multiplier cable
Excellent! Yes, the 455 kHz wiring between the receiver and the multiplier was simple multiconductor cable. It may be shielded but I'd have to take the 2-BQ apart to know for sure. RG-174 is certainly
