Steve Haney's a great guy to deal with and I've also bought bits and pieces from American Milspec in the past with no problems (

That RT-524 looks pretty much complete. Demil procedures varied, but the last bunch sold in large quantities (Wisconsin Army National Guard was the origin of a lot of them) had the A2000 module removed and usually the transmit tubes too. Unfortunately they also tended to remove the back half of the radio, toss the shielding, then reassemble the back half of the radio to the front less than carefully, which led to a bunch of other problems when they spun the dials haphazardly just so the halves could mate half-assedly.
Also, I've come across a bunch of complete ones from surplus and Ebay and the like with the same problem: i.e., you turn it on, the squelch won't quiet in any setting you care to pick, and the radio won't transmit. Easy solution:
1) Open it up
2) While you're in there, flip it upside down, flip the leftmost module up and set the XMODE--NORMAL switch to NORMAL (it'll inevitably be on XMODE)
3) Operate the HIGH-LOW-RESET swtich on the front panel and look behind the front panel to see what it's supposed to do -- i.e., reset two standard-type circuit breakers when turned to RESET.
4) One of the circuit breakers won't be resetting. Get yourself a nice, long, thin blade screwdriver and CAREFULLY reset the circuit-breaker with it until it clicks hard over to the same side as the one that actually DID reset with the RESET switch (as in, the tops of the circuit-breaker toggles should be pointing at one-another.).
5) Put it all back together and voila! Working RT-524.
That circuit-breaker pops when hooked up via the CX-4722 control cable to a bad MX-6707 or MX-2799 AMU. Before hooking the radio up, check to make sure your MX-6707 freq range selector knob turns freely or you'll be repeating the pull-the-covers-reset-the-breaker deal sooner than you'd care to. Both AMU types get full of water but out of the two -- the MX-6707 seems the worst. You can cheat and get yourself the AS-3900A antenna system from a SINCGARS and dispense with the MX-6707 and associated CX-4722 cable entirely -- though from what I remember the average match with the AS-3900A isn't as good as with the MX-6707/ AS-1729 setup.
