The only thing good about the RT-524 is the "Red Flag" channels  - - so we could hop around all over the world. My best distance here from "Chickenland" is Colorado. We try to monitor anytime we are in the Ops Center. Why do we have two sets? Ans: One is broke all the time.

Hi Guys - Maybe we were just lucky, but in my experience with the RT-524 in the Navy they were very reliable.  Not covered with mud in the back of a jeep but in our 3 PT boats (PTF's), 3 Patrol Gunboats and command HQ.  They were very reliable being powered by the vessel's big 28 volt battery charged by a 15 KW diesel genny.  I was the division Electronic Materiel (maintenance) Officer as a collateral duty for 3 years and don't recall ever having one fail and they were on constantly. One thing you needed to do was routine checks of the AS-1729 antenna base units which were prone to water leakage.  Silicone!
 
We also had ARC-27's and ARC-94's (Collins 618T) aboard the PTF's and those both failed regularly, often in the process of killing their shock mounts from the pounding.  They were off to the local Naval Air Station radio shop for repairs.  The RT-524 (VRC-46) could take the beating.  Here's a pic of those radios in the PTF radio room.  Clean, dry but very "energetic" while underway.  https://www.n6cc.com/wp-content/uploads/PTF17-Radio-Room_NEW.jpg

Never had to wonder if a VRC-12 was going to achieve a tuning solution or not and have to wait until the light comes on before transmitting, or have huge power sources and cables to make it operate.
I worked with maybe two T-195 transmitters and you came to their defense but have worked on maybe a dozen or so RT-524 and 246 sets and unlike the T-195 they are way lighter but most important of all  are easy to work on. Just try running a T-195 out of its case, but the 524 works all day long with the top or bottom removed. Biggest issue I have found on the 524/246 sets are the band switch contacts on the little plug in cards in the receivers front end will get dirty and degrade performance but beyond that and having to repair when they have been demiled it's a somewhat trouble free radio or at least I would prefer to work on ten VRC-12 radios then one GRC-19.
Will admit that the RT-246 that I use to have in the mutt had failed several times in the field after it got hot but did finally get that sorted and at the end of the day replaced that with a 524 because I wanted a internal speaker but in the last couple years now that radio has been working without issue. The biggest problem is getting others out to events and active on 51.0
We did have a lot of activity on 51.0 at Gilbert during the MRCA show and some at Hagerstown but most of the time the radio remains silent.

  Might as well put that RT-524 on my same "stupid"  list. It has a MTBF of 8 to 10 hours. Wasnt even reliable when it was installed in Comm Hut instead of a vehicle.  But add "who needs a FM set that takes two people to lift it.
