OK. So why did we call it a 125? Was that the original 25set name?

It's like splitting hairs really. The 25 and the 77 were not identical radios according to this site:

Rob,
If you're a 524 guy then we get to ask you about 46 sets. ![]() Easier if you just worked on a CLAK like a normal 052. JD

This is what I know... which may be very little.. but I certainly have a few nights carrying around both the 25 and 77 set man pack boat anchors...
I always knew the PRC 25 set was an older version, and the ANPRC 77 set was newer. It was reported to have had updated electronics, and a breather mounted on the battery cover. Other than looking at the tag where the serial number was (which stated 25 or 77 set) the breather was a sign of the .... 77 set. For the RRB function, in a vehicle, the dual installation system either 2x 524s or 2x841s (77s in trays) you needed a thing called a 2299 box which, when engaged on RRB allowed the radio net to be rebrodcast. That was a couple of years back so I may be a little rusty on some of the more complex terms like RT841/77PRC etc but I will never forget that radio..... I'll see if I can dig up some pictures.... For all its worth Craig Tanner |

The '77 manpack harness fits nicely over the passenger seat of the M38A1 jeep. Tilt the seatback and judiciously arrange the pressure points. The 10' antenna mounting unit cable (forget the name) normally connecting the AMU to the RT524 also connects to the '77. I prefered the handset of the '77 set hitched onto the '524 versus the headset and mike combination. Fewer loose pieces and it used one headset plug-in vs two. Or, keep the '524 on one freq' and monitor another on the '77 with its 10' antenna.

the 25 is the older version of the 77.
the 77 was solid state and the 25 had to have the crystals tuned in. in the 70s all the 25s were trasferd overseas and sold leaving the 77s for the US military the pwr supply and the 77 is the grc-160 its all part of the VRC-1 system
