Speaking of PRC-70, I have three of them and some NOS boards. I also have two power amps for them. I do not know if the amps ever went into production, but Jane’s does show it. 73 – Mike

looks like a Raytheon attempt to produce a AN/PRC-104, The AN/PRC-70 about the same but that goes way back and the 74 before that. Harris, Collins and Sunair produced a bunch of stuff around the same time but don't think any of that ever caught on like the PRC-104 did.
Speaking of the PRC-70, is it just me or has anyone else noticed how much they dropped in value? Everyone now want the "Cool" new Harris sets that don't work?

Whazzit?
2-11 mc AM/SSB/CW transceiver, 1965 vintage?, 12v battery
Transistor, Synthesized, 1 kc increments (1 mc master oscillator)
455kc Collins filters. Lots of double-balanced mixers.
Raytheon logo on one circuit board but not elsewhere.
Some of the photos are just from trying to use the camera as a magnifying glass.
It looks like the front panel ought to fold down, but connections to the LOAD control prevent that - I'm still trying to figure out how to get deeper and trace some connections.
I couldn't remove the cover atop the slug-tuned coils - I lifted and peeked and it looks like the 1mc bandswitch. I can't figure out that nearby module coupled to it by the chain and with leads from the LOAD switch.
Handset connector is MC10-14-6PN - a second connector was pulled and extender wires added.
A cable/BNC connector has been added which runs back to the 455kc IF module.
The antenna connection has been bodged up a bit. The battery connector was replaced by a 3-wire terminal strip.
The 2N1899 output transistor is rated 125w dissipation.
It looks like there may be an internal switching p/s module (left rear of chassis)?
Please email info or leads
Thanks,
