GRID DIP METER AN/PRM-10 2-400+ Megahertz with Manual 100% Functional

Description

GRID DIP METER AN/PRM-10 with Manual, fully functional and 100% operational. This is without a doubt the battleship of GDO's with incredible performance abilties.
It weighs in at over 15 pounds and still  works as good as the day I purchased  at a USN Surplus auction in 1973 at the Bayonne NJ Naval Yard ! External  dimensions of the steel carrying case are approximately 9" x 11" x 5". The tuning head is permanently connect to the power supply case via a 5 foot power cable. Covers continuously over the range of 2 to  400+ MHZ either as a diode detector or as a signal  generator with fully adjustable signal levels on output or input. Head is remote from the base unit and the coils plug into the head for easy usage.  The PRM-10 is far better than any of the Heathkit series, Eico 710, Millen 90651 or the later China made GDO gear. Photo 5 shows it "on" in signal  generator mode. Also has an internal  1 kilohertz audio oscillator for modulation of the signal, or plain CW, or you can feed in an external  signal, that is switch selectable. Produces a very strong adjustable RF output signal and very good dips when used as a diode detector; just fantastic.  Also has an audio headphone jack output to monitor the signal.  Has 7 individual coils to cover the frequency range from 2 to  400MHZ.
I have been a Ham Radio operator for 52 years and this has served me well, but my designing circuit days are pretty much over so  time to  move on. Includes a copy of the original  technical manual and has schematics, theory of operation, calibration instructions,  and testing/trouble shooting  instructions
. There is a AN/PRM-10 currently on Ebay with an asking price of over ,000!!! The AN/PRM-10 is a really great piece of test equipment, but that's a bit too wildly expensive even for an PRM-10!
