[MRCA] Angry 5 Revival (change of subject, sort of)

[Ray Fantini]

I have always referred to them as “Angry Five” don’t know if that’s correct or not. Much controversy around that radio, have been told they were used as “Gas Net warning “ receivers, as “Operational Net warning “ to broadcast they daily bombing targets and as entertainment receivers? Years ago I had one that I built a battery pack for and ran it for a long time just on D cells and a B battery.  Its fun also to have a radio who’s multi voltage power supply is just as big as the radio itself! Think that radio would be a good candidate for solid stating the vibrators and trying it that way.
Think that it goes back to all those radios of the late forties and early fifties and would look good paired with a GRC-19 (T-195/R-392) set up but unlike all that other way obsolete by the seventies RT-67,68 or RT-70 stuff that receiver was still in service and somehow appears in MSC-31/32 communications centers as a axillary receiver along with the VRC-12 stuff.
It would look real good on the back of a M-38

Not to pick nits but “angry” applied to AN/GRY- accessories, “Jerk” applied to AN/GRC-, and “prick” applied to AN/PRC-.
Of course this was the Army, and I was AF, so I am prepared to take any and all heat for these statements.

I picked up this receiver at the spring Nearfest meet in NH, I thought it looked nifty and rolled the dice it might actually work.  I powered it up with 24v and after a brief pause it came to life, I tuned around and was listening to several stations, my joy was short lived, after 20 minutes of bliss a fuse popped.

I asked a friend if he was willing to see what happened and the initial failure was a buffer capacitor on the main winding had shorted to ground, he said I was lucky it didn't take out the winding.  He ended up changing out multiple if not all capacitors that tested bad, how this even worked at all is amazing, the selenium components were also replaced.  After an alignment it now outperforms the stated rx sensitivity and it is working great.  The angry 5 now has a permanent home in the shack with the other green monsters, a great big thanks to my friend for all his hard work bringing this back to life.
