[MRCA] Moose & Squirrel Birthday Party

[Ray Fantini]

The R&S stuff looks great, I had a couple R&S television transmitters that I took care of with one being a analog air cooled 1kW and a 5 kW DTV liquid cooled that were recently scraped out with the death of analog television and the band migration but in the ten or fifteen years of constant operation of the DTV transmitter did not have that many problems and when we did have things like a bad amplifier assembly would pull it out and drive over to just outside of Baltimore to the R&S facilities and swap it for another.
All their broadcast transmitters use multipole amplifiers that are parallel so loss of one or two amplifiers only result in reduced power but not going off the air, hot swapping is always fun!
The thing I did not like about R&S was that every part from the screws up was all EU only stuff, all the connectors beyond the BNC or XLR were EU, all plumbing fittings for the cooling system were weird EU sizes and flanges and when things like circulating pumps failed you had to order from the company the unique four bolt flange EU water pumps that were around three thousand dollars.
Also, both transmitters had to be provided 400 volts three phase power, not US standard 480 or 208 but 400 volts AC so we had to have huge transformers to convert 208 three phases to 400 for each transmitter. The transmitters are long gone but still have the huge heavy transformers on the floor of the transmitter shack that won’t go away. Anybody want a three phase 208 to 400 volt transformer? You can have it for free if you come pick it up.

Thanks to Al, our FEARLESS LEADER! For running the net and for everyone who helped create such a great net to get to exercise our toys. Everyone should reply to Al to fill in your details of the rigs for posterity.

I was hoping to QSO with Ulrich, but alas we were too close for good copy. In his honor, I operated using two Rohde and Schwarz pieces of equipment on the net today, the manpack was an R&S M3TR manpack operating into an R&S FK859 antenna coupler into a 43’ vertical.

Let me know if there is anything I should change or add.  Might be interesting to document some of the interesting rigs.
By my count, we had 9 PRC-47's.

N1UL - ULRICH ROHDE (Taught some of us a lot about radio.) showed up in the post net and caused a pileup.  He was  on one of his own radios from Upper Saddle River, NJ.

Thanks to everyone who made this a success.
