AN-PRC-74_description_2008.pdf

68 A big hello once again as I open the doors to the Valve and Vintage (V Non-US made back-pack HF USB/CW/AM transceiver. Designed by MBLE as the BDR-500 series, PRC- 1012 is the NATO designation for that equipment. The PRC-1012 is similar in design, technology and purpose to the US PRC-74. Apparently, it lagged the 74s development by about fi ve years but incorporated some improvements which allowed more fl exibility. Two versions of the BDR-500 series are known, the fi rst, BDR-510, tunes 2- 12MHz in 1kHz steps with an r.f. power output of 10W. The later improved BDR-550 tunes 2-18MHz in 100Hz steps, with an r.f. power output of 4 or 15W. Luckily, the set I acquired is fully working and very nice to use. Again, come a sunny day I intend to try the set out in the fi eld with a decent antenna! The photographs in Fig. 5 and 6 show the relative sizes of the three units. And Finally Well thats about it for this stint in the V&V shop. I hope youve enjoyed the selection I have bought you and there are more pictures at g4bxd As always I can be contacted directly at: 62 Cobden Street, Kidderminster, Worcestershire DY11 6RP, or via E-mail at military1944 Cheerio for now!
