Hey, I had one of those, 1954 I think! It also functioned as a good preamp and added input > selectivity that my 455 KHz IF single conversion HRO-50 really needed on > the higher bands. Mine fed an ARC-5 rx converted for 40m [and with most of the rotor plates on the tuning cap pulled out to spread the band over most of the dial]. I had a pair of ARC-5's TX/RX each for 80, 40, and 20. Before that, I also used a DPDT knife switch. Had one of those too, then "graduated" to a DPDT relay that made a very satisfying "clank" when actuated. Big thing, contact arms looked sort of like spider legs. 73, Fred K6DGW - Northern California Contest Club - CU in the 2010 Cal QSO Party 2-3 Oct 2010 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
