As I recall Jim, he championed the 220, Use it or Lose It campaign. There was a lot of commercial interest in the band in the 70s, probably the same is true now as well. Folks had strong emotions, one way or the other, when it came to Wayne. 73, Julius n2wn --- [EMAIL PROTECTED] wrote: In a

In some ways, 73 represented a different side of Ham Radio. We do owe Wayne gratitude for keeping 220 mHz available for ham use. We always had access to all of the US magazines. Wish it were easier to pick up a copy of none US radio magazines here (then and now) 73, Julius n2wn --- Brian Lloyd

It would depend on your interests. I'd probably stick with QST because it covers more items of interest for me. These being ARRL sponsored contests, national events including legislation/regulation and regional activities. One could argue strongly for CQ magazine for the same reasons. If my bend

Hi Geoff, It seems strange to me that it lingers more on the fringes than moving into the mainstream. If it's been around for 15 or more years, one would think something could have been negotiated regarding any intellectual rights. It certainly sounds interesting based on what I've read. 'Twould

Hi Gian, The H-Mode Mixer (3 transformers) using both SD5000 and FST3125, referred to the TRIAD (W7AAZ, W4ZCB and G3SBI) is reported in the ARRL Book EMRF Design. Perhaps I missed these, been reading more about antennas than Rx design, particularly if it was SDR. Mea Culpa here...
