ARRL June VHF Contest 2019

I’ll be operating from EM23jd the whole contest with no sleep and 2 coffee pots going. I have spent the last 4 months rebuilding the whole antenna/tower system and fine tuning it with new LDF5 feed lines and flat SWR on all bands. I’ll be working 4 bands ( 50/144/432/1296) instead of 5. The 222 Transverter decided it wanted to give up during testing this week so I lost a band and can not get a replacement in time. I only know of 2 Hams that work contest periodically from EM23 and......

Tower Up to 57 feet!

The Rohn 25 VHF/UHF tower has been sitting at 37 feet for a while as I build the station up. My Son had a chance to come out and help get it to the 57′ mark this weekend. So now with the hazer and the 24′ two inch mast the 1296 yagi should be sitting at the 80 foot mark with each band dropping down a little more till the 6 Meter yagi at bottom. When done I should be on 5 bands and ready for June 2019 VHF Contest…. I hope........

VHF 48 Volt Power SUpply

SSPA 48 Volt 44 Amp Power Supply This page should document the build of a 6M/50Mhz kilowatt SSPA Harris amp. The plan is to build a cabinet out of a metal File cabinet on wheels that looks nice and clean to house a single PSU for all of the SSPA amps in the works. But first to get a 6M amp built and running. I have tube HF and 2M amps now, but will be upgrading to SSPA amps for all the bands to get full legal limits on all bands.  While......

Origin of the Name "HAM" for Amateur Radio Operators

If you search the Web for the origin of the term “HAM” for radio amateurs, you will find two or three accounts that are evidently most believed. However, this version seems to be the most credible. It was provided to me by a very active and accomplished HAM, Mr. Cornell D., who is not given to propagating bad information. I tried unsuccessfully to locate an original version of the “Florida Skip Magazine” from 1959. If anyone has a copy that can provide a scan of the article, it would be a great......

How to Perfectly Clean Wires in Minutes!!!

Here is an old ham radio operators trick for cleaning wires for soldering that are old and corroded. It is hard to find this technique printed anywhere! I am a ham, N5ITO. Normally, if you strip a wire, and see it is corroded, there is not much you can do to restore it’s shiny new conductive properties. There is scraping and scratching which comes to mind, but you’ll never get it to the solderable slickness it once was long ago. After laboring and fretting over the corroded pieces of wire for a......
