We’ll meet two (2) days before Field Day as usual, in the back Party Room at Scott’s hamburgers in downtown Bixby, 7 to 8:15PM (because they close at 8). Program will be Your Show and Tell, and if time permits, some more Field Day Rules (see ARL dot org 2026 Field Day Packet), and then…

Dr Mark and Rosemary, NM0D & KE5CMS, hosted the Evergreen Church Group (EverGreenCG . org) at their hilltop venue Saturday morning 06.13. It’s a great place for Field Day type operations with a large pond (reflecting ground) and plenty of trees for antenna support and shade. That’s Mark K5LGS in blue. Kenny KJ5EKW arrived early…

Tom WA5MAZ, having renewed his license after a few decades, has also renewed his SBE-34 HF rig by replacing a couple of electrolytic capacitors, one of which has begun to exude white stuff. The SBE 34 came out in late 1960s, well before the Kenwood 520 and Yaesu 101. The SBE was all tubes and…

Attending were (Left to Right) Kenny KJ5EKW, Jon W5JCN, Mike KI5YX, Tom WA5MAZ, and newly licensed Ham Anthony KJ5PUZ who has a Tiny SA spectrum analyzer in his hand, a similar and much more fun to use device that uses the same basic parts as a VNA, a wideband sweep generator and matched receiver. 2…

Field Day isn’t that far off, only another 6 weeks to make sure the generator works and the LifePo batt is charged. Everybody at the meeting had the rules (1.4 MB ‘Field Day 2026 Packet’ from the ARL) and we discussed whether to go to one of the local clubs and help out their Class…

Tom WA5MAZ (ex KJ5NMH) is making sure his old Motorolas are up to spec, and bot this Gertsch FM deviation meter in Muskogee for 75 bucks. It’s old, full of tubes, and needs to be at a particular temp to be in spec, so comes with A Mercury Thermometer that contains Hg. It’s a normal…

Last year at Green Country, I thought there were a lot of books, old Radio Amateur’s Handbooks and Callbooks etc. This year I noticed quite a few Kenwood 520 HF rigs (plain 5 band 520, the 6 b 520S, and economy model 520SE without 12V capability and lacking plugs for the 10 Watt 6M or…

Tom WA5MAZ (ex KJ5NMH) brought in some old Motorola stuff again, a tube type portable 2M rig from back before you were born. He made this 90V power supply to test the tiny jelly bean size tubes to find (surprisingly) they all worked. Listen on 146.91 Wed and Friday at 7 to hear the old…

Tom NMH has switched back to his old callsign, WA5MAZ from the mid 1960s. At the Thurs 03.26 meeting he brought in two (2) Motorola handy t – well, back then they were more like lunch boxes, the one from 1958 mostly transistors (except driver and final tubes – little ones, 1W out), and the…

We were going to compare RX sensitivity on Chinese H/Ts, but instead, we spent most of the hour measuring TX output and using a Spectrum Analyzer (Tiny SA on Ebay for $68) to check for spurious output. Shown above is an anomaly, second, third, and fourth harmonics that weren’t there. Two Baofeng UV5Rs (the x3…
