For those of us with time on their hands, SARC has just published the Sep-Oct edition of their Communicator newsletter. It's another 100+ pages of interesting stuff, very impressive.
For nanoVNA owners, this edition includes another installment in a series of articles by Arie Kleingeld PA3A on using the nano for various measurements. The first one was in the Jan-Feb 2021 issue.
All issues are available at: https://ve7sar.blogspot.com/search/label...mmunicator

THE UBIQUITOUS 6146 |

These days everything is solid state, but some of us became hams when vacuum tubes were everywhere. No other tube has powered more ham rigs than the 6146 & its cousins:
6146A: improved heater
6146B: completely redesigned, not interchangable with earlier ones
6146W: ruggedized military version
6883A/B: 12V heaters.
RCA introduced the 6146 in 1952, and they are still going strong in lots of vintage ham rigs.
When I first got licensed in 1968, the UNB ham club had the big Heathkit twins - Mohawk RX & Marauder TX. The Marauder used two 6146s for 180 watts PEP. They were great rigs, a real pleasure to operate.
My first TX was a little EICO 723 which had a 6DQ6 PA, giving 60 watts on CW. It's big brother was the 720, which had a single 6146 for 90 watts CW or AM. After I graduated & got a job I splurged for a Heathkit SB-102, which had: 2 - 6146s.
I've been searching for parts to recreate my original station. I didn't think I'd ever find an EICO 723 so when I saw a reasonably-priced restorable 720 I bought it. Of course immediately thereafter, I saw a 723 so now I have both! I'll be listing the 720 one of these days.
Here's what they look like:
If you want to buy one, RF Parts has new Chinese-built 6146Bs for about $60US. Also many NOS & used/tested ones listed on eBay & several online stores.
Recently I saw a thread on QRZ.com where people were posting lists of rigs that used the 6146. It's a long list.
