Radio Reinvention

The parts arrived for the 6BA6 Rig and I will get back to that jewel.   See the prior post on the parts that arrived for the 6BA6 Rig. While I was waiting for that slow boat from China to deliver some parts for the 6BA6 rig, I reworked the 20M SSB Shirt Pocket Transceiver.   The Shirt Pocket rework was an engineering challenge as you had a built assembly and therefore everything around that had to be fitted into its envelope. This video shows the detail of the parts I had to fabricate.   Reinvented 20M Shirt Pocket SSB Rig     The Case with a trial fit.   WYKSYCDS   ( But not everyone can do what I do!) I could not have undertaken this effort without having both CNC and manual milling machines. While it is true that not every ham has that kind of capability in their shop/shack, that does not mean other creative approaches can be invoked.  Friend N2CQR uses wooden boxes from Michael's and then lines the insides with copper tape. This results in an...

How About Building Something (HABS)?   Update 11-01-2023. The 6BA6 Parts Arrived Some of the parts included a panel meter that ranged from 0 to 30 ma and 2.5 Mhy RF Chokes. Back in the day you could fund these items in any decent electronics store but no more.  The meter was selected because the idle current on the 6BA6 will be about 3ma and at two watts the current should peak to 18ma. (about 2/3 scale). The panel cutout will present some challlenges but with the CNC short work. Pete N6QW Update 10-23-2023. It is indeed shirt pocket size. About two watts out and 60 kHz coverage on 20M.   My daughter took this photo and she asked who else has built a rig this size (mine is 16 cubic inches). I know of three including ZL2BMI and VK3HN and I think a DL station. Likely there are more but if you know of others please email me at my QRZ email address.  Of note this was built in 2011 so soon to be a teenager.  73's Pete N6QW  Update 10-22-2023. Some Clean up!
