The M37 isn’t done, but its been awhile since I have gone on a Parks on the Air trip so I loaded my pickup and the M101 and headed to Perry State Park, KS. In keeping with the Korean War era schtick, I brought a Remington typewriter and logged contracts with it. Not really efficient compared with using HAMRS or some logging program, but it worked and it was fun to do. In thinking about how my setup is coming together, it occurred to me that it is similar a RATT Rig (Radio Automatic Tele Type) in purpose, being an HF station at least. I remember the RATT rigs from the 80s/90s as a battalion long range communications setup (Bn <-> BDE), with FM/Wire serving the Bn <-> Battery/Company layer. We didn’t have tactical IP networks back then. I found a website, Rattrig.com, that shows an M37 setup which it pretty neat. I don’t think I will do the shelter part, but I think I can approximate a realistic role for an M37 as an HF station. People do use RTTY (the data transfer mode that RATT Rigs use) on the amateur bands so perhaps I can get a few contacts in that mode in upcoming POTA trips.
