Re: [VHFcontesting] [VHF] Warmup Drift Of Ukranian , UT5JCW, 222 MHz Transverters & Possible Use With FT-8 (score: 1): Author: JamesDuffey <jamesduffey@comcast.net>; Date: Fri, 16 Apr 2021 09:03:55 -0600; Pete - W7QQ and I looked at about a half dozen of the Transverters Store (Ukrainian) 222MHz transverters a few years back. One thing that we noticed was that the drift we measured, while similar to t; /archives//html/VHFcontesting/2021-04/msg00035.html (10,991 bytes)

Did Steve check the old DIP one or the new TCXO one? - Duf; /archives//html/VHFcontesting/2021-04/msg00037.html (10,215 bytes)
