Title: Original Viking Ranger Schematic Post by: ns7h on July 31, 2023, 06:43:48 PM I picked up a Viking ranger that does not have the grid block keying and modulator screen modifications. I cannot find the earliest version of this transmitter schematic to match my version of the transmitter. I want to restore to original specs, then choose to install select mods. I have found several good sites for restoration, but I still haven't found the pre Ranger 1 and Ranger 2 schematic.
Any help is appreciated. NS7H Title: Re: Original Viking Ranger Schematic Post by: Pete, WA2CWA on July 31, 2023, 08:08:56 PM Both were easy to find using Google. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
