Hello to the list,
I recently purchased an original unmodified Ranger 1, a later version with the bias supply and will soon be restoring it.
I was wondering if anyone on the list might happen to have a soft copy of the PTT mod which used a 12V relay. I saw mention of this PTT arrangement in the archives but couldnt locate a link for it.
Also since I am not entirely familiar with this rig yet are there any simple improvements that could be made to it without any radical circuit changes? I have seen the turbo ranger mod and really dont want to go there with it. I'd prefer to keep it closer to stock.
I am aware of the 18k resistor which need to be changed to a higher wattage which i will do. I will also replace the electrolytics which look pretty scary and the paper caps.
Thanks in advance for any info,
73,
Joe
