Title: Ranger Help... Post by: kx9dk on December 30, 2005, 02:37:15 PM I'm in the process of rebuilding an early version Ranger. I got the RF section working except for 40 meters where the most grid drive I can get is around 1.5 ma. I get plenty of grid current on all the other bands (up to 5 ma). Any Ranger users out there run into this or know where the problem might be?
Thanks Dave KX9DK Title: Re: Ranger Help... Post by: W2INR on December 30, 2005, 04:36:10 PM Hi Dave
Check the condition and the values of the resistors on the Bandswitch. If I remember correctly the first section ( closest to the front of the rig) is the section that switches the grids. When I had that problem I found a resistor had changed value. Good luck Gary Title: Re: Ranger Help... Post by: kx9dk on December 30, 2005, 08:05:42 PM Gary,
Thanks Gary. The first resistor I checked (R8) was bad (open). Supposed to be 68K. I got lucky and found one in the junk box. Works great now with plenty of grid drive on all bands. Thanks for pointing me in the right direction. Now I just need to get the audio section cleaned up and I should be able to put the rig on the air. Dave KX9DK Title: Re: Ranger Help...
