Hi all again, AD5IY still trying to get back on the air with my 4B twins. I have not ordered the AC-4R kit yet. I plan on it soon though. I have been looking inside my AC-4 and stuff, which came up with a question for those that have already installed one of the upgrade kits. I have found that on the original AC-4 that D4 is showing short. On my multimeter on the diode check setting, all B5G5 Diodes are reading somewhere around .5v for forward bias/OL for reverse... standard for diodes, but D4 is reading .08v fwd/rev bias... so the top leg of the 650 line is not held ~1v above ground ( by what I understand on the schematic). Weird, I can read drawings, I can understand flow, but I really cannot understand what this would do to the ckt... Nor do I have a multimeter currently at my new location to see if the 650 is actually at 650 or somewhere else... so I wouldn't doubt that will effect the transmitter in some way. I did take the suggestion of one and setup a lightbulb dummy load seeing how I currently do not have my oil can here yet either(not sure when I can get my can here...) but I wanted to check this out and maybe (hopefully soon) get the AC-4R kit before I really try to start transmitting.
So, would repairing this before getting the AC-4R kit be advantagious? or just wait for the kit? and just cause this "pinwheel" of an antenna that I have made is kinda annoying, anyone got any sites for info or ideas on an good hidden antenna for a 2nd floor apartment? Thanks all! Hope to hear ya on the radios when I get them fully up and running!
