Original Message Subject: Re: [AMRadio] re: no meter reading on Valiant From: "John E. Coleman" <[EMAIL PROTECTED]> To: "'Diane Swynar'" <[EMAIL PROTECTED]> Hi Eddy: Please forward this to the AMReflector for me as I am at work and can receive from the reflector but can't send. Good advice on checking shunts. Another quick check on the meter, that I use all of the time, is to series a 1500 ohm resistor with a 1.5 volt battery placing all in series with the meter to check for defection. With a little ohms law I can come up with the internal resistance and defection range of unknown meters.

Re: [AMRadio] re: no meter reading on Valiant
If anyone needs a meter for a Viking 1 or 2, I have an extra including the shield that I will part with for 25 bucks plus shipping. The case is a bit discolored but the meter works. 73 Jim de W5JO > > "... Output seems good, full power, everything seems to work except the > meter. No meter movement on any setting.

Re: [AMRadio] re: no meter reading on Valiant
Hi Ron, Nice rig! Congrats... Hopefully you haven't blown one of the multiplier resistors that's switched in parallel with your meter...I did that once with a Ranger-1 & destroyed the meter. Check the values of these resistors one by one---if any are open, i.e. infinite resistance, then the meter is cooked for sure (the meter itself is probably rated 5 ma. max). I ended-up doing a "transplant", i,e, took the innards out of one similarly- rated, surplus, off the shelf meter, & dropped it into the original Ranger meter case. Precision work that needs steady hands! But it paid off... Good luck... ~73~ Eddy VE3CUI - VE3XZ > Just picked up a Johnson Valiant.
