Gus, Glad you got the bad RCA chip found and replaced. You might want to get a back up, as RCA is long out of the semiconductor business, but those chips do turn up in Surplus sales. -Stuart K5KVH
DeOxit combines the cleaner, deoxide agent, and contact lubricant into one application. Cramolin, was an older formulation, that needs other agents to equal DeOxit as I understand the formulas. A bur
Yes, Rick. You can disconnect a big red wire that puts voltage on the finals transistors. Tape it up. Then you find the coax jumper that connects the filters to the finals. Move the end of the jumper
Sounds like the filter input that had 8 diodes open took a transient hit. It is good insurance to physically disconnect your rigs from any outdoor antennas when not in use. Storms can blow up suddenl
Most any SWR meter is useful on 6m as a relative instrument. In SWR measurement, it does not matter as much what your Absolute SWR is, as can you find a minimum SWR somewhere in the band? Thus, even
The "hallowed" Bird Watt meters and most commercial watt meters are only good plus or minus 5 per cent. But, that is well within any commercial or ham needs. Stuart Rohre K5KVH
How good is your coax? Maybe you have some problem connections when used at 6m if you are not getting even relative readings. My TT 1225 was well agreeing with Bird instruments at even 2 meters. A ne
Interesting that some 1225's work better at extreme range than others. I wonder if there were some parts substitutions by Ten Tec over the years of production? I have had mine for many years. I think
Rick, you might try unravling the Q tip to make a smaller diameter one. Another idea we used on tight relay contacts, was soak a piece of typing bond paper in the cleaning solution, and then work it
There was a relay cleaner suitable for the coaxial power jacks used on Ten Tec Scout filters, made by General Cement electronics chemicals plant in USA. GC products were very common in electronics di
Yes indeed, WD 40 is "water displacement compound formula 40" It is NOT a lubricant! Most misused chemical besides alcohol and tobacco! It soon turns to gunk. DeOxit is for electronic contact cleanin
DeOxit is to be used with a swab or toothpick to apply it. That little will do its work. You should not get any on wafers or you are applying it wrongly. You should not spray things willy nilly such
These types of problems usually indicate that there is RF leaking back to any any transceiver he might try, because his antenna is too close to the shack, especially if shack is on second floor. One
For those faced with replacing filter capacitors that are leaded. If you are concerned you are going to lift traces, simply cut off the leads of the old caps, leaving enough of a stub of wire on the
Some Yaecomwoods do suffer from RF entering the rig. MOST ANY rig will if you have a bad shield connection on coax jumper, or have rig too close to the antenna, (second floor shack), and there are ma
Carter, An easy test for you. If you take an ohmeter from the shield of the mike cable at the base of the mike or where ever you can access it, and then touch the other probe to the chassis of the ra
Carter, although the two mikes having the problem probably means two different mike cables, do check that the mic connector pin that is supposed to be shield ground DOES go to the chassis of the radi
Jim, don't we all use Flukes now? :-) I do have several at home and work. I was remembering a discussion of a rig fault where the pin intended for grounding, had not been grounded at the radio connec
