Re: [Repeater-Builder] micor desense problem
The first thing I would do is change the PA out with another to make sure that it is not a duplexer/filtering problem. Also, I presume you have decent cabling between the TX and duplexer/ RX and duplexer? Andy KC2GOW __Do You Yahoo!?Tired of spam? Yahoo!

[Repeater-Builder] micor desense problem
Would appreciate any feed back concerning a VHF non-unified chasis Micor repeater. The rcvr. is apparently being desensed by the an unstable PA. Bypassing the PA eliminates the desense. One suggestion recieved was to check /replace the Tantalum bypass caps in the PA The PA is a TLD8453A. A review of the manual and visual loook at the PA bd. does not indicate any Tantalum bypass caps being installed. Should the bypass caps in the power supply be suspect as well?? I can't ID any Tantalums there either. Can anyone give me the Cap nos. that I should suspect of being defective so I can cross reference them to the manual, or any other suggestions re: correcting the problem short of getting a new repeater. Any/all help will be appreciated. 73's Doug Yahoo!
