I was wondering the same... are you thinking a bad duplexers? or maybe re-tuning? >>> "K5IN" <[email protected]> 7/10/2009 10:13 AM >>> Sounds like a temperature related issue. You might recheck the duplexers and even knock on their housing while testing. I am no expert but am only throwing out suggestions.

Just replaced a damaged mast for our VHF repeater. Went with a 4-bay dipole as a replacement, along with switching out the old coax with 1/2" hardline. Everything else stayed the same, VXR-7000 and internal duplexer. All worked well after a final check, until night came along, when it seems to possible to a casulty of desense? In base mode, tx and rx are wonderful, but when switched to repeater mode as soon as it rx's and attempts to transmit, it cut's itself out. About a one second in, out, back in, out, etc. Not sure what happened but around mid-day it started working fine again, then last night started acting up again. Any thoughts? suggestions? Did recheck all connections from antenna down and everything is tight.
