Here is a puzzle.
Several of us around here regularly connect to a particular remote radio site using RRC-1258's. K3/0's at control sites, K3's at the remote site.
Recently some of the group have found they can still connect, but cannot control the remote radios at this site. Meanwhile the rest of us can still connect and run the remote radios fine.
The symptom is: Turn on power to the K3/0 at the control site, and the connection "beep" is heard. The remote K3 turns on. The control K3/0 shows the remote radio's frequency, and audio is heard. But adjusting the AF gain at the K3/0 does not change the audio volume, and tuning the K3/0 VFO does not change the remote radio's tuned frequency. Band change, mode change, etc. does not work. Turning off the control K3/0 turns off power to the remote K3.
Again, this has occurred suddenly and affects some, but not all, of the remote operators. The operators that it does affect can still use their RRC's and K3/0's to connect to other remote sites as before.
Has anyone seen this kind of partial connectivity -- can connect and can receive some data (remote audio and VFO setting) but can't control anything? Any help gratefully appreciated!
