I have three voting receivers on a six meter split site system. Two of the lowband receivers are located together at the receiver site but are on different antennas at different levels each with their own voter. The third lowband receiver is located some 13 miles away which is linked to the receiver site by a UHF link.
I have problem with the system locking up at times and I have to wait for the voter to time out. It doesn't seem to happend all the time. I haven't been able to put my figure on what is causing the problem yet. I thought maybe someone here might have had the samething happen.
System information is as follows
Everything on the system is Motorola Micor
Voters are set to 0dbm
Spectra Tac tone is set for -13dbm
Lowband receivers 51.xxx are using PL 127.3
UHF link receiver is 423.xxx using a PL 107.3
UHF Link transmitter (30watts Pl 131.8) 445.xxx (located at the receiver site) this sends the voted audio to the Lowband transmitter.
This problem seems to occur when a conversation is between the local lowband receiver and the UHF linked lowband receiver. If I shut local lowband receivers down I don't have the problem or if I shut down the UHF linked lowband receiver I don't have the problem. Its just when all the receiver voters are on that the problem occurs
Thanks for any help in advance

Re: Spectra Tac
By locking up, do you mean the system stays keyed after the user has released?
And for review, you have site A with the voter with three sqm's, two rcvrs on the same freq (that's a question for another day), a UHF rcvr, and a UHF xmitter. At site B you have a low band rcvr linked to the voter through a UHF xmitter, and a lowband xmitter linked to the voter through a UHF rcvr. At site B, the Micor will in cabinet repeat if the voter, or the UHF link are shutdown.
When the system locks up, what does the front of the voter tell you? Which site is being voted?

Your review is almostly correct. There are three sites.
Site A. has the two lowband receivers and the link UHF receiver (site b's lowband receiver) and the voted audio link UHF transmitter that goes to Site C which has the Lowband Transmitter. The UHF Transmitter has in Cabinet repeat
Site B. has the Lowband reciever linked to a UHF transmitter that links to Site A
Site C. has Lowband the lowband Transmitter which is linked from site A's UHF Transmitter.
I have to get out to Site A and check as to which receiver is voted when this happends. Also I did check and all the Squims are the same verisons.
Thanks

Re: Spectra Tac
I have had this happen B4. Voice peaks were going over 0 dBm....causing guard tone issues and the locked comparator until she timed out after 15 seconds or so.....I lowered my audio levels and problem went away.
