[TowerTalk] Comtek PVS-2 80m Box with malfunction

[Comtek Systems]

Hello Rag,
 
We have received your posting on TowerTalk and are replying directly, as well as to the reflector, to be certain that you receive a
response. We we have searched our entire e-mail and spam filter system have not received an e-mail regarding your trouble.
 
Here is a troubleshooting list to check on your system.
 
1) Re-check that each antenna and antenna feedline are good. Use of an analyzer at each antenna feedpoint is recommended. Each
antenna should have very similar characteristics.
 
2) Re-check that your 4 conductor control cable does not have a broken conductor. A continuity or voltage test for each conductor is
required. This cannot be done with the units connected to the control cable.
 
3) The number sequence on the control cable connections are different on each unit. On the Relay unit the numeral connections are
labeled 3 2 1 G from left to right , however, on the Control unit the terminals are labeled G 1 2 3 from left to right. Please check
to be certain that the same colors are connected to the same numbered screw at each unit. Incorrect color code connection is the
most common cause for the trouble you are having. Control voltage should be arriving at the Relay unit end of the control cable
corresponding to your color code at the Control unit connections. 
 
4) Swap the antenna feedline connections at the Relay unit ( Antenna 1 to "Ant 2" port and Antenna 2 to "Ant 1" port). If the
malfunction changes to a different switch position, then the feedline or antenna are the problem. If the malfunction stays on the
same switch position, then there may be a problem with the relay unit, if all previous troubleshooting has determined that there are
no external troubles found. If this is the case, then the unit may require service. Contact us for details.

Hi
I have bougth a new Comtek PVS-2 80m box with malfunction in one direction.
This is connected to two similar GP's for 80m + a MFJ 50 ohm dummy load.
When I switch to direction 1 I get high SWR(ant 1 connection), and direction
3 is ok (antenna 2 conntection).
Maybe the relay don't switch properly?
I have the export unit for 240VAC to 12VDC.
I have checked the wiring and it is ok.
I have email comtek System, but no reply.
Anyone have a same experience?
