[TenTec] Ten Tec 565 with Tuner

[W5SJL Amos Favorite]

Thank you guys, I bypassed the Molex connector and the 565 was back to normal.

Wired the 566 unit directly to the I/O backplane board and the occasional problem with driving its  SGC500 also went away.

The cable side, f-mail of both connectors were discolored and corroded.

Replaced the batteries in both transceivers two months ago and also got an improvement in performance.

I agree with Bob's suggestions regarding the Molex connector.  There have been several threads regarding problems with this connector over the years and issues seem to be made worse by any strain on the power cable.

You can find photo instructions for replacing the existing Molex connectors with Anderson Powerpoles at:

Check the 2 pin Molex connector on the radio.  With multiple insertions and the current draw, the tin contacts are noted to heat and loosen and thus not make good contact with the cable contacts.   Look for any discoloring on either connector.  If discoloring exists, replace both male and female connectors.

I'd replace the original connector with PowerPole circuit board mounting connectors and likewise, change the power cable connector.   Also, be sure the radio power cable is connected direct to the power supply and not through a DC Distribution panel or strip.
