Ed, Make sure that you put the RV7 switch in the correct position(s). If you did, then proceed.
If you didn't even have lights, I would check the bulb. Take it out and make sure it lights on 12 volts from a small power supply. If the bulb lights, then I would look at the jones socket on the TR7 to see that it has the correct voltages present. Look at the schematic of the RV7 to see which socket pins has the +12 volts and ground. 73 Ron WD8SBB --- On Tue, 7/19/11, rfch...@verizon.net <rfch...@verizon.net> wrote: From: rfch...@verizon.net <rfch...@verizon.net> Subject: [Drakelist] RV-7 External VFO Problem To: drakelist@zerobeat.net Date: Tuesday, July 19, 2011, 6:57 PM A buddy of mine who knew that I was going to a hamfest this past Sunday asked me to pick up an RV-7 external VFO for use with his TR-7. I saw one at an agreeable price, was assured by the seller that it was in working condition, and I purchased the RV-7. When I connected it to my TR-7A is was as "dead as a doornail!" Absolutely nothing. Anyone have any suggestions before I start to really tear into the RV-7? I checked the obvious, eg. connections inside the Jones plug, looked carefully for any broken wires or missing componenents, etc. Any help would be appreciated.
