[Drakelist] TR-7
I have a TR-7 that has the DDS board installed. It seems to me that it is working in split mode. It receives fine but when you key the MIc the digital display changes and it starts to act as if it is scanning.___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
Re: [Drakelist] TR-7
This is typical behavior when the circuit board contacts need to be cleaned. Open it up and pull, then reseat every plug in board. You might also spray a wee bit of DeOxit on the board contacts. Don't forget to do this to the boards under the horizonal digital display board and the power supply board in the front corner (right side when you're facing the front panel). 73 Lee WB6SSW In a message dated 12/10/2012 6:18:11 A.M.

Re: [Drakelist] TR-7
You did not say what DDS board is being used or how it is hooked up. My first thought when I read this was to ask if you wired your dds vfo to get powr from the 10 volt receive line that goes to zero transmit so that DDS ends up being turned off during transmit. If you have no VFO during transmit the display will do some strange things. More details of your installation would be helpful. Thank you.

[Drakelist] TR-3
Hi Guys ; Considering a fully functional TR-3 from the owner of 15yrs. I've been invited to try it on the air at his shack before I take it. Being a relative newbie to Drake equipment, is there any particular areas to consider with the TR3 other than the obvious and general operating condition? I don't recall anything negative in particular about this vintage radio. I will upgrade the power supply and finals..Anything come to mind? Thanks 73 de n8aft.___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
