Hi Make sure you are using the BNC on the right (J3) when looking at the back for the TX IF in and the one on the left (J2) for the RX IF out. The silk screen is backwards on some of the rear panels and there may be a little label over the original silk screen with the correct information on it. I have two early XVxxx and the silkscreen was backwards on both of them. You can order the correct label from Elecraft. Obviously the transverter will not work if the IF cables are reversed. This had me going in circles on one I built recently. When using the transverter with a single TX/RX cable J2 and J3 are connected together so it does not matter which one you use. But when using separate TX and RX cables the paths are split and J2 must be used for the RX and J3 for the TX.
The BNC tees will need to mount at a 45 degree angle and you will need to make up several short 3-6 inch coax jumpers to use to connect the transverter stack. You will also need to make a pair of BNC to RCA cables 2-3 feet to connect the transverter stack to the K2/XV60M Don Brown KD5NDB ----- Original Message ----- From: Paul<mailto:[EMAIL PROTECTED]> To: Elecraft@mailman.qth.net<mailto:Elecraft@mailman.qth.net> Sent: Tuesday, July 06, 2004 9:19 PM Subject: [Elecraft] Transverters Reflector Members and specifically: Simon Lewis Don Brown Eric Swartz Thank you for the help on the transverters. This evening I removed the AB switch and made up connectors with RCA's coming off of the 60 meter module option and BNC on the other end for the Transverters..... but now I have a problem with incoming audio. Yesterday, using the AB switch, the incoming signal volume worked fine and now there is hardly and audible signal and no reading or just barely an S1 bar on incoming signals. So maybe I jumpered something wrong or I used the wrong connection diagram or maybe I did not properly tune the 60 meter upgrade module when I put it in..... Can any of you offer some insight into where I might start my troubleshooting on this.... FYI : I am using the diagram on page 66 of the transverter manual and I used the jumper setting for -20 dBm(.01) to 0 dBm(1 mW) which is listed as the following connections: JP1: 1-2 JP2: 2-3 JP3: 1-2 JP4: 1-2 JP5: 2-3 JP6 2-3 This XV144 is deaf as can be now.. and it was not with the High RF output and an AB switch. So I have missed something somewhere! XV 50 is low audio too. By the way - How do you get those BNC T-connectors to fit back there. I had to use them in the vertical positon and then set the transverters on a book so they did not bend the wires coming out of the bottom of the T-connector when hooked up to the transverters. Are you using a special BNC designed T connector that fits back there?
