Ross, Expanding a little on Chris's reply....
The PowerSDR software will allow you to operate the relays on the UCB board via the X2 connector on the SDR-1K. And as Chris pointed out, the XVTR button on the main menu bar will lead you to the main transverter screen where you can specify which button you want to use for which band, what you want the button to say, what the frequency offset is for each transverter, and what the frequency tuning range is for each transverter. You will want to define separate buttons for each band. Now, in addition to all that, you will need a coaxial relay that will switch the RF from the SDR to the appropriate transverter. See Mike King's excellent article on his web site at http://km0t.com/ . With only two bands to contend with, you could use a simple single pole, two position coax relay similar to what is normally used as a T/R relay. In one position, the RF output of the SDR would be connected to your 2M xverter, and in the other position, the RF output of the SDR would be connected to your 70cM xverter. Use one set of contacts on one of the relays on the UCB to control the switching of the coax relay. You will also need to get the PTT line to both xverters. In some cases, you may find it useful to key both xverters at the same time so the RF output from one doesn't damage the RX front end of the other one. The PowerSDR software is incredibly slick for controlling multiple xverters. I am currently controlling 8 separate xverters with mine, and it works like a champ. I'm working on an article that describes the whole thing, and hope to be able to submit it to the knowledge base in the near future. Hope this helps.

The idea seems to be that you use the VHF+ button on the Band Panel, which switches the buttons from HF bands to just numbers. Then you set up what you want the buttons to mean on VHF via the XVTRs Window. In particular, if you enable Band Button 0, for example, then you can select the UCB Address [= Relay Number. Note that the Pins on the ExtCtl Panel represent the _bits_ of the UCB Address with Pins 1-4 giving you Relays 0-15.] You can also set up other useful stuff like the real frequency covered by the XVTR. There is a little more detail in the 1.8.0 SDR-1000 Manual, Chapter 9 Operating Forms. I'm not completely sure how you are trying to set things up, but it sounds like you have only two choices - select 2m or select 70cm. That sounds like a single button/relay will do using the normally open connection. E.g., enable Button 0 for 70cm and select UCB Address 0. Then, when you select Button 0, the UCB relay will close, switching your control relay to the 70cm position. If you select any other button - enable another one for 2m and some other Address - the relay will release and the control relay will switch to 2m. That's probably garbled some but I hope you get the idea. Keep me posted.

Day Subject: Re: [Flexradio] UCB schematic and header question Thanks Chris, that answers the question exactly. My next question is related. I am trying to use the UCB in the following manner. I have my SDR1000 1 watt rig, set up to drive a transverter on 2m an 70cm. by enabling 1 and 2 in the XVTR option. I have relays feeding the 2 and 70 transverters, I wish to use the UCB to control the relay that selects either the 2 or 70cm relays. So far I haven't worked out how to do it. My idea is that when I select say 1 (which is 144mhz) then the controlling relay will switch the SDR output to the 144mhz relay then to the transverter, similarly when 2 (432) is selected the controlling relay will switch the input to the 432 relay. Using the EXT CTRL in the setup doesn't seem to work. Ideas as to what I need to do please. Thanks Ross ZL1WN ----- Original Message ----- From: "Christopher T.

The schematic is not up-to-date. 2) These are for future enhancements. Leave them open. 3) INP6 is a "virtual line" on the schematic. The two instances of it connect together. In other words, the PCB connects the top of R1 to Pin 3 of U8.

My apologies if it coms up twice. I have built up the UCB , but I have a couple of questions. (a) the schematic on the K3TUF website does not show U13, U14, U15 etc is there an updated schematic anywhere? (b) at the bottom of the board is a 10pin header, this does not appear to be in the schematic either, are these pins supposed to be jumpered? if so is it across the board? (c) what is INP6 (as shown on the schematic) and where does it come from? Assistance please. Thanks Ross ZL1WN -------------- next part -------------- -- No virus found in this outgoing message.
