| O tym chyba mowa? Auto LSB Mode for the UK/RT320 radio This is the circuit I used for the LSB mod ,it was found on Iain Moffat`s web site http://www.g0ozs.org/clansman/lsb/index.html Al li did was to add an inverter to the enable line . The board was made from a bit of copper clad that I had at the time The 12v was taken off the Ref osc module (red wire) and the enable was taken of the 10`s of Mhz switch (brown wire ) . I cut the track near to TP F see picture f.jpg . for the switching of the original and new oscillator . and that's about it . Below 10Mhz it is LSB and above 10Mhz it is USB . After I did this one I looked into a rewire job on the mode switch ….. At first I thought no way but after a second look it is not that bad, two links to remove one resister to fit and one wire link to add and one wire (only one) on the switch to cut. See second part to this . Ian G0TJH |
