Thanks Tim, VFO A is unlocked if I use the XVTX\COM port for Tx. VFO B is restricted to the ham bands on the same port. 2200M is now available to all VK advanced calls at 1W ERP. The transverter form doesn't seem to work without an Rx converter. I made one called "137" with 4MHz LO. Band 135-138KHz. Rx is on 4.137 but no Tx output. I could use a low side IF but that reverses side bands etc and makes me dizzy. Or I could change to a 10MHz LO but frequency accuracy is harder. (Unless I use my 10MHz TCXO from another project). Its bad luck that the F1500 has no usefull output on XVTX\COM at 137KHz. It cuts out below about 495KHz. Andrew
