It has IF offsets, multi VFO, and many other nice features, best one I've found so far. The IF offsets are set up for high side injection, it wont do reverse tuning needed with low side injection. I use a 100mhz SMT oscillator and disable the X6 multiplier in the set-up menu. It works well up to about 35 mhz. Good luck, VE3ELQ Nigel Hi Has anyone had any experience of building / using a DDS VFO ? (I saw the previous post from SP7EWL). I reserached the possibility of using a DDS VFO in a home brew TX/RX I want to build, and would appreciate any comments. I am particularly interested in the DDS VFO by SS Engineering, (N3SAD). Comments ? Adrian Rees M1LCR |
