I picked up a Micom 100 a while back, and was thinking of putting crystals for 60M in it. However, I was wondering how difficult it would be to use a N3ZI DDS VFO, instead. This would theoretically allow me to use it on 75M, 60M, and 40M. If the filtering has enough "leeway" below 2.0 Mc, I might even get it to work on 160M if I'm lucky.
I understand from reading a previous post that a buffer amplifier will be be necessary to use between the VFO and crystal oscillator in the Micom.
I've got a few questions about doing this:
1. What would I hook the output of the buffer amplifier to? I've used VFOs before, but they were generally hooked up to the crystal holder inside 23-channel CBs I converted for 10 meter use with Siltronix VFOs. Another post leads me to believe that this may not be the way to hook up a VFO to a Micom as the poster said that it would be hooked up to the crystal oscillator, and the channel selector would be used to simply select what filters to use. I'm a bit confused by that...
2. Does anyone know where I can get LSB crystals. My unit only has the USB and AME ones.
3. Has anyone ever done this or a similar procedure on an older crystal unit. If so, I'd really appreciate it if you would share your experiences.
Thanks and 73,
