Hi, Hank! The transmitter will almost certainly be a fully assembled module,
not a kit, and will be designed to fit in the LD-1's enclosure above the LD-1.
No additional holes will be needed. I was thinking ahead to this when I

As for the range, as you know that depends

Hi, Hank
Hi Pete.
This SDR looks very nice, before I order one do you have some specs on the unit
? I was wondering if you are going to post the schematics online. I could not
find it on your web site. Also what DDS chip are you using Si570 ? or Analog
Devices chip ?

I don't see any reason not to post the schematic, the hardware doesn't really
include anything that hasn't been done before. I do use a proprietary
technique to reduce (and nearly eliminate) spurs due to DDS artifacts, but the
value in the hardware is that I've combined everything in a small,
Hi Kelvin,
Just a trivial point.
The Si570 is not actually a DDS device, uses a completely different method of
generating the final frequency. The net result is that the Si570 has a much
clearer output spectrum, and none of the spurs usually associated with DDS
chips, also the Si570 has

Nice work getting everything working.
