Kevin, I am doing something like this. I use a KX3 with an external transverter for 144 MHz. I have a 3dB splitter on the IF out of the transverter (14MHz) and send half the signal to the KX3 and half to an SDRPlay RSP running HDSDR. It can display in to 8MHz bandwidth, though I only need a view of about 500 kHz normally to monitor the weak signal portion of the band. The HDSDR software can be configured to control the KX3 via CAT by point and click and the KX3 can control the tuning of the HDSDR whichever you require. SDRPlay works pretty well for this.
I have used the SDRPlay directly on 144 MHz rather than on the IF from the transverter, but it does require a band pass filter ahead of it if you have strong out of band signals, it doesn't have great RF preselection unlike the Funcube Pro+ which has a SAW filter on 2m. 73 from David GM4JJJ > On 7 Feb 2016, at 22:44, Kevin Stover <[email protected]> wrote: > > Software Radio Labs QS1R will do 2MHz as a standalone SDR covering 10 KHz to > 62.5 MHz. > > >> On 2/7/2016 12:33 PM, Bert Rollen wrote: >> All, >> >> >> I have a young friend who wishes to do the following - >> >> >> (my summary, not his words) >> >> >> - Panadapter (or SDR) with 4Mhz or more display (not just a few >> hundred kHz) >> >> - Capable of 144 MHz - 148 MHz >> >> - Point & click control a rig (K3, KX-3, Flex-6700, rig w/ 144 MHz >> transverter etc.) >> >> >> Essentially, he wants typical pan-adapter display and control, but 4000 kHz >> wide (or more) >> >> >> >> SO, do I recall some folks here who have run a separate SDR to drive >> controls on a K3?
