[hpsdr] Horton with Trumpet??

[Alex]

The suggestion box is always open! 

Does CAT or C-IV support bi-directional control? To be honest I've never never tried it. I think the remote control capability is that in fact, remote computer control of the radio. What you're probably looking for is a physical feel to the radio (knobs, switches, lights, meters) that is the goal of the SASQUATCH board.

CASMIR as an RF Signal Generator is very do-able, especially if the filtering is moved off to a separate board.

Like Lyle said, would anyone like to step up and take the HF filter and 10w amplifier board?

   Would I be talking out of turn here to make a request? Profuse apologies if so and I'll go back to just observing, but this topic touches on something I'd like to experiment with when I finally get my hands on an HPSDR.

 I'd like to be able to use Cashmir as a "modulator" to plug a signal directly into a receiver. Obviously an external attenuator would do the job, but if there is a way to get the low level signal directly from Cashmir that would be nice. Where I see this being useful is in the remote receiver scenario where the operator would prefer to use his old rig as the interface rather than a computer. If the rig has serial control such as CAT, then these control signals could be transmitted to the remote PC to move a filter (virtual/proxy receiver) over the Mercury output or whatever. I haven't though too much about the TX side but it's not hard to dream up scenarios.

 Another use for such a feature in Cashmir is where HPSDR is used as a flexible RF signal generator, in which case perhaps an option for a switchable output attenuator might be beneficial if there's room.

 I'm back in my box now (c:

 If Casmir has to be split to a seperate HF only version does it not make more sense to give Horton a trumpet and so amalgamate the designs??
  
 Following from Alex's comments I can imagine a QSE/QSD to set of 10 x4 pole active filters, amp reverse switchable by say FST3125/6 using Norton style amp with either 4x PMBFJ310 or BFQ17etc. Tx output could be brought up to say a 10w level with the new Mitubishi RD00HHS1 driving a P/P pair of RD06HHF1 MOS Fets.
