[hpsdr] Fwd: Horton Local Oscillator

[Alex]

Well here's my 2 cents on what I though each card was going to be doing:

MERCURY is going to be the 0-30MHZ general coverage panoramic receiver?

HORTON is going to be the 192kHz receiver with two version (HF bands and VHF+ bands)?

CASMIR is going to be a transmitter with two versions (HF bands and VHF+ bands)!


I think we're missing MERCURY functionality for everything above 30MHz

The current discussion on HORTON is missing the VHF and up aspects of the LO.

CASMIR is going to use the common LO design being discussed.


Quick, somebody distract Bob, Lyle, Phil & Phil so the rest of us can finish catching up!  : )

And the paper referenced above says in part:

> Horton requires  I and Q square wave signals  to drive its QSD. 

The signals are required to cover the HF Amateur bands in discrete steps.

For discussion purposes it is assumed that the steps will be 10kHz and

that interpolation within these steps will be done in PowerSDR.

Maybe this is a naive question, but are we limiting "Horton" to
receiving only HF ham bands?

I cannot find any reference on website or wiki that really specifies
this, although the HPSDR introduction (on both) refers that the HPSDR
project is of interest to both licensed ham radio operators and SWLs.

If Horton is intended for ham band only reception, then we need to say
so.  If it is intended to receive 0 through 30 MHz for instance, then we
need to say so and plan the local oscillator accordingly.  If ham band
only, is anyone thinking about another module for 0-30 MHz???
