Main issue with portable use is many laptops cards don't have good stero line
in. My IBM T41 is very poor even on the mini dock. Probably need something like
a USB soundblaster, which was recomended by G8JCF for his software.

you can centre drill the mounting holes and use those. What he had trouble
with was the very fine artwork, and either etched away the tracks or

Subject: [soft_radio] Re: Elector Boards
David,
Thanks for the information. The Elector seems like a poor path
1) Whats the phase jitter on a typical PC sound card?
2) Doesn't the divide by 4 reduce jitter. The chip is not used to
generate the IQ directly .
3) The ready built price to the UK is only marginally more than I can
buy the bits for. I can't find a ready built general coverage
David,
If you are a real purist why not sample at RF? I know the cost is about 4x
the cost of the Elektor kit but the result must be worth it. When I looked
at recent reviews in RadCom the direct sampling boards came out realy well.

On the other hand I have had lots of stuff delivered from the US and Canada
without issue including the US QRP club DDR board, and the SoftRock are
probably still cheaper than WS with the duty. (Mind you they will have to pay
it..)

check use this as the primary monitor.

The 4046 series also is a lot lower frequency than much of the
MC1451XX series. There are a lot of PLL's designed for cell phones and
such available for low prices. The problem is they are all ssop(.025

It may not be pretty, but I guess that it should work.

Using a BCD to binary routine would be more efficient than a big
loop-up table. Any of the AVR or PIC chips can easily handle that.

The kit is not pre-build. However, I do know someone(Chris Waldrup)
that will build it for a reasonable price. It will not tune below 1750
KHz unless you use an external oscillator.
