Are FETs supposed to glow like that?

That was R6 from the base of Q2 to ground...

On the earlier versions, it was not installed from 40 meters down. But was for the higher freqs.

I believe on the later versions it is used for all freqs. (but labeled R16)

That's a 22k or so, not critical.

And you need to omit C4 as well.

Ok, just realized the message I passed on from Tony, referenced the Softrock Lite II schematics...
NOT the v6.2 schematics...

So, here's the corrected parts labels: for v6.2 Softrock Lite

R6  22.1k
C3 100pF
C4 not used
L1 34T of #30 on a T25-2 core (4.0 uH)
T1 9T of #30 on primary and 5T of #30 in each of the two secondary
windings "bifilar" over the top of the primary on a T25-2 core (0.25 uH on primary)
C21 = 100 pF
C22 = 1500 pF

If you put it on the 8.2 IF Tom, be sure you put it before the filter, otherwise you'll be limited to 15 kHz total bandwidth. If that's enough for you, then connecting the SR after the filter will be FB.

I would interface it after the filter since he doesn't have a stereo input. This will eliminate a lot of bb crud. You will need a better sound card to see the real performance.

It looks like SOFT ROCK is a bust ...All the kits are" check back later" 

That is just the strange way he does business.  For some reason, he does not want to take orders  unless the stuff is ready to ship.

How he determines what and how much to build next is a mystery and of course the reason he has these "check back" delivery schedules.

It's a pain in the butt for the customer but it's his business. 

Sooner or later, he will take orders and hopefully have built enough to work yours in.

I contacted Tony Parks via email and he promptly replied.  Today I got an email stating that many of the kits would be orderable at 8:00 PM EST today.

Sure enough, I went to his website and they were there.  I ordered the SoftRock v9.0 Lite+USB Xtall Receiver with Si570 and Electronically Switched BPF Kit. 

If you want a softrock, place your order before they are gone!

Tom, did you ever get this working? I have an FT-1000D with an I.F. board problem where the logic doesn't bias the diodes to select receive filters. I'd like to marry it to a softrock and call it a day.
TIA,
Dave W2VW.

Tony will have kits available on or about the 10th of this month for what is listed on his web page.
A different fellow is handeling the IF kits. See http://amfone.net/Amforum/index.php?topic=24547.0

Dave,

No, I never did. The changes were just too much considering it is surface mount. Plus, I realized, that I want to monitor the FT-1000D itself, so how cud I use the 1000D as the front end?  :-)

So I'm going to use a 455 kc version off the SP-600 IF and work with that as a spec analyzer for now.

Use an "AM Courtesy Filter" to limit transmit audio bandwidth  +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed.  Easily done in DSP.

Tom if you send me a schematic of the FT1000D IF I can help you interface the softrock. I know of a number of people doing it at 8.2 MHz. After the filter would limit you to one bandwidth. Since you now have stereo input it should be ok to interface ahead of the  filter.

Thanks for the offer, Frank.   As I mentioned above, I want to monitor the TX signal of the FT-1000D driving Dr. Love.  The 1000D RX is disabled during TX. So I will be doing the conversion with the SP-600 at 455 kc.

Same way the FT-1000 does it itself (monitor function) - use the second receiver.
