    Ah ha! I was just about to post to the hf projects group that very question. I think I will give the Packer Amp a try !! Looks like a really nice kit. Thanks

        I modified my softrock so that it has a broadband balun for both tx and rx, and I'm working on an external amp (using the kit from Kits and Parts http://www.kitsandparts.com/linearamp.php) that takes the output from the mixers, puts the signal through a bandpass filter (built into the amp box), and then outputs the signal (through more filtering).

        I also incorporated a receive preamp in the circuit that should eliminate a lot of the rx problems I've heard about (but only experience to a small amount). The goal? Have a QRP rig that out performs and is cleaner than anything available through the "market"- and I think that might end up being the case!

        The whole idea was to build a modular system. Seperate softrock that can be used (plugged in) to many different setups and circuits. External filtering as needed. External amp as well. I can also by switching cables use my softrock as an IF receiver, or as the basis of a nice transverter-style 2m SSB system... or for any number of applications.

        BTW- The softrock was built into a nice rf-tight case with feedthroughs and very strong isolation of any noise source, as well as proper audio-type grounding (single point). That makes it an awesome receiver even without the impedance-matching preamp, and I'm looking forward to seeing how it works on transmit!

        (I just wish that they'd port Rocky to Linux, and add SSB capacity to the software!)

          Good practice for any radio gear and with digital circuits in close
          proximity I tend to use lots of ferrite on external leads also. On the
          SRv6.3 + E-MU 0404 USB with 2m of very heavy figure-of-8 audio cables, I
          have 3 rather large ferrite rings.

          You stand as much chance of having Rocky ported as you have of being
          struck by lightning down a coal mine. Flex promised way back to port
          PowerSDR to Linux, but since have been silent whenever the topic is raised.

            Hi - I also use currently the 6.3 on the air. I have added the 10 W amp from DL2FI http://www.qrpproject.de/UK/qrppa2008.html which takes a 10mW signal at input (+ the output filters from Virgil) - i have put an attenuator after the 1W 6.3 PA, but a broadband 10 mW output could be more attractive. Can you publish your modification ?

              Well, as I remember (I'd have to take the softrock apart and check things), I used the T37-6 (10 meter) core, and wound it bifilar. That was in place of the bandpass filter. I don't remember exactly what I came up in place of the transmit section, but I did match things up.

              You see, last month my shop burned- and I lost all of my notes and test equipment I'd collected over the last 25 years, and parts (no insurance, total loss, and all of my friends consider the fire suspicious- I'm not popular in this area). I'd had all of the notes regarding the softrock out there where I'd built it, including research and calculations.

I have added the 10 W amp from DL2FI http://www.qrpproject.de/UK/qrppa2008.html which takes a 10mW signal at input (+ the output filters from Virgil) - i have put an attenuator after the 1W 6.3 PA, but a broadband 10 mW output could be more attractive. Can you publish your modification ?

Have a QRP rig that out performs and is cleaner than anything available through the "market"- and I think that might end up being the case!

External amp as well. I can also by switching cables use my softrock as an IF receiver, or as the basis of a nice transverter-style 2m SSB system... or for any number of applications.

That makes it an awesome receiver even without the impedance-matching preamp, and I'm looking forward to seeing how it works on transmit!

                    Actually, it's just the reverse.

                    I lost all of the equipment I'd been collecting over 25 years, including the 16 years I had a robotics repair business (and my best friend also lost a lot of his stuff we'd set up in my shop). We had a complete computer controlled testing and experimenting setup (that we were starting to use for amateur radio experimentation) which took all those years to get together (digitizers, scopes, analyzers, you name it). I'd bought people's junk and fixed it in the evenings- because I didn't have the money to buy working equipment (and couldn't afford the prices). So I lost the money I'd worked hard for and spent on the equipment- and literally thousands of man-hours of hard work. There was a lot of homebrew equipment and esoteric stuff lost too, and my laboratory equipment (and several radios I'd collected over the years- waiting for repair/rebuild/restore). I don't have the income to start buying stuff (a new decent soldering iron to replace the burned one at $40 was a huge expenditure with our present income), and don't have the years of time I lost fixing up the equipment. So, It's pretty much irreplaceable- at least for now. It also wiped out our ability to do some experimenting we've been planning for a while (a really different new antenna that preliminary exploration suggests will work quite well, and some other circuits/mods) - until we can rebuild and replace some of what was lost (we're planning and seeing what we can scrape together, including salvaging what we can from the shop).


                    The notes and calculations? All I have to do is look at the schematic, pop the lid and see what I did, and I can re-create most of that including why I did things the way I did. Actually, it all was quite simple. My biggest worry was that with such a simple setup, it would work as well as it does. Essentially all I did was replace both daughter-boards with a couple of small broadband baluns. One, on the rx bandpass filter board, used one of the original boards and the components were mounted on the bottom rather than the top (so it would fit properly in the case). Nothing to it.

                          Thanks for the offer!!! You're the first amateur (beyond my best friend) to offer help!!! (Only one other non-ham person offered to help- and she gave me a box full of junk cell phones. I WAS able to trade them for one working phone...)


                          I'll relate more later... right now, I'm at a severe space disadvantage (we live in a mobile home, and my wife kindly let me use her sewing-machine table for working on stuff), and the money situation is also unbelievably tight too (I'm a graduate student who graduates Sunday, and will loose my part-time Assistantship that week!) So whatever I get has got to be small in size and CHEAP. Indeed, I won't be able to buy anything more for a while.

                          Since I'm no longer in business, I will be focusing more on equipment that advances Amateur Radio and can be used for experimentation. I'd like input on cheap but very effective test equipment kits and so on. Maybe if people had used equipment taking up space... that they wanted to get rid of...

                          I can provide proof of the loss to the owner/moderator of this sig, including pictures of the burned-out hulk.
