Well I just tryed 2 different machines and cables and for some reason no signals on Pins 1 and 14. I took the cable off from the SA and hooked the logic probe...
Hi Donnie, Yeah, you have a head scratcher, there. I suggest downdloading the program code from the Files section again, just in case it got hosed. Then, run...
This is usually configurable in the BIOS setup. I always set my machines to SPP just for greatest compatibility. Good point... -- john KE5FX ... From: Donald...
Hi All, Just a few updates on my progress with the SSA assembly, each module area: Control Board: No errors and no problems have cropped up in this area. I...

If it is an older Thinkpad laptop like TP 760 or 600 you can download from IBM the "Thinkpad Configuration utility" which will enable you to set all the ports,...
Hi All, After reading Donnie's first post, I went digging on what SPP and EPP was. I haven't figured out yet if I can change any of the "control" signals to...
Hi Again All, Here is what I have been doing on the SSA board lately. I worked on getting the Tracking Generator interference level down to an acceptable...
Sorry, correction: "ps2.exe par mo bi" for normal bidirectional transfers. That is most likely the right mode for the SA. On my 755CE, the "uni" mode doesn't...
Hi All, I just downloaded, in the Files section, the latest software I have been working on for the SSA Board using the LMX2353's for all 3 PLL's. It is...
Because I need to mod the circuit board iam looking at replacing the ADE11x with the ADE25mh which is a Level 13. Would this help or should I go with a Level...
Hi Donnie, I almost don't want to stick my neck out here. I've already shown a poor choice in mixers. There are several factors in determining which mixer to...
Scotty,mixers-is it worth looking at the Linear Tech LT5512 ? http://www.linear.com/prod/datasheet.html?datasheet=906. Available ex Digikey LT5512EUF-ND $7.38...
Peter, Scotty is a key person to comment. This mixer is very interesting but it is only 4mm wide so I believe there may be problems to solder it on the pcb. ...
Unfortunately I suspect that the other interesting "new" one ,the H by Horrabin is probably too limited in bandwidth.See www.qsl.net/pa3ckr/hlmixer. Cheers ...
Hi Peter, I took a quick look at the data sheet for the LT5512. It didn't take me long to turn from optomism to disappointment. There are several things that...
Hi All, I have updated my Web Site for an additional page dedicated to the SSA Board Assembly. The page has all of the schematics for the board, with a...
Hi Donnie, I made the change on the Tracking Generator layout. I tested the change in PLL 2 and the way it is layed out, with the pins reversed, actually has...

I see...well, maybe they should change the description on the home page for the group, which reads: "This is an open forum for electronic hobbyists and amateur...
Jim, you're more than welcome on the list, but do note that the SSA is a pretty different piece of gear than the various CATV tuner-based projects out there....
Hi All, I apologize for not updating sooner. My mother has had a heart attack and is in the ICU. I am at my Dad's house and have the computer to use but no...
Sorry to hear that. :( Hope things go well with your mother. The compromise between noise floor and IMD is an issue even in commercial designs. Tektronix 49x...
