Thanks everyone lets let the thread die. Regards Paul.

The next issue might be that they only have them in die form. The issue after that probably is that you really want the version 3 (or 9) chips that actually work with all the modulation schemes. I’ve been down the road with a number of similar chips that took *many* rev’s before they really did what they were intended to do.

Kind of a crazy thing to do but hated to see the systems die. Regards Paul WB8TSL On Sat, Jul 11, 2015 at 11:14 AM, James Robbins wrote: > Does anyone know of any other genuinely useful purpose to which the > Austron 2100F, SRS FS700, etc receivers can be put in the US since the > demise of Loran?

They're in the same TO5, but I don't know if they're the same die. I have about 45-50 microvolt difference between their bases. >Anyway, the take-away is that you should look at that discrete >op-amp and see if it is not causing you the thermal dependence you are >trying to locate.

Frankly spinning down a real hard drive is a bad idea... spinup/spindown is where drives die. it's when you let the system sleep/hibernate is where really things go wonky. If the processor goes beddy-bye, communications go away, and with SCPI devices the world stops spinning. ----------------- > I did have the HD set to spin down and monitor to sleep.

It's even reworkable (e.g. you can soften the blob & solder and scrape the die off and bond a new one down). I suspect that there is a wide variation in the material you blob on there and so forth.
