V1 vs Heat

Check the details. I was able to do some troubleshooting most poeople never have a chance to do.

The zooms don't believe it. That is why I always point a single vent towards my RD.

FWIW, VR fixed it. The repaired V1 performed very well, even when it was hot. (I don't use the V1 often, but the road trip I tested it on was a very long one.) I made a point of not giving it any "help", just to test it out.

Z1NONLY, did you have ver. 3.864 both before and after the fix?

From my post in other thread:

I believe that I probably had a temperature issue back in June with my V1 (ver. 3.826). One day, it completely missed a strong oncoming Ka-band constant-on -- just displayed "A" the whole time and never made a peep. I know the radar was active because I used my STi in spec mode to check (about 34.7 GHz). For those who post in this thread, which versions of V1 hardware/firmware were you running (both before and after any repairs)? Mine is now upgraded to ver. 3.872, but I have not had enough hot weather to really test the new version.

On decoding the version number, I believe that any change in the hundredths digit indicates a hardware change, while any change in just the thousandths digit indicates just a firmware tweek. I would guess that raw susceptibility to heat would be purely a hardware issue, but that particular temperature limits could probably be adjusted in firmware.

Also, if one version of hardware turned out to be populated with sub-par components, it is possible that VR could have identified and replaced individual components when a unit went in for repair, rather than replacing the whole board. Thus, a repaired unit of one hardware type might not have had a version change, while unrepaired examples of that same hardware version might still have the sub-par components and resulting heat susceptibility issues.

Yes.

3.864 in.

3.864 out.

Mine is a 3.826 version with no digital temp compensation. Only 851 and up versions have the digital temp compensation.
