Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

The kit is your 1.5GHz spectrum analyser + tracking
Scene is repairs - luckily not involving YIG
oscillator. Yay, we found the dead capacitor in the
Log-Amp. Now trying to recalibrate..
We are using
one of those AVO-style flexi grab probes, the kind with
two springy wires up a insulated spiral. You push the back
plunger, and the little grabby hooks spring out.
Probe is deep in circuit between mounted boards, hanging
in the hole in a test point tag. At this angle, the darn
thing won't release, so its a bit of a wiggle. Probe
releases, and you see SMOKE!
OK, there is no way
the adrenalin rush and that deep seated sick feeling will
be avoided, but lets not go all out panic. Can't smell it
yet......huh....what is this !??
(Studies end of
probe closely - plunger in - plunger out)
turns out to be little puffs of proby rust dust, wot wafts
upwards between boards when you work the plunger. Dead
ringer for smoke that - real panic - type crap. However
harmless in the end, it took a couple of mins to make all
the emotionals go away.
