[MRCA] weekend

[Meir WF2U]

I haven't been on the net for a long time!

Since I reorganized my shack and grouped my gear in different sections
according to branches of service and even countries, I didn't have time to
hook up anything (I need to build a bunch of cables as well). My only
boatanchor station capable of AM which is hooked up and operational is a
"civvy" station: a Collins 32V2 transmitter with a National NC-300. 

Talking about the ARC-38: I managed to find one original, "non-A" as they
say in the R-390A circles... I have the original military power supply for
it and also a 115 VAC 50 Hz to 115 VAC 400 Hz static inverter. I could only
find an ARC-38A control box, which is actually a depot-converted one
originally made for the ARC-38. The mods are listed in the ARC-38/ARC-38A
manual so I may be able to reconvert to the original if I can figure out how
to disassemble the control box innards, which looks like a Chinese puzzle
and packed like a sardine can. Anyone with experience/ideas of converting
the function switch back to original or just using as it is, simply using
different pins on the remote connector? 
Or, better yet, does anyone have a line on an original C-1398/ARC-38 control
box?


Hope to rejoin the OMRN net soon!

I managed to get myself out of bed at 5:30, went to the shack to turn
everything on to make a late check in, only be greeted by a solid wall
of QRN. Only caught a couple of words here and there. A front was moving
through the area at that time. At least the grass got a good watering.

I agree with that assesment. My R-648 is working, but it does need a
mechanical overhaul, the tuning is a bit stiff, plus the BFO  wanders
around a couple of kc. I think it is the varactor tuning, either a bad
pot or maybe the varactor itself is going south.

Would have been neat to have another ARC-38 to ARC-38 qso. If Pete
JWU gets on, we could have a three way.
