[MilCom] A couple of freq questions for the MID Atlantic area

[JR]

Sitting here reviewing the days audio on a few freqs and can't really find
anything that helps me ID a couple of freqs so figured I would post
something on them:

238.175 Had as best I can tell all 1st FW fighters up on this freq today and
yesterday. Kept referring to this as COMMON but I am having a hard time
telling if this freq is a Squadron Common or a GK Common. I like to tag
freqs by who the freq belongs to as opposed to who uses them. Does this Freq
belong to GIANTKILLER or the 1st Fighter Wing?

143.75 Today I had a SINNER flight of 4 using this freq as an Interplane
apparently while enroot to GK then pushed 139.7 (I had them there as well).
Can anyone else confirm this freq as an Interplane for the 1st FW? I know is
also used by PA ANG quite often but I had SINNER today and have had other
days where the 1st FW could be found on the freq.

And just for informational purposes I had HAWK up with INVADER JACK 341 on
281.2 for a while today. They switched to what they called SECONDARY 384.1.
Unfortunately I was not recording this freq as I already have it tagged for
use as CRAB OPS at MARTIN STATE. So this confirms this is another dual use
freq for the area to contend with. Kind of surprised they don't cause a
bunch of aggravation for the C-130s out of Martin State.
