[HoustonHam] [Microwave] Parting out 6 GHz gear

[Chris Boone]

AHH that's the old ATT microwave (Cold War) path from Houston to the Western
Union bldg in Beaumont AND the KPAC 4 studios in Port Arthur (there was a
baseband Y at Felicia near Devers with a funky looking tower there that had
three supports and a dish IN the middle looking east and the other at the
top looking SE and two different paths). I have the maps from ATT
LongLines...but KBMT didn't own them...ATT did! It also carried the LD phone
calls between BMT and Port Arthur to/from Houston and later into La..when
the Peveto site near Orange was built linking Bmt to Vinton La which was
already talking to LCH and beyond.  AHHH TWTs.....I thought Klystrons and
Maggies (Magnetrons) were the tube of choice back then....

STLs are in the 7GHz range for TV...1.8 to 2GHz is ENG or RPU for TV.....

Will get with ya in direct email about the 6m stuff.....I may have a use for
that......Micors on lowband I pass on......the NB doesn't work at times due
to it going into oscillation and jamming the main channel (had that problem
at GSU/Entergy with our LB bases...ALL the MICORS did it...none of the GE
MSTR IIs did)....which is why GE is my choice for rptr gear...my 444.5 BPT
machine is a 75w MII that is 35+ yrs old, has a ARR GasFet on it and 50+
mobile mile radius from the center of the Triangle.....outdoes every 2m rptr
in town...and then some (well it being at 600ft doesn't hurt)...HT coverage
is 30+ mile radius from the site...No MICOR could do that 

(but I DO have a MICOR going on 146.94 in Beaumont; 9db at 500ft directional
NE nulling Houston with 103.5 PL..under the call W5APX, Art Kay, SK who
owned the local MSS..I now hold his call as a club call and its on my 10m
remote base off the UHF rptr..and I am adding the 224.5 rptr soon to the mix
after the tower work is done AND my 444.8 Conroe is returning to the air
next weekend....followed by 224.8...the 6GHz m/w path is gone now; broken in
Livingston and on the south path in numerous places...replaced by OC48 Sonet
fiber)

Slowly building my M/W side...have the IFR1500 and getting more gear every
month for my IT/Telecom/broadcast engineering company...almost bought a 0.3
GHz (300MHz) to 22GHz analyzer.....for less than $5000....a steal...(may do
so yet)
