 My pleasant surprise, thanks to all who, in the rush of Christmas eve activities, who took the time to  respond to my WTS email.   I just realized that I missed a couple of things.   I didn't weigh the beast and I didn't get the photos taken.   I will fix that this afternoon and will email the photos in low pixel rate to the responders.

Not always.  If the isolator is driven far below it's rating, it may not go 
nonlinear.  We once tested an EMR Corp. 220 MHz isolator being driven with 
~90 watts.  The output spectrum from our RFPA was no different with the 
isolator in line (no increase or decrease in harmonic content).

If you have a power attenuator handy, it might be worth actually looking at 
the harmonic levels coming out of your isolator with a spectrum 
analyzer.   You can't use a coupler for this test because it's frequency 
response will taint the measurement.

[Repeater-Builder] 6meter cavities

[rogeradio]

I am the RF engineer for a repeater system that includes a 6m repeater that 
has a hybrid-ring duplexer.  Sitting next to the duplexer is a pair of 
DB_PRODUCTS tall cavities that are not connected to anything.  
The model number on the name plate is "DB-4041 H-2".
 
Now I see references to a DB-4042 in the range of 30-60 MHz.   
Anybody know what a DB-4041 cavity is?   Does anyone on the remailer 
have one (or two) of these such that we might negotiate a buy?  I'd like to 
turn these into a BpBr cavity duplexer.

[Repeater-Builder] SWR at Isolator-input

[rogeradio]

I'm trying to install a repeater and have encountered a puzzlement.
 
I re-tuned a Telewave dual-isolator down from 452.xxx to 443.55 
MHz for installation on a new GE M-II 100W UHF repeater.   At the 
site, I connected the xmtr's coax cable to the the isolator's input (yes, it was 
the  Input port).    I connected the isolator's output to 
the duplexer's xmtr-side  port.  I used only RG-214 coax cable.  
I put a 10-watt load resistor. on the LOAD port nearest the transmitter and a 
100W load on the LOAD position next/nearest to the isolator's output.
 
Then I inserted a BIRD wattmeter between the Xmtr output coax and 
the isolator's INPUT port and keyed the transmitter, I read 110W fwd 
and 2W rev.  OK!   But after 45 seconds of continuous 
transmission, the reflected power had risen to 7.5 watts and was 
rising.   I unkeyed the xmtr.  
 
I am puzzled.  I expected the isolator to behave constantly: 
 X watts fwd; and Y watts refl.  This variability I'm seeing makes me 
think that I have a changing impedance inside the isolator .  The 
100 watt load was beginning to warm up in the 45 seconds duration of my 
test.  I swept the duplexer with my IFR to see if the rcv/xmt ports 
were labeled wrong.  Nothing unusual here .   I put the GE's 
transmitter direct to the antenna through the wattmeter and got 110W fwd and 1.5 
watts reflected 
 
What is going on with this isolator?   Should I be concerned? 
 and what do I do about it?. 
 
I would like to have some 
suggestions

[Repeater-Builder] GE tone board ??

[rogeradio]

My question, fellow builders, is - What is it?  What kind of Radio 
might it fit?
 
Like a Phoenix, a strange-looking GE board has arisen from my 
'junk-box'.  It is 3 1/2" square and has six transistors and a slot 
for a Versatone chip, so I think it might be a CTCSS encoder or decoder.  
But, for what radio - I dunno!
 
The board number is 19C327626G1.  It looks like it should have a lid 
over the metal 'box surrounding the GE IC's and versatone chip.  It has a 
6-pin molex connector and a single-socketed wire that looks like it plugs in 
somewhere.
 
Help anyone?

[Repeater-Builder] 320-360 MhZ FM Repeater

[rogeradio]

I just got a hold of two ICOM GR8520 25-watt FM repeater in the 320-340 MHz 
band.  

Has anyone ever heard of any repeater equipment in the gov't air/ground comm 
and Navigation Aid band??  We have glide slope transmitters in that band in the 
330 MHz area.

Has anyone had any experience in this band and/or any suggestions what to do 
with this brand new in-the-box radio?

I think that I'll have to go out and buy a boat now!!  I got the anchor!

Roger Hansen, W6TOZ

Re: [Repeater-Builder] FAA Paint Removal

[rogeradio]

Hmmm!  FAA doesn't paint coax cables!   However, If this hardline was attached 
to  and then removed from a structure located near an airport or airfield, then 
there would be some orange and white paint.  This paint should do no particular 
harm to the coax cable jacket.   

Personally, if this coax you have is RG-331 or RG-333, I'd put it on eBay and 
get some good coax.

Re: [Repeater-Builder] Re: Duplexer cable question

[rogeradio]

I saw some traffic regarding RG-400 and RG-17?.  I have about 100 ft of RG-223 (RG-58 style, only double shielded) on the reel, that was surplused by BOEING that's just sitting on my shelf. If you can use some I'll part with it for $0.25/foot plus mailing.

[Repeater-Builder] GE M2 UHF 40Watt PA section question

[rogeradio]

I am putting together a UHF repeater on 443.775 (+) and acquired a 40 watt (Intermediate) PA deck from an unknown source and started to visually check it out versus the schematic diagram.  
 
Now, the GE manual (LBI30201) identifies my pa deck as 19D321347G5 Rev N.  This matches the yellow label on the IPA deck.  So far so good.  However, the G5 board is listed in the manual as 402-420 and also lists G9 for 420-450 MHz - the same part number except its a group 9 rather than a group 5 and a different part of the band.   Hmmm.  Will I get my 40 watts from this group 5 deck on 443.775??
 
On the same page of the manual, there is a components change table listed by frequency band (LL=406-450, L=450-470, M=470-494, H=494-512).  
 
Whoa there!  the (G)roups are 406-420, and 420-450, but the components don't change between 406 and450??   I scanned the detailed parts list and found nothing that indicates a difference in parts between the 406-420 and 420-450 band.   
 
The only discrepancy that I found is that C257 is not installed on my PA deck and the components table says it should be there.  I checked with my source and all of his 411 MHz PA decks (40 and 100 watt) do not have C257 installed.    I'ts a bear to get at the spot on the PWB for C257.  It's right above the black test socket J5.
 
The big question is"  What am I missing here?  What makes UHF 40-watt G5 PAs different that G9's?

p.s. the reason that I just didn't try it is that I don't want to fry anything just yet.   Smoke must be contained

the CM-51 is a UHF (225-400 MHz)LPA designed to boost AM signals from 10 watts 
to 50 watts @ 100% modulation.

This amplifier is of recent MOTOROLA production and is currently used by the 
FAA and the USAF for air trafic control.

the technical manual is FAA publication TI 6610.18 and has an NSN fof
