hi all, seems i'm trying to get a db 4062 duplexer to work also i have
the tuning info however its the 'c' model and i would like to make it
a 'b' model, which meens i suppose the cable harness lengths are longer
and one set of loops is longer...i've tried to get the info from DB
SPECTRA but
HI Mike, the connectors were actually new, only been up about 6 months when we changed the antenna, but we did check the hardline before connecting the antenna and nothing showed up. I even added a short length of coax onto the end just to make sure it was not a length issue and no changes.
Hi
I have copied a GLB 300A Channelizer (synthesizer) kit manual to a PDF
file.
The manual is for the building the kit but also contains trouble
shooting information.
If any one is interested in a copy, please email me direct.
Be aware that it is a large file (10 Mb).

Hello All,
I am finally getting the time to put my UHF repeater together and I
am in need of two items to complete the setup (for now atleast) I have
the rx, tx, amp, powersupply (EF Johnson CR-1010) Duplexers (DB 4072,
huge thanks to John of Maire-Radios for his help with getting them)

Hi
I have asked this before, does anyone in the group
know
of anyone who makes 6mtr heliax duplexers and can
send
to the UK.I have been let down a few times here in
the UK.

I'm going to do the process of elimation again tomorrow. I did remove the amp, however I did not bypass the duplexer's, and with just the exciter at 5 watts, I don't get anything, and out the duplexer is right about 3 watts, so hard to see anything. As for hearing on 133.300 it can be heard
Hi Byron,
I don't see your full email address when reading the group
posts on the web, so I have to respond back through the
group. Please email me a copy of the manual. I have three
or four of the channelizers... One or two were purchased
at a flea mkt last month with the micor channel
I have been reading these post for a
couple of days now and seen in the original post that you are loosing 110 watts
in the duplexer. Maybe Im the only one that thanks this may have
something to do with the problem.
What is the SWR between the tx
side of the duplexer and the
Did you get an answer to this? I've forgotten what the A, B
and C ranges were. I have a DB4062 which is 143 - 156 MHz.
I can measure the cable length next time I am at the site
(should be within a few days). I'm not sure the loops
would be any different between the ranges, but they
I had a document on cutting a PD-128 ground plane to 6 meters, but can't find
it now. Anyone have the information?
Thanks ahead of time,

How many of each do you need and what size are they? What attenuator are
