I am getting ready to install new antenna on tower with a run of LMR 900 on
tower and a run of 1/2 heliax on tower.
my question is whether to go with the lmr 900 or the heliax.
I have read lots of discussion on duplex noise and duplex noise using LMR 400
does the same hold true with 900?
LMR900 has the same problem. The issue is any foil/braid construction.
Heliax is what you want.

I have a number of M57729L which are 400-420. The H is 450-470. These
hybrid parts lose gain pretty rapidly outside the spec'd range but will
make power over quite a wide range. The L will make spec up to 430 or so
an have full power capability at reduced gain to almost 440. Probably
not an
I am looking for a squelch gate card for the MSR2000.

Does anyone have a readable set of instructions to move a Sinclair R102G
duplexer from 39 Mhz to 6M? I would like to get my repeater on the air ASAP and
tuning the duplexers is all I lack.

I have a question, maybe two on the Motorola HT-1000 portable radio. On the
Repeater-Builder's information webpage that talks about how to decipher the
model number example: H01SDC9AA3BN
The forth digit/letter defines the working spectrum example S for the range
470-520mhz, R 438-482mhz, etc.

Douglas,
Your range information is a bit off target. The 'R' range typically operate
in the 403-470Mhz range while the 'S' range radios typically operate in the
450-520Mhz range. These radios do not take well to any sort of retuning as
you put it but the 'S' range radios can usually be easily
Douglas,
According to the HT1000 Service Manual, the model number H01SDC9AA3BN breaks
down as follows:
H - Handheld Portable
01 - HT1000 Model
S - 470-520 MHz
D - 4.0 - 5.0 Watts RF Power
C - Standard Controls, No Display
9 - Channel Spacing is Variable/Programmable
A - Primary Operation is
Eric,
Manual 6881200C75 was updated in manual revision FMR-1686-1 to show the
splits we've all come to know as 403-470 and 450-520 beginning with radio
version B. The 'S' split radios usually take nicely to the 70cm band in my
experience using the SHIFT key method in fact, I have two here working

And I follow the information 100%.
Needless to say, your radio is not a good candidate for use at 70 cm. While it

Looking for a way to make Puxing PX777 as a Manpack-repeater
Puxing PX777(+) has VOX, with VOX you may use two rados as repeater by connect
mic to spk / spk to mic, placing radios away from eatch other in that way it
will not interfer with each other!
may use duplexer as well here!

Hi all;
I am currently deployed to Afghanistan. I received four quantar repeater/base
stations for use here, plus 140+ XTS5000R handhelds. I am attempting to setup
the Quantars as repeaters on the VHHF1 band, in non astro/analog mode. I have
one setup with a separate transmit, and receive
15 matches
