Skipp and group,
Years ago back in the 60's when we planned our Amateur 420-450 band we
probably were considered a "rural" area. Now we have every commercial two
way frequency, FM and TV Broadcast and even the 2 Mtr and 440 Amateur bands
are full with transmitters and they are at multiple

Hi,
Consider a crossbanded MASTR II mobile for your remote sites, and use
the receiver for the main site.
Start with a VHF and a UHF MASTR II. Put the UHF transmitter into the
VHF radio and duplex that radio. This will be your remote receiver and
link transmitter. Take the remaining U

I'm of the mind that by time you buy xtals and/or channel elements,
etc. you will often pay more for an old Moxy or equivalent than for a
more contemporary programmable radio. For example, in our satellite
receiver system we're using some flea market GE/Ericsson MDX radios
for both tr

I'm sure this isn't the proper way because you're supposed to peak

The most common and easiest to use is to
find some Maxtracs or M100 or the like with the 16pin plug on the back.
There are a number of systems in this area using Doug Hall voters driven by
these links. A VHF for the 2 meter receiver and into a UHF unit for the
440 link.
No modification
Hi All,
Rather than reinvent the wheel, a couple of our club members want to experiment with a remote receive site. To start they are going to play with a dual band radio, receiving on VHF and relaying on UHF. The ultimate plan will be to have a voter (LDG RVS-8 most likely)

Joe,
I have no idea. I think I may have worked on / seen only one or so of these.
We (the fam.) are doing just fine. A bit sleep deprived, but doing fine all

Mike,
Check the band plans at http://www.sera.org/freq0101.html.
The 440 band plan is at http://www.sera.org/440.html.
I have pasted the relevant parts below. However, I do not know if they
will appear formatted properly

Hello to the group.
Has anyone found a good source for some inline attenuators like 3 to 9

was wondering if there was a place that had some surplus or at least a
place that wasn't charging an arm and a leg. I would like to tame

( 16.7 Mhz.) so the TX will above of the

Sometimes component tolerances may all go the wrong way, and will limit a
unit's ability to tune up outside the specified band. If you look closely,
I think you will find that the MASTR Exec II and the MASTR II multiplier
exciters and receivers are very similar in their basic design.

You will need to replace some parts to get it to work. I have one working on
53.01 tx but it was a pain, required some cap changes and still didn't want to
tune up too well. If you can get your hands on a low band mastr II they seem
to go up there w
I am currently running an Exec II for a 6 meter repeater but do not
have the manual. I was able to align the entire RX fine without the
manual but am having trouble with the transmitter. I have gone
trough and peaked everything for max output but I know it's not the
proper method.

Thanks for the reply. I don't share your 'asking too much' stand. As it
sits, the unit covers 77 MHz (450-527 MHz). I only want it to cover
about 36 MHz (440-476). On top of that, I don't think the performance at
449.900 MHz and 449.925 MHz is going to be that much different than
450.000 MHz (100 &
Yup, that's it, convenience or performance. Seldom do you get both in the
same radio8-)

I think you are asking too much of the HT750. I ordered Range 1 UHF
HT750 radios for my employer, planning for interoperability with a
nearby Government agency, and it is remarkable that the radios meet all
specs over the 403-470 MHz range. I have tried to program them above
470 MHz, with no luck
