Anyone have a working one they want to part with?
I recently purchased a Mastr III repeater and the person i bought it
from said he would include the software. Well, after over a month I
finally got the software and it's for a Mastr IIe (from what I have
read they both use the same or similar software) it reads the machine
OK but I cannot
What is the allowable deviation for a two meter digipeater in amateur
service? Is 15 kHz excessive?
If this is on a standard 1200b User LAN keep the deviation below 3.5 KHz -
anything down to 3.0Khz should keep most user devices happy.
If this a 9.6kb digi keep that deviation under 3.0 KHz -
try launching the program Mastr.exe /M3 and see if that does the trick.

I've had a Zetron 45B kickin' around for a few years, and now I'd
like to use it ...
Problem is, like many others who live too far away from parts
sources, I have a tendancy to borrow parts from one gadget to build
another.
At one time or another, I borrowed U2 and U30 for a controller
I THINK this is a repeater phone patch, don't find it on the sites
Zetron Link, any ideas???

Some of my over the pond friends sent the above out. If
you have a bit of time to read some non related text.

The only way to do the close spaced frequencies 447.750 and 447.850
is with a hybrid type combiner.
One is not restricted to using a hybrid... it's just a question of
how practical and cost effective going another route would be.
Real world loss using a hybrid is over 4dB per leg... of
Real world loss using a hybrid is over 4dB per leg... of which I'm
not a fan about space heating a radio vault with terminated rf power.
The quadrature hybrid itself should only be 3 dB theoretically, typically
around 3.2 dB in the real world. It's the external circulators that need to

Now that's a neat idea... I'll file that in my head and claim
local credit for it when no one here is paying close attention.
Unless someone is really trying or just gets really lucky... it's
my opinion the nulls from a side mounted omni shouldn't be that
deep if it's properly offset
The quadrature hybrid itself should only be 3 dB theoretically,

circulators that need to be added to get the necessary isolation
that bumps it up to around 4 dB.
Yep, the overall package has much resultant baggage.
You can

Good lord, I never even thought of that. Another one for the file
until you have a chance to try it out somewhere file. LOL!
