How about duty cycle? Do you think this set up would transmit 7x24?

Thanks Buch, I'd like to build the link so that it transmits all the time. That
minimizes key up delays and reduces intermod on the hill. So need something
that can key down forever.

Hello Tim.
The entire radio, with the transmitter, receiver, card cage, power supply
and cabinet is $400.00
If you need just the receiver, transmitter and card cage is $200.00.
Some people do not want to pay the shipping for the power supply or cabinet,
that is why I break it up into a smaller
It was asked if they were similar. I replied that they are not. I
figured there were too many things that were different to elaborate further.
They are both made by Motorola in Malaysia. They are both programmed
using a PC computer (albeit by different SW packages). They share the

Wofle appears to not be in business as I can't find them on the web.
Any other ideas where I might find some UHF low split Micor parts?
If it's got to be Micor it's hamfest
Hello Tim.
I just looked in my storage site and I found a Micor Base/Repeater which is
on the band split of 402-430 MHz. I do not have channel elements for it.
I know it was working when it came out of service a few years ago, and the
PA can be used as a digital station, as it takes the four pin
I disagree on the price of the CDM's. You can get the CDM-750 (4-channel)
for as low as $75 to $125 if you watch for them on e-bay. The CDM-1250 and
CDM-1550 are more expensive used, but still you should be able to get them
for $250 or less if you just have to have the 128 channels and alpha
What's it take to program those radios?

Look at W6KGBs article on moving 450-470 Mastr IIs
to 420-450. It's on the GE Mastr II page at repeater-builder.
You could use a Mastr II UHF mobile with the receiver,
exciter and IPA converted to 420, then use the receiver
in an aux receiver chassis at the voter site.
You wouldn't need to
I am using the Motorola CDM series of radios for 420-425 MHz links from
voting sites. They make a low-split UHF split that covers 403-470 MHz out
of the box, no mods needed. On the transmit sites, you will want to use a
fan for cooling. We mount the RX radio and a UHF TX radio on a 1U rack
When you say low split, are you talking about the Motorola
TRE1201/TRE8031 406-420 Mhz receivers?
I don't have a manual in front of me, but yes, 406-420 receivers, they'll
work fine well into the mid 430's without mods.
What Canadian sources might have these?
Well, Spantek comes to mind
