If I can help let me know.

I had to find a manual...

Yes, the 2 channel model has 2 of the MURS frequencies
The 8 channel model has the 5 MURS freqs plus other
licensed frequencies on it.
The other frequencies are licensed so you'd have to be careful
about those in non-emergency situations.
(Businesses lease those frequencies and tend to get upset
when someone is using them without authorization)

Another radio you should consider is the Radio Shack 19-1210.
There's one on ebay right now, they're a 5 channel mobile radio and
all 5 of them are the MURS freqs.
They're discontinued but I've seen them for sale often on ebay
for under 100 dollars.

No matter which radio and frequency you use, be sure to
listen for a couple days to be sure that the frequency is not
in use by local gov't or business.
Some of the MURS freqs are still in use by their original users
and they were grandfathered-in when MURS was adopted.
These users have the "right of way" on their frequencies.
i.e. A local Fire Dept is still using on of the MURS freqs in my area.
You definitely do not want to "talk over" or interfere with a fire department dispatch!

What is the scrambler function actually do on these kenwood radios? The manual says the conversation will be private? Its just a function that you can enable. I would think if it were secure it would require a shared key between the radios?

Is it reasonable to expect a standard antenna connector between these radios?

[Justus]

Here's the link to the manual.
Page 39 gives the scramble function details.

Yes, it is a standard connector type but not necessarily easy to find.
Looks like it may be SMA.
You would probably need to have a flexible RF adaptor made that will adapt the
antenna port on the radio to a more common type to allow the
use of an external roof top antenna.
This is nothing more than a short piece of very flexible coax between your radio
and the antenna's coax.
It will keep the antenna jack on the radio from becoming loosened by the strain.

Justus, Do CB's require a license anymore? I was thinking that they deregulated them some time back. I was into them about 30 years ago. I have my short range (2 mile) comm taken care of with the new "30" <Cough> mile Midlands. But might be looking at SSB CB's to get some greater distance out to 8 miles in clutter. I figured they might be the "Easy" way out.

[Justus]

Nope, a license is not needed anymore.

We've had good luck with MURS in hilly, wooded areas so it should be a snap for you. Word of advice, don't get the cheap plastic clamshell packed radios. Get on eBay and buy a good set of Motorola radios. There IS a difference!

I actually got a used set of kenwoods. I should have them later this week. The land here is mostly flat but there is houses and trees everywhere. Expect my full report once I have the bugs worked out of them.

I checked at cabellas and couldn't find a single set of murs radios. They must have 40 different radio set but they all seem to be frs and gmrs. Its no wonder murs never took off. All the better for me.

I got my radios now so I'm looking for some advice on antennas. I'm using the 2 154. frequencies listed in the murs band. 154.570 MHz and 154.600 MHz. I don't know enough about antennas, would a vhf marine band antenna work for murs? The lower end of the marine band frequency is 156.xx, or should I attempt to build a copper pipe jpole? I ordered a better set of rubber duckies but they're 3 weeks out.

Thanks
