You will find my repeater on frequency 147.360 Mhz with a positive offset.
You will need to be transmitting a 77.0 hz tone to access it.

You may periodically hear some DMR digital sounds from this repeater as I am doing
some trial and error experimenting with it periodically.

How does my repeater differ from most other ones? It is a digital audio store-and-forward relay
system. In non-traditional terms, it is often called an "Echo" or "Parrot" repeater. Like most
repeaters, they still allow two operators, who are too far away from each other, to be able to
communicate to one another. It just takes twice as long, due to having to wait for the live
transmission to be recorded then retransmitted for the other operator to hear.

For an example:
Operator #1 calls for operator #2. The repeater records Operator #1's transmission (for up to 60
seconds). Once Operator #1 is done transmitting, the repeater will key up and playback what it
recorded for operator #2 to hear via from the repeater what operator #1 said. Then operator #2
can do the same thing back to operator #1 and so on.

The main advantage of this playback repeater is that it makes for a good method for an
operator to test their own transmission and quality of audio.

My repeater is open and all licensed hams with 2 meter privilages are welcome to use it
anytime. My only rules are to keep conversations "G" rated and to be respectful.

A DTMF code feature of interest on the Levant repeater...

* Dialing "0" ...will replay the last recorded transmission. This is the "say again" command.

Recent news/updates...

* My brother-in-law and I mounted the antenna to the
back of the garage as most recently planned and the
repeater is back on the air. (10/23/16)
* Due to my brother-in-law, who was going to help me
install the new antenna, ended up having to work a
double work shift this past w/e, I was only able to
start the process. Plans are in place to get this
done on this coming Sunday with not only my brother-
in-law, but my father-in-law as well. Between the
three of us, and weather permitting, we will get this
antenna/system back up and going. (10/18/16)
* Due to family business yesterday and the rainy
weather today, mounting the repeater antenna on the
garage is posponed until next weekend. (10/9/16).
* Due to time restraints, I had to get the repeater
antenna pulled down and away from the tree it was on
so it can be cut down. Plans to mount it to the
garage is planned for this coming Satruday unless
life gets in the way. Otherwise, an upcoming Saturday
where I have a full day off to work on it. (10/5/16)
* With the help of my brother-in-law, we have finished
the installation of the Levant repeater and it is now
active and on the air. (8/28/16)
* I have transported all the equipment needed for
installation of the Levant repeater. Started the
ground work for the antenna. Tomorrow afternoon I'm
hoping to get the antenna up at least 20 feet in the
air. That, along with getting the equipment set up,
my goal is to have it on the air by tomorrow night.
* A low power repeater has been put in place of the
equipment used for the Hermon one. So the Hermon
repeater on 147.120+ is still on the air. (8/20/16)
* The entire setup of the 147.120+ frequency has been
pulled out to make way for the move to Levant
location that will be on 147.360+. (8/20/16)

Upcoming upgrades/changes...

* An unexpected immediate change is pending to be done
within the next week. The tree I have the repeater
antenna attached to is going to be cut down due to
free availablity of a tractor for a limited time
that can pull it down more safely. This tree is
partially hanging over the garage and was originally
going to be cut down a few years from now. The
antenna and mast sections are going to be moved and
attached to the back of the garage. Plus, it may give
me an opportunity to add another 10' section. (10/1/16)
* There are still some minor issues to resolve with the
new Levant repeater. The lightening rod was only able
to penetrate 3-4 feet into the ground before it hit
ledge and the rope that properly secure the mast
sections are temporary. A new lightening rod will need
to be bought and attempted again plus the straps I
bought to properly secure the mast sections will have to
be revisited soon. (8/28/16)
* Big change coming up! The entire system is moving from
Hermon to Levant and will be changing frequencies from
147.12+ to 147.36+ with the same tone. This big change
should be happening by the end of August. Elevation at
this new location will be about 150 feet higher. (7/28/16)
