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.

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.


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 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)

Upcoming upgrades/changes...

* Sometime within the next few months, I am also
looking to add something very unique. An Amazon
Echo Dot device. Click here to see a video about
it. Uncertain whether this will become a permenant
installation but looks promising to experiment with
and if it doesn't get abused. (1/9/17)
* Sometime within the next few months, I am looking
to add NOAA weather radio SAME alert broadcasts.
I am currently testing the device that will be
installed to be sure I have the correct county codes
added. (12/30/16)
* I am looking into either adding or replacing the
commercial power trickle charger with wind power
sometime in the summer of 2017. At some point this
winter, I am planning to purchase 1 or 2 mini wind
turbines that can be mounted part ways up the mast
holding the repeater antenna. Then having it/them
connected to the solar panel charge controller.
Then, between those two, I may completely eliminate
the commercial powered trickle charger and allow
my repeater to be completely off the power grid
and independent. (12/29/16)
