Store & Forward 2-meter Repeater

147.120 Mhz | + offset | 77.0 hz CTCSS

Status... "Active"

View this photo in it's original size along with
additional photos I took of the entire setup.

You will find my repeater on bandplan frequency 147.120 Mhz with a positive offset. You
will need to be transmitting a 77.0 hz PL tone to access it.

How does my repeater differ from most other ones? It is a digital audio store-and-forward relay
system. It lets two operators, who are too far away from each other to communicate to one
another using either the same frequency OR by offset.
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 TX and playback what it
recorded where operator #2 might be in better range of the repeater to hear what operator #1 said
as it does the playback. Then operator #2 does the same thing back to operator #1 and so on.

Besides using this repeater as a store-and-forward system, it also 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 2m privilages are welcome to use it anytime.
My only rules are to keep conversations "G" rated and to respect one another.

The only times I have it disconnected are during on-the-air nets that I check into and if
I am engaged in a QSO from my home QTH. But most of the time, it is active.
