You will find my repeater on frequency 147.360 Mhz. It uses a positive offset and
uses a 77.0 hz sub-audible tone in and out for access.

How does this type of repeater differ from most others? 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 distant operators to be able to communicate to one another.
It just takes double the time 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.

Another advantage of having this type of repeater available is that it creates a good method for an
operator to test their own transmission and quality of audio without taking up a second operator's
time. Plus avoiding the confusion of another operator trying to describe how you are sounding.

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


News & updates about this repeater...

* 5/19/19 - I noticed that the power output has deminished
greatly. My guess is that the RF Concepts amp must've quit.
Life has been and still is quite busy outside of ham radio
so uncertain when I will get around to troubleshooting it.
It is still working but on some form of low power.

* 4/28/19 - I decided to uninstall the Amazon Echo device.
Mainly due to needing it elsewhere non-radio related. For
the short duration I had it installed, it did work well.

* 8/15/18 - I installed an Amazon Echo device with certain
ham radio related Alexa skills to my repeater. For a while,
this will mainly be deactivated as I find time to fine tune
it the way I feel would work best. My plan will not be to
make a wake up word to shout out over the air but rather set
it up to periodically announce valid information such as
local weather forcasts, ionospheric conditons, space/sunspot
weather, and ham event reminders. I expect to have this
completely implimented by the end of the year.

* 9/13/17 - After a few days of testing, my 147.360 repeater
is back on the air. Trickle charger failed and was replaced.

* 8/1/17 - I noticed that my 147.360 repeater is offline and
not working. Uncertain as to when I will have the time to go
to the site to troubleshoot the issue.

* 4/15/17 - Local NOAA SAME alerts were added to my
147.360 repeater.
