Chelsea Yaesu DR-2X Repeater Setup
Wesley Cardone, N8QM
July 3, 2022
Testing and Scheduling Procedure
The repeater has been programmed to receive and automatically determine the nature of the received
signal. The received signal can be
1.
Analog FM
2.
C4FM Fusion digital
Further, there are transceivers that are bi-modal such as several Yaesu C4FM capable transmitters. It is
necessary to verify that such C4FM radios will operate properly when set to:
1.
FM only
2.
Auto detect FM vs C4FM
3.
C4FM only
The mode dichotomy together with transmitter options therefore defines a large number of
permutations. Not all of the permutations need to be tested. I have listed below the permutations that
are likely to be relevant. We will substitute the Yaesu DR-2X for t
he Hamtronics at Don’s house and
perform the following testing.
1.
non Yaesu (Analog FM)
--
non Yaesu (Analog FM)
2.
--
C4FM enabled
3.
--
C4FM capable but set to Analog FM
4.
C4FM enabled
--
non Yaesu (Analog FM)
5.
--
C4FM enabled
6.
--
C4FM capable but set to Analog FM
7.
C4FM capable but set to Analog FM
--
non Yaesu (Analog FM)
8.
--
C4FM enabled
9.
--
C4FM capable but set to Analog FM
10.

Remote control is accomplished only using (a) transceiver(s) previously registered with the repeater. The present
plan is to register Jim’s and Wes’ Yaesu FTM
-3200D transceivers with the repeater. The WD8IEL implementation
adds a double layer of security using an unpublished control frequency that must be used to transmit the
commands. In both transceivers, a memory location will be added where the correct frequency, modulation mode,
and sub-audible tones will reside. This facilitates an easy and quick way for both Jim and Wes to send remote
commands
to the repeater. Only those person’s having a need to know will have the frequency.
