I do not know anything about this repeater, but......on my 440 repeater with an old ACC RC-85 controller, I have a Kenwood TS-440 transceiver interfaced with the repeater. By entering the proper "turn on code" from a touch-tone mic you can turn the HF transceiver "on", change bands and frequencies, receive a voice mode and frequency "read out" over the air, and operate SSB on any HF band by using a 440 FM transceiver through the repeater.
My HF antenna is just a trapped dipole, but it works very well at 250 feet.
It is nice to be mobiling to work, bring up the 440 repeater, turn the HF transceiver on via touch tones, set a band and a frequency, and talk SSB to the other side of the world from a 440 FM transceiver.
Maybe the repeater you are listening to has a similar set-up.
