Hello Orioneers?
Im a recently late comer here, so hope this posting wont be a repeat?
As a RTTY DXer I often have reason to work split. I discoverd that the Sub
reciever readout is not shifted by the FSK button. The passband is shifted
correctly; but the readout does not follow. Therefore the reading is
incorrect by roughly 2.2kc
This means that in split operation using the sub reciever to listen to the
pileup? You will not be listening where you are transmitting. You can
workaround this by cranking in +2270 hz on the subreciever RIT. You should
verify this setting by checking the two recievers for zero beat with a test
signal. I dont know how consistent the RIT numbers are, from radio to radio.
Tentec was unaware of this particular glitch. Paul Clinton had their
Engineering department verify the condition, and obtained a commitment from
their software engineer to fix it in the NEXT issue.
I have dedicated USER 2 to remembering the RTTY parameters, so that upon
calling it up, all the common RTTY frequencies have the +2270kc offset in
the sub reciever.
This condition has been verified to exist in two other late ORION s. All
three with version 1.372. I dont know about earlier versions.
73 and RTTY forever
