UHF LTR (Mt. Rigaud)

[DaveH]

Recently west of Ottawa (between Ottawa and Montreal) I've heard UHF LTR on 463.925 and 452.8625. The Industry Canada TAFL database lists it as Mt-Rigaud (Rigaud Mountain) with two other frequencies 451.050 and 463.700. I did not hear idle bursts on the last two channels.

The burst period is about 3s and duration is longer than the usual for LTR, so I wonder if it could be Passport (Eric C., if you're
in the area, you may want to check it, if you're inclined, and I know you are...).

How long between the data bursts?? On some Passport LTR's some of the data bursts are of longer durations... On the Adams County E-911 District Passport LTR, their is about once every ten seconds or so on one or more of the repeaters, a 3 or so second long burst. This is in addition to the usual every 2 seconds quick burst.... Possibly this indicates an MDS?????

Possibly this indicates an MDS?????

The period (interval) is about 3 seconds. The duration of carrier+data sounds a bit more than 1/2s, longer than LTR (I once measured about 1/3s on a 'scope).

Thats LTR Passport

I think it probably is. They're usually too weak to copy at home, but recently were coming in strong early in the morning. I could not get any regular LTR decode using the PRO-92; didn't get a chance to put Ltrtrunk on it
