[Lf] Part 5

Hi Andre', Kristjan,
As far as I'm aware, there've been a couple of Part 5 'ham-like' activities focussed on the
500kHz MF area.
A guy in Colorado got a licence for a 480kHz beacon a couple of years ago; dunno if
that's still on; probably died of boredom. The other was a bit more ambitious, being a
multi-station licence (twenty-odd, maybe more) calling themselves the Six Hundred Metre
Radio Group, or 'SHMRG' for long. They were initially granted a number of MF
frequencies including 480kHz and a couple at LF, and there was much rejoicing in old-
tyme radio-land until the US Coastguard found out what the FCC had done, turned all
kinds of purple and got all but a (fairly wide) allocation at 166.5kHz revoked.
To date there have only been (I believe) two of those stations make any noise there at
all, with one guy down in Louisiana still valiantly beaconing. The wind well and truly got
taken out of their sails.
As much in righteous indignation at the FCC's recent stunning decision as anything, there
has been huffing and puffing lately in Lowfer-world about possibly getting a mass Part 5
application together. Since communication with 'other services' is apparently not a typical
feature of Part 5, and international communication an almost certain no-no, it is a bit
difficult to see what advantage there would be; essentially just doing the same things,
but louder. That said, I'll certainly sign up if it takes shape. I need a good laugh, and
high-power LF with the fireworks attendant might be worth a few.
Cheers,
Steve
