The range in the video is supposedly audible on 28.210 MHz and they'd like to do a full-up recreation at 529 kHz.

If you're one of the Covidiots who believe that COVID-19 is "just the flu",
that the 2020 election was stolen, or
especially if you supported the 1/6/21 insurrection,
leave now.

The last time I flew a 4 course range was in Alaska in the mid 60's. I flew a Cessna 170B from San Antono Tx to Eagle Alaska , with a LF receiver and a Narco MK 2 Ominigator. When I would check in with the various tower and approach controls you could hear the gears slip when I would contact them that I was transmitting on an alternate frequency and listen on the VOR. That is just not taught any more.
ReplyDeleteNot in the training manual is what we would call an Alaska Instrument approach, you are on top of the cloud deck, the ceiling at the airfield is reported to be 500 feet or greater, and the field has a NDB located on the field. You would fly a clover leaf pattern to identify the cone of silence that existed on top of the antenna, and when you where sure you were on top of the antenna you would put the aircraft into a spin, spin down through the clouds and stop the spin as you came out of the clouds and then circle the field to land. You hoped that you did not pick up too much ice. What the hell we were young and dumb.
28.210, huh? I wonder how they got authority to use that frequency. That belongs to us hams.

28.110 beacon is managed by hams, so they can do that. I checked my log and I've even worked those guys on 10M.
ReplyDeleteOddly this is one area where hams are still actively researching. Doing it at HF instead of LF makes it easier to build the antennas and trnasmitters. Back then anything over a few MHZ was way up there, nearly beyond what the tubes of the day could do and deemed useless. Now of course its trivial they are also finding there are fewer propagation caused errors at the higher frequency, also less static and noise. The advantage is there are cheap portable radios that can pick that signal up even on 10M.
That and if all things go SHTF it's
tech that can be built out of junk laying around like old computer monitors, a few AM CB rigs and some knowledge of how it was done.
Eck!
Very cool and very clever.
ReplyDeleteGreat find!
Bob, how did passengers feel about an instrument approach that required spinning down through an undercast?
For Nangleator;
ReplyDeleteWe mainly hauled cargo, mail and locals. The locals had no problems, and if we were hauling oustlanders (typically hunters) we would brief them on what we might have to do in order to arrive, the description would not come close to the actual event. Usually the hunters had buck fever so bad that you could tell them that would have sit naked on hot coals for the flight out they would do it. Sometimes there would be a group, and one or two of them would be a cherry, and his buddies were setting him up for the experience.
There were times when we would get out to the village only to have to divert to Tok, or Talkeetna, Fairbanks, or Yellow Knife, God then you would get an ear full.
