    Its a “Big G” as Gates called it. The older “T” had the triangular viewing window, and the newer “H” had a rectangular viewing window across the door. The 833A were arrayed left to right in the “H,” a configuration seen in the 1950s “J” model and older.

    These were marketed to stations that were licensed for 1,000 watts, and typically also had a “nighttime” or pre-sunrise power authorization of 250 or 500 watts. There is a power reduction setting and circuitry to accomplish this. A very similar model is the BC-500, which has only a single 833A in the fnal.

    That buzzing around 3:15. I hear that here in the states, too. I don’t hear broadcast, though.
    Thanks!

    That right window’s colors represent the strength, I think. It might be age. The calls are listed lowest frequency at the top and highest at the bottom.

    Thanks I will let my Dad know, he also thought the buzzing 3:15 was something to do with the building next door but if you hear it in the States as well, it is not them next door to us at fault.

    Tnx for the video – I’m just starting in this and it’s been helpful. Yes the colours represent how long ago the signal was last heard. There’s some good stuff on the K1JT website including a manual.
