Amateur Extra: HF Space Station Allocation

Amateur Extra: HF Space Station Allocation

The Amateur Extra question of the week comes from the section on frequency allocations and amateur services… [E1D07]

Which amateur service HF bands have frequencies authorized to space stations?

A. Only 40m, 20m, 17m, 15m, 12m and 10m
B. Only 40m, 20m, 17m, 15m and 10m bands
C. 40m, 30m, 20m, 15m, 12m and 10m bands
D. All HF bands

Ah, man.  There is no good way to put this, but this is yet another question that you just have to memorize.

The correct answer is A. Only 40m, 20m, 17m, 15m, 12m and 10m.  Why? Because that’s how its defined in Part 97, section 207 of the FCC rules.

(c) The following frequency bands and segments are authorized to space stations:

(1) The 17 m, 15 m, 12 m, and 10 m bands, 6 mm, 4 mm, 2 mm and 1 mm bands; and

(2) The 7.0–7.1 MHz, 14.00–14.25 MHz, 144–146 MHz, 435–438 MHz, 2400–2450 MHz, 3.40–3.41 GHz, 5.83–5.85 GHz, 10.45–10.50 GHz, and 24.00–24.05 GHz segments.

Recall that HF only includes bands from 10m on up, and there’s your answer.

The truth is, if you’re even concerning yourself with working space stations on HF, you will know this.  The only other reason to know this, is so you don’t miss this question on the test!
