From FCC Part 97

(b) In addition to one-way transmissions specifically authorized elsewhere
in this Part, an amateur station may transmit the following types of one-way
communications:


(1) Brief transmissions necessary to make adjustments to the station;
§97.119 Station identification.
(a) Each amateur station, except a space station or telecommand station,
must transmit its assigned call sign on its transmitting channel at the end
of each communication, and at least every ten minutes during a
communication, for the purpose of clearly making the source of the
transmissions from the station known to those receiving the transmissions.

So you have 10 minutes before u need ID

I'm working on my first HF antenna. Hand-built for 10M, it will be --
and
on the air as soon as I'm legal.


Speaking of legal, when I'm doing low-power antenna tests for matching,
what's the protocol for ID'ing? My antenna experience is limited to FM,
where I easily ID through the mike with one hand while twiddling the SWR
meter with the other.

However, if I steady-key on HF to measure VSWR, I obviously can't ID; if I
use voice, the needle's bouncing.

Does the HF community tolerate occasional non-ID'ed transmissions for
essential testing????
