Amateur Transmitting Station OA-7PF

    TATION OA-7PF has been in ope-
     ration since June, 1925, since when
     many changes have. taken place in
the layout and the gear used. The pre-
sent photo shows the gear that is in
use at this time. Reading from left to
right there is the power-supply board,
orr-the left of which are the H.T. and
filament supply switches for the big
transmitter. In the top centre is the
H.T. voltmeter, which shows the vol-
tage being delivered to the same set,
while immediately below this is the
motor control switch for the motor
which drives the 1 k.w. D.C. generator.
On the left of the board are grouped the
H.T. and filament supply switches for
the small transmitter, together with the
motor starting switch for the motor
which drives the 500 volt D.C. gene-

of the board on a shelf are arranged the                                      q The Outfit at OA-7PF.

    Are Seventh District Stations Overlooked.?|

     stations are coming in now at very good
     strength, but it is almost impossible to
     raise them, as they all seem to be hunt-
     ing after DX and do not bother about
     stations in their own country. What has
     become of the R.C.C.? Has it died a
     natural death? Most of the mainland
     stations have been coming in here at
     max r, and I learn from my friend Watty
     (7DX) that the period of from three
     days prior to the appearance of the new
     moon to three days after it has gone,
     signals can always be counted on as
    .being at their best. Why? The hams
     in the north have been rejoicing in the
     visit of 7DX to their midst on his way
     to Adelaide to attend the convention.
     During his stay in Launceston he was
     the guest of 7CS, and, needless to say,
    spent most of his time in the shack.

cannot be heard now. Perhaps it is due
to one of those periods of fading, or
perhaps it was an unlicensed station, and
the owner has been caught and jailed.

his “ivy” aerial. By that I mean an
aerial that creeps around the house and
