[Milsurplus] AN/ARC-8(?) (ART-13B + ARR-15)

[Jim Berry]

Hi Group,

I also am not up on all the radio's that were used in aircraft.  I
sure am learning though.  I guess my main interest is in old WWII
Navy shipboard gear.

I did some more digging, and found that receiver was often tuned to
an RTTY channel, where it fed a converter, and MITE tty machines.

Now that makes more sense.  That means that a pilot could not only
select remotely the transmit freq, but the receive freq also.  I do
not even know what a AN/ARR-15 looks like, or it's tube line up.  If
someone can send me some info, it would be appreciated.

I don't.  I like to listen to my signal as it sounds from the
transmitter.  In most cases, just grounding the antenna to the
receiver is enough.  If that is not enough, there are tricks that can
be pulled.  It does usually consist of a second RF gain control, etc.
Doing such things, without hacking up a radio is half the fun.  One
has to "tack" wires into place, and sneak them out through a louver.

I do use a keyboard, with squalled state components, to send CW.  I
have found the ART-13 to be a very nice CW rig.  I can get 25 wpm out
of mine before I have to start dialing in some weighting.  I love the
sound of thrashing relays.  Many don't though.  I also try to operate
QSK in almost all cases.  To do such, you do have to do some fiddling
with your receiver.  Again, the trick is, to do this in such a way as
to not have to "hack" the receiver.  It can be done.
