In the Early 70's for FD we had a loop that ran on and old open reel aprox 3 1/2 in reels . We had built an audio decoder (rectifier) that was used to key the CW for CQing. The CW had a bit of humm from poor filtering of the rectifier ckt but it did work.

In the late 1960 at VE5US, the University station, we had a punch paper tape loop that was used to drive some electronics to do automated CW CQing

Back in the 80s sometime, I had a30-second answering machine cassette
recorder, followed by a circuit that rectified the audio and amplified
it to switch a relay for CW CQing.  Worked fine, but pretty inflexible.
I'm glad those days are behind us.

Back in 1960 I rigged up an endless tape loop which I ran through a Wollensak tape recorder (which, in true ham fashion, I still have). To maintain tape tension I draped the tape loop over the back of a chair and wrapped a few turns of #14 bare wire around it to act as a weight.

Fed the output of the recorder into my 100V and let the VOX take care of turning the TX on and off.

Worked FB for calling CQ. One day after I'd been CQing into a pretty much dead band for a couple of hours I got a visit from a Radio Inspector who was wondering what was going on. I proudly showed off my Rube Goldberg contraption. He clearly didn't like it and told me to stop doing it. When asked what part of the Radio Act I was contravening he simply told me again to stop doing it. Well, I was pretty young then and lived in terror of the licensing authority so I guess I stopped doing it.

The discussion on improving voice recordings for phone got me to
thinking about where we have come and where we might go.

Long before digital voice recorders (DVK's) the astute SSB contester
discovered the voice loop tape for diskette players.  These loops ran
from a few seconds to as long as 16 seconds and were designed as
telephone answering devices.  I used one for years to call CQ and the
last time I used one extensively was in the CQ WW SSB in 1979 to win the
USA 40 meter Single Band.  I tried to use it in the 1984 ARRL DX SSB on
QRP but found that only on 10 meters could I get answers to be worth the
effort.

In 1985 I found Nel-Tech designed by the fellows who designed the Wang DVX
and I laid out good dollars and brought the Nel-Tech 100 home. I used
it in a few contests and N5KO was living in Atlanta at the time took it
to N4RJ to use for Single Operator in the ARRL SSB SS.
It did appear in a voice monitor that there was some hum so he stopped
using it and lost his voice on the second day.

Next I bought a MFJ 432 and found that you could cascade a pair for more
options.  This worked well for me in the CQ 160 SSB in 1994 as I won the
Zone 5 Plaque.  You had to watch as it you pressed a button wrong you
wound up sending an extra first letter.  I wonder how many logged
KK4JRB.  When they were first introduced they worked fine on what you
had recorded but would not let you send straight through.  Tom, W8JI
came up with a fix to correct and those of us with early MFJ 432's got
Rev 1 which corrected the problem.

A number of hams experimented with the text to speech programs but as
several pointed out using a different voice to send the report caused
all sorts of problems.

Jamie Dupree NS3T, who uses his voice as the Washington reporter for WSB
radio decided that he would take the DVK to the next step and program
.wav files so he could run an entire contest without speaking except for
a few corrections.  He published an article in CQ on the subject.

Digital voice could be the future.  But so far the steps have been
stumbles. Henry Radio sold the 300 but you had have one at the other end
to work correctly.  AOR tried two models several years ago but again you
had to have a unit at both ends.  D-Star from ICOM so far is just a VHF
device.  The problem is that there needs to be a standard decoding so
the various interfaces can make digital voice be just another digital
mode.  This can help with the QRM on the amateur bands but you still
need a way to have a set of exchanges to send.

We have come along way from flipping a toggle switch or using PTT for
phone contests.  I went straight to VOX when I went on SSB on Jan 1,
1960 and have not looked back.
