I am not turning it over. Access to it is as it has always been. If somebody
wanted to use it in the past, they could have used it and blown it up as
easily as they could now. The only difference now is that we have removed
the added extra complication of moving the cables around. I have not changed
any policy that the club has whatsoever. People should not operate things
they don't understand. I have just made it easier for people to operate in
the easy mode (and easier to understand). In the past, people were
intimidated from using the radio at all because there were no instructions
on how to do so. I really think you should read what I said again. In the
easy mode, they can't blow anything up. The tuner takes care of everything,
and if the tuner can not achieve a good match, the radio folds back if there
is a bad mismatch and protects the final amp.
I would also prefer if you would stop referring to donated items as if they
are still yours. I don't care how much you paid for them, they are now club
property and nobody wants to have them destroyed. You don't have a monopoly
on concern for the items.

dave, i think u r making a mistake turning the hf amp over to the general
population, that's how it got blown before. u should be requiring a check
out on this item. if a member is serious about using it , he/she will be
quite willing to get checked out. we are not going to turn over the vhf
ssb gear
to the general population at this time, it is not ready and fool proof yet.
george bernard w6nre ps: i am willing to go up to the club and brief
properly qualified operators on the idiosyncrasies of this expensive gear.
i dont want the amps blown out due to over driving, i paid a lot of money
for them.
one of our new techs might make a mess of things unless properly briefed on
how things work, i am sure john portune does not give experience in his tech
classes.

All
We finally have a nice shelving system to accommodate are ham shack at the
club. Thanks to Bob for the fine craftsmanship. It looks and functions
terrific. Assembling the station to its final configuration will take time
and money, but one of the HF operating positions is available now for
general use. It will accommodate simple use with the auto tuner, or complex
high power operation without moving cables around.
Here is the FT-840 station. A paper copy of the manual is available for
reference at the operating position.
All that is necessary to operate the station in the "simple mode" is to turn
on the tuner mode on the radio, and ensure that the amplifier is off and the
tuner is in the "coax 1 direct" mode, as shown in the terrible cell phone
pictures below.
Amplifier is off. The PWR and OPR buttons are pushed in on the lower part to
OFF and STBY respectively. This effectively bypasses the amplifier.
Tuner mode is "Coax 1 direct" so that the tuner is bypassed.
That's it. The radio is now ready for tune and play operation with the auto
tuner turned on. Here is the section from the manual on how to operate the
tuner
For the time being, the B&W folded dipole is connected to the station. It is
the best all around performer. If you want to change it, you can connect a
different cable to the tuner where the current one is. For those of you that
want to operate the amplifier, be advised it has a parasitic oscillation
issue that you need to be on top of. I am going to order a cheap kit to
solve this issue. If you want pointers on how to use the amp, just ask me.
In the long term, we plan to have an antenna switching system that will
allow both stations to operate all of the antenna with a simple selector
mechanism. I will probably send out an email later describing that effort.
On another note. All three computers in the shack are now operational, and
the printer is also working for both of them. Thanks to all that donated
monitors and keyboards.
