And, as an additional insentive to promote activity, Our club will be lending out to all
club members, old reconditioned tube type 6 meter radios that were mostly used for general ham use,
and Civil Defence use, back in the 5Ø's,6Ø's, and 7Ø's.
The radio will come with a microphone, AC power cord, and crystals for use with the repeater
input of 5Ø.4ØØ. Also, some may come with crystals for 5Ø.35Ø and 5Ø.55Ø for simplex use.
These old radios have a tunable receiver, so no crystals are needed to receive.
This equipment is being made available for use by the Ancient Modulators Amateur Radio Club
members, by Paul Schlipp, KØRWU, and after signing of the radio loan agreement for the equipment, the AMARC club member
will be allowed to possess, and operate this equipment, for an indefinate period of time, with
no charges envolved, as long as the club member does not abuse the equipment, remains a AMARC
club member, or KØRWU, or the Club, wants the equipment back.
These old radios are being reconditioning as fast as possible. I can not devote my spare time to
the task 1ØØ percent, but I do make an effort to work on them as much as possible.
This radio equipment is 4Ø to 7Ø years old, and not manufactured any longer, and many of the
parts are not available, So please treat the radio carefully, and I am sure it will perform for
many more years to come.
Hoping to prolong problems, as I recondition them, I am adding fans to the tube radios.
The club members are not allowed to perform any repairs, or modifications to this equipment.
All equipment problems must be reported to a club officer, or KØRWU as soon as possible.
The applicant club member is responsable to pick-up, and return the equipment to Paul Schlipp
when repairs or required, or when the equipment is no longer needed, or to be swapped for a
different radio.
The applicant is required to install a 6 meter outside vertical antenna of some sort. A good
ground plane would be best, but something as simple as a copper wire vertical dipole will surfice.
It may be of interest to some of the members to try different makes, and models, of these old
radios.
If you want to try swapping radios with other members, you must make arrangements through Paul.
In band openings you will be able to talk to AM skip stations by simply retuning your receiver
to 5Ø.4ØØ, and if you want, you can leave your receiver on 5Ø.5ØØ, and listen to the skip through
the repeater.
They will be hearing you on 5Ø.4ØØ direct from your QTH. You could also ask them
to listen to you on the repeater output of 5Ø.5ØØ. Then you would both be using the repeater.
If you get 2 skip stations to do that, they may be hearing each other when they would not be
able to, and maybe never, because of being too close for skip, and too far from each other for local ground
wave.
You can also ask them to switch to 50.350, or 5Ø.55Ø simplex, if you want to clear the
repeater.
5Ø.35Ø is not a common frequency, but 5Ø.55Ø is a military frequency, and many surplus crystals are available,
and in use. 5Ø.4ØØ is also a military frequency.
5Ø.5ØØ is not a common frequency. Of course someone with a VFO can go to any frequency.
Operating with crystals are how us old timers did it. Mostly because VFO's were expensive.
If a tube transmitter is not aligned properly, you can damage the out-put tube in a hurry.
Now, most of these old radios are low power, around 15 watts input, but they can still get damaged if not tuned properly.
Most all of these old radios have some sort of tuning indicator. The ones with a peaking meter, or tuning eye tube, are
easy to tune, You simply tune all the stages for max. indication.
Some only have a plate current meter. This is where you have to tune final resonance for a dip in plate current, and then load
the antenna coupling for more current, and then re-dip untill you reach the manufacture max. current reading.
For these type radios, I strongly suggest a SWR bridge, or wattmeter in line and tune the stages for max. out-put.
Also, there is a list of microphone types I have in stock. You may also select a choice.
Of course there is a list of completed radios you may select from. Presently I am working on the Lafayette radios, and a few Gonset Communicators.
If you see a radio listed and want to borrow it, please contact KØRWU
with your radio model choice.
You will be required to sign a loan agreement, and have a 6 meter antenna available.
There are no funds involved, but the loan agreement is mostly to protect the
property.
