AMARC SIX METER AM RADIOS FOR LOAN


INFORMATION

In an effort to help promote "Old Time AM Ham Radio" our club has installed a new 6 meter AM repeater on the frequency of 5.4 input, and 5.5 output. And, also to help promote our new 6 meter AM repeater, we will ne having a new net on this repeater, at 21 hours every Sunday night, following our business net meeting at 2 hours, held on our club's 2 meter repeater.

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 5's,6's, and 7's.

The radio will come with a microphone, AC power cord, and crystals for use with the repeater input of 5.4. Also, some may come with crystals for 5.35 and 5.55 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, KRWU, 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 KRWU, 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 1 percent, but I do make an effort to work on them as much as possible.

This radio equipment is 4 to 7 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.


MEMBER REQUIREMENTS

The loan radios, and any accessories, are known as "Equipment".

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 KRWU 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.


OPERATION

I am sure that for the new comers to Ham Radio, that to look at, and operate, these old radios will be a new and exciting experence. And, for us old timers, a trip down memory lane. Personally, I am thrilled with the thought of talking on my old Gonset Communicators. I have been doing so in 6 meter band openings, but they come far and few between.

In band openings you will be able to talk to AM skip stations by simply retuning your receiver to 5.4, and if you want, you can leave your receiver on 5.5, and listen to the skip through the repeater.

They will be hearing you on 5.4 direct from your QTH. You could also ask them to listen to you on the repeater output of 5.5. 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 5.55 simplex, if you want to clear the repeater.

5.35 is not a common frequency, but 5.55 is a military frequency, and many surplus crystals are available, and in use. 5.4 is also a military frequency.

5.5 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.


RADIO ALIGNMENT

Well, operation of these radios is very simple compaired to our more modern radios, but there is one major difference to be aware of. The radio has tubes, and tuned circuits.

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.


LIST OF LOAN RADIOS


The first thing to do is to look at the display radios page. There you will see a list of the type of radios I am presently restoring. If you see one you like you can request that model, and I will try to skedule it next in line.

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 KRWU 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.
