This phone should keep my PTT Standard phone company.

Dig that crazy cradle, man!  Post some photos when you get it all cleaned up.

The cradle on this phone is similar to that of the Kristian Kirks phone I bought several weeks ago.  I guess it's a northern European thing.

Hi Lary,

The ones with a lock on the side are quite rare. The lock interrupts the dial's pulse  contact.

Let me know in case you need a schematic.

Hi Larry,

I might be able to get you an original handset cord in case you need one.

The phone arrived this past Wednesday.  I cleaned and polished it (it was really filthy), and added a dollar store handset cord.  An original cord would be nice, but I don't really want to spend alot on the phone right now.  I figured out the purpose of the lock switch on the side.  In the locked position, the switch would shunt the pulsing contacts of the dial, preventing anyone who couldn't figure out how to unscrew the base from dialing out.   I was not aware of how common or not these were.

The phone works, except that, like several other phones that I have bought, the transmitter produces static.  For now, I put a T1 in its place.  One of the interesting things about this phone is that the finger wheel is made of bakelite.  I do not think I have ever seen that before.

I hope to take and post some pictures of the cleaned and polished phone some time this week (if we have any sunshine).  In all, I think that it was worth the $1.04.

Hi Larry,

Did it come with a key?

Larry,
If the transmitter has static, take it out and give the edge a couple of good taps on a hard surface. This will loosen up the carbon. I've seen it done and it works.

Dougpav,

I have tried that on this transmitter as well as others, but it has not eliminated the static.  I don't know what I am doing wrong, but I have at least five transmitters with static problems from various phones.  I was thinking about starting a post about the issues in the troubleshooting section.

I think some of the European and Japanese transmitters are more delicate than we are used to.  I once suggested to Brinybay (Greg) to do the tapping routine on a transmitter from either his NEC or his European phone (I can't remember which) but I seem to recall that sent the transmitter to the junk drawer.  Maybe Remco, GPO or DSK can weigh in with their experiences.

If tapping does not work, and the problem is indeed the transmitter and not wiring, or switch contacts, I don't know of an easy fix.  Transmitter surgery is not for the faint of heart.

It is often possible to retrofit a T1, an F1, or an AE transmitter in place of some of these without too much mechanical meddeling.

Hi Bill,

Never even thought of "shoogling" (thats a Scots word = shake)  the carbon, I have that many spares from junkers just replace em.

On a similar note, my Palco 500 had a quite muffled sound from the trans, so I swapped it with my black 500, still the same.

Was gonna buy a new one from Phoneco, but decided to try replacing the base cap it sits in from the black 500, now it works fine, but totally puzzled as to how something as simple as a bit plastic with two screw terminals can affect the performance of the trans?

Maybe in the process you inadvertantly "solved" the problem just by tinkering with it.  Has happened to me many times.  Try putting the cup that "caused" the muffling into another phone and see if that happens too.  Maybe the contacts were dirty?  Sounds like a total mystery to me.

I was able to place a T1 capsule into the handsets of both the Dutch Ericsson and Danish Kirk phone without any modifications other than bending the contacts a bit.  Both of these phones have transmitters almost the same size as a T1, but with different contacts on the bottom.  The T1s just barely made contact properly.  In my Kellogg redbar, the transmitter was also very noisy, so I connected a T1 with wires soldered to it and spades on the other ends and placed a bit of bubble wrap under the capsule to help position it properly.  The Kellogg transmitters have a much different size and shape and totally different contacts than T1s.  The arrangement is kludgey, but it works for now.

I think that tapping (or banging) the transmitter capsules is helpful to loosen packed carbon granules.  When the carbon is packed, the granules cannot move freely enough, so the efficiency of the transmitter is compromised.  

Regarding gpo706's muffled transmitter.  My first guess would be that there is too much oxidation and/or dirt on the contacts in the transmitter cup.  I always clean the contacts on both ends with electrical contact cleaner and usually sand them lightly with fine sandpaper.  I also usually bend the contacts in the handset upward a bit so that they will make better contact with the capsules.  I have found dirt and oxidation on transmitter and receiver contacts to be the biggest cause of static and weak sound quality.

Yes, Bill and Larry, that makes sense, how a 1959 transmitter cup works better than the 1984 refurb on the Palco is a bit mad!

Thanks for the tips.
