Philco 42-350

Post by Ben Delk on Mon May 14, 2012 2:42 pm

Came across a Philco 42-350 for $20 last week so I said "what the heck? Recapped and replace some rotten bushings and now it play A.M. very well but I cannot get FM. I was reading an article about the radio stating
the FM station were assign by the FCC but not license while this radio was in production. Humor me here but before I start digging around trying to find a solution, does this radio play FM stations?

What aree the frequencies on the fm dial? If it's the old fm band, it's no longer used. Sounds like it might be.

BC 42 to 50 mhz. It would appear the FM is nonexistent in the year model 42-350. FM stations became obsolete by the end of WWII.
What about SW...SW covers 9 to 15 Mhz, with high sensitivity. Is it picked up on a standard areial?

That was the old FM band. It stopped being used after 1960, I believe.
Some SW bands are no longer used, but, most are. I get alot of sw on my GE J-805 at night.

I was able get several SW stations late last night, seems they were are Latino. Since you are on a roll here.....Must of the AM stations I receive are loud and clear but a couple even though they are loud and clear they chirp. Is this must like internal(electricalcomponent) or external (electrical interference, feeback, lighting, etc...)

Lightnning would be loud, drowning out static, varying with pitch, and, frequency, depending on how manny strikes, and, how near.
Chirping, if you mean a squeling that goes in oscilation, sounds like it may be your radio oscilator.
Could mean your radio needs a better alignment.
Placement of certain componnents, especially in the oscilator cicuits can be crittical.
Also, certain things, appliances, etc., can cause interference. Coputers running, even in the same room can rais a havic with am radio, as can television.
The modern cfl light bulbs create their own noise, as do florescent lights.
I have even seen two radios playing in the same room where when one is tuned near the same frequency as the other, will cause harmonic noises, and, make at least one of the radios get a loud squeel.
Hope this helps some.

No lightNing involved just lighting. I do have lots of elecrical in the area and a laptop with wireless within 2 feet of the radio, I'll try removing it. The sound is not like an ac hum or sequlc or squeel. It sounds like a baby bird chirpping. Oddest thing.

All the documentation I can find states the pre and post WWII FM stations were unlicensed by the FCC and when the FCC got around to licensing FM the FM station were in a different frequency range so the old one no longer exist.

The old FM band picks up the EMS & FD in my area on 46.1 Otherwise, I use a converter to pick up the modern band. It sure wakes up the sound on these old FM sets.

What type FM converter are you using. I recently purchased am "i A.M. Radio" a.m. broadcaster so I can pipe cd, mp3, streaming radio thru the old radio. Man I love that thing. Thanks for the reply.

Ben,
I'm using a reproduction of a Scott converter I made from the info I got on Nostalgia Air. It wasn't too hard and worked well. There are simpler ones on this link:
http://somerset.net/arm/fm_only_converters.html

Also there is more info on the real history of the FM band here:

have fun, Bill

I was able to find a 42-355 a short while back on Ebay. Also found the instruction manual for it in another auction. It is the equivalent of a folded sheet of 10x10" paper with nary a sign of a technical writer. Hope to gather the things needed for it to work on it during the colder weather.

SW bands are all still being used. SOme are active more in the day, others at night. Besides Spanish stations you should be able to get all kinds of English language bradcasts. I regularly receive Voice of Turkey, Bulgaria, Taiwan, China, Cuba and many others, all in English. Even if you don't understand what the language is, you can still hear some of their local music, some really interesting sounds.
I don't understand the "chirping", perhaps post a small recording. There are some strong broadcasters that almost overmodulate and combined with atmospheric conditions, fading etc. so it may sound unnatural at times. Part of listening to SW. I really doubt it is in your radio.
19 and 41, why not scan that pamphlet and post a link to the full sized inages? We'd love to save a copy.

As far as the low band FM, many states still have agencies that use that band. California CHP still uses 42 mhz, other small FD and Sherrif offices use the low band.

Glad to help. Starting to get together items to do the 42-355. This new Rider's and Beitmans' dvd-rom is as clear as my Philco year book.

Not the user's guide. I found the one I posted on ebay. I just made a bookmark of a tube radio search under the model number. You can find manuals, hang tags and all kinds of ephemera at various times.
