chronic radio interference model 60mb
#1

Hi I'm currently getting chronic interference on this radio in the morning through midday. cant use radio at all, radio fine at other times......I live next door to a shop where i can only assume this is emminating from. as they prepare food so microwaves will be used etc
. can anyone suggest anything i can do??? to get rid of the interference extremely loud and persistent buzzing sound is all i get on all stations on the dial.
I obviously cannot ask them to stop using their equipment...wouldn't go down too well with them!

I once went to the market with my mom, and whe wanted to select a cantelope for dinner. The Vegetable man asked what time she would have dinner if today, and if the melon was for desert. He chose a fruit, touched it with his old hand and pronounced it good. 'Twas.

Talk to your neighbor, and also your utility, and last resort FCC. Of course, sanity check, try a modern portable radio before you haul out the big guns.

Hi Terry,


I should have mentioned I am a complete novice to this.

This radio, I purchased from the US, I live in the UK, The guy I bought it from fitted a 220v transformer so that the radio could be used in this country.

It has only twin, live and neutral cabling.. Should I earth(ground), the chassis, if so, to which part of the chasis should i ground it and swap to three prong wire.

Terry could you also suggest a book for complete novices like me who wants to learn more, safely, but without blowing myself up!!!

Hi Dave,
Good the chat with someone from Wallace and Grommet land. You should ground the metal part of the chassis. You could try attaching a .01@600v cap to the hot side of the mains to the chassis to see if that helps. I'm suprized you didn't hold out for a model 66MB. Same cabinet but has much better shortwave coverage like 6-12mc instead of the worthless 2-3.5mc.
Don't know of a good book for repairing but if you are interested in theory and construction The Radio Amateur Handbook is great. Just have to get an old one from the mid '30's- '50's. Easy to find on epay.

Hi Terry,

Grateful thanks from over the pond!

Grounding the chassis has done the job!!!

If I need advice in the future I'll ask you.

Will look out for the book on ebay.

Glad the grounding did the trick for you. For future reference for all, there are limitless sources of RF interference... atmospheric & weather conditions, solar flares, computers / electronic devices, electric motors, generators, fluorescent lighting just to name a few. Back in the olden days, there weren't as many interfence causing devices in existance, and radios weren't designed with this in mind. Filter circuits weren't nearly as robust as they are these days, so the old radios are a lot more sensitive to the plight. Interference that starts in the early morning and lasts into mid-day is typically due to atmospheric conditions. Being in the two-way radio business, I get calls from customers pretty frequently, complaining about interference in the morning hours. By early afternoon it's gone. Unfortunately, there's nothing that can be done about it. It's just the nature of the beast.
