Re: Wanted: 1500 Hz filter (Noble FILTERS)


 

I don't need one at the moment but I'd be willing to get a new 600 Hz filter for my TR-4cW RIT.? I actually had one in another rig fail and I was fortunate enough to be able to take it apart and fix it using the baking method but these do fail? Are there any other TR-4cW owners who would be willing to do this?

Hello,

He can make almost any filter, however there needs to be enough demand to allow him to acquire materials and put some profit margin into the task!
For one two or three units? It wont happen. It is important for everyone to recognize that at some point, crystal filters are going to fail. Could be now, or years from now. Many times small changes can be compensated for in the alignment process, yet there is a limit. I have had a couple failed filters in my Drake equipment over the years. For filters available through Noble Radio? They are decent! I can't say enough good about them. Consider that there is nowhere else to go if you need one. Installing a "used" filter puts you right back where you started in the quartz oscillator/capacitor aging process.

If enough people need filters, lets sign up, get some quantity demand going, perhaps commit with a 50% deposit, and see if Frank can make something. I would be willing, as I know where this is heading in the next few years.

Thanks,

Joseph

Makes me wonder if Frank could produce a new 48.050-MHz filter for the TR7.?

Frank made up a 1500 Hz filter for me and just received it today.? Works perfectly.? I highly recommend Noble Radio for filters.
