Here is a mod specific to that regulator and radio that you might look into



--
Jeff - NZ2S

Hi Bob,

Thanks for that. "The product must be a multiple of 761" Hi.

?I might try our local Ham Radio dealerships they may sell me one? but it is quite an old radio by todays standards.

But thanks for trying.

73,

Richard G0ILN.

hi?
I have a kenwood TM-255 two metre multi-mode. It will not switch on.? I have traced the fault to a regulator L78LR05B-FA. Farnell can supply them but only in large quantities
RS does not seem to stock the part.

has anyone any idea where I might get such a regulator. I have trawled the internet without any luck.

Charlie,

I was thinking about this, and if you got a speaker that is supposed to have
audio filters but they don't work, maybe you can get a partial refund to make it
worth your while to just have a matching speaker.

Then, make something like this (or buy the kit):


($25.00)

and supply 12V to the speaker, and you'll have a superior audio bandpass filter
(assuming the one your speaker had used passive components and wasn't powered).

I have a Yaesu speaker that matches my 767GX radio and it has the passive audio
filter gutted. I don't know why it was removed but I understand passive filters
don't work nearly as well as an active filter.

Of course, if you don't want to do that, and want to get a refund (if it's not
working or it's damaged), do that and find another one with a working filter.
Just be aware you can end up with something better if you use an active filter.

Can you take off the cover and see if the filters are bypassed?

Hi Bob,
Thank for the quick reply.
So if the speaker I have does not do anything on SSB either, is it fair to say that this unit is suspect/needs work?
I'll focus testing on SSB over the next day or so.
73,
Charlie

I crossposted this to a Kenwood Facebook group but need to cast a wider net for answers. I recently got a Kenwood SP-31 speaker (off eBay) to match with my nice TS-870. I plugged it in and the speaker itself seems fine. I downloaded the manual and read it, then started experimenting with the built in audio filters. But I can hear no evidence that they work, at all. This is disappointing and disturbing but before I ask the seller for a refund, wanted to see if someone here has experience and guidance.

I push the three buttons in all the various possible combinations, but there is essentially no change in the audio. I found _three_ different CW signals close to each other, spread in tone from quite low to medium to high, and tried the filters. No change that I could tell, none were attenuated in the least. Same with SSB, no change in tone or noise or attentuation of nearby signals.

Is this thing broken, or is there something else I need to know, my expectations somewhere off reality? Can it be repaired or improved?

Thanks,
Charlie, WB4FAW
