Do you actually have one of these radios that you are trying to operate? Or are you just trying to dig up crap on Youtube and other forums and paste it here?
"the radio makes a picket fence noise or blanks the audio for a split second at regular intervals while the radio updates from the data cable .... that would be on the same cable used for cat control"
I pointed out that blanking/muting the audio is a well-known and acknowledged problem which can be fixed by drawing the audio from the rear panel, and corrected you about which connector it was.
Then you say
the 857 d here is hooked up to the laptop via a usb cable to a plug and play west mountain which is essentially the same thing ... the audio is cut up so badly as to be unrecognizable
So you appear to have ignored the advice on how to work around the problem, in fact you say
i haven't personally verified that myself so can't speak to it,
when this radio is used with cat control usb cable on HRD it constantly chops the audio
And then you bring up two issues unrelated to CAT control - a perceived 60m problem, and a (possibly valid) receive audio quality issue, also that you found and copied/pasted from other forums.
Then you show that you have again ignored the advice and post
it's back in the box and it's goin on ebay or qth ... something as basic as cat controlled vco that hacks up the audio is a big problem and again there are people that claim it works ok for them and again i know people here that are able to duplicate the problem with their 857s
Yeah, I know people too - myself. I personally verified the muting problem exists with MY radio. And the work-around works on MY radio. Did YOU verify the solution with YOUR FT-857d? Why not tell us about YOUR experience? We can search other forums ourselves.
Then you posted a video of a radio that does not have a CAT cable connected, saying the noise shown is a result of the CAT connection... Is this the noise you are experiencing or not?
As a followup, you paste another 3-year-old forum posting, but it again refers to the exact same audio muting problem ... We all agree this problem exists. Have YOU tried the suggested workaround?
Anyway you ignored advice presented in that post as well (ferrites), saying
i dont think putting ferrite beads on anything will solve this problem and i dont use rs 232 convertors at all so there you go
You mentioned earlier the radio "is hooked up to the laptop via a usb cable to a plug and play west mountain".... Well, there is an RS-232 converter in there, turning USB into RxD and TxD for the CAT jack. Even if the CAT data is TTL level (0V/5V) and not RS-232 level (-12V/+12V), it's still square-edged serial data that can induce currents in audio lines and potentially cause RFI.
I PERSONALLY have poked around MY CT-62 and USB converter with a sensitive inductive amplifier probe, trying to find CAT control noise, and right along the serial cable I hear CAT commands as a BRAP BRAP BRAP BRAP BRAP in time with the lights on the USB-to-serial converter... This is pretty normal with RS-232 cables. BUT I don't hear ANYTHING in the audio from the radio itself. No CAT noise present.
So - if you want to sell the radio on eBay, fantastic. Get rid of a product you obviously dislike.
Stirring up this thread with more pasted forum postings and irrelevant Youtube videos, when you ignore the advice offered, isn't doing anyone any good.
Unless the goal has nothing to do with YOUR radio and YOUR operating problems, but is to make a bad name for Yaesu. There seems to be at least one other active poster with the same goal.
Anyway, my FT-857d seems to be working just fine.
Please don't reply with another pasted forum posting "proving" some problem exists. Instead, see if you can make a recording of your own radio's audio issues.

PS. Just an FYI, it's hard to take your un-punctuated, un-capitalized "stream of conciousness" writing style very seriously.
