Thanks Ronald,? That's why I was trying to be as detailed as possible. I noted in the manual the reported effect on the S meter when turning down the gain, so I probably should have reported that

A couple clues you mentioned. S meter at S9+++ might indicate that the RF Gain is turned down. RF gain shares the squelch knob. You also might try downloading the ARCP 480 remote control program

Yours looks to be an 857D like mine. Emailing customer support will get you full confirmation. Yaesu still supports these. Juan

Thanks Juan, I don't see an actual DIP (as in an IC) socket.? I do see that the module along the left chassis wall is plugged in to the main board though.? Guessing this is an 857D from the factory

If the circuit board has a DIP socket on the top of the board, lower left as seen from the front, it is an 857. If it has a chip on the socket it's been upgraded to an 857D. If it has no socket, it

Apologies to the mods.? I overlooked that the new guy is moderated. Some additional details since I sent the first message.? I have opened the cover of the control head.? All of the buttons seem

Apologies if this comes through twice. Originally sent by email and it still hasn't appeared after 3 hours, so trying the web interface. Hi All, - I've read through all the buttons related questions

Hi All, - I've read through all the buttons related questions I can find. My issue doesn't quite match any of them - No, it's not locked - Yes, I have cleaned the control head contacts - Yes, I have

Remove the control head again and, with a Q-tip and/or cloth saturated with Deoxit, clean any and all contacts you can get to. That the buttons "worked for a minute" sounds to me like a possible

Try a different cable. If the problem persists your might have a bad control head. Replacements are readily available. [email protected]> wrote:

Thanks k1prc. I did as you advised. Removed the cover, blew out the dust with a can of air, inspected what I could see and reassembled. It worked..for a minute. But, it didn't last and went back to my

Remove the control head from the chassis, disconnect the head cable and check for dust or other debris/damage. Reconnect and ensure proper seating. [email protected]> wrote:

I found a filter I think I can use. Specs are 455 khz USB, 250 hz BW @ 2dB down, 3.2 khz BW @ 50 dB down, 9dB insertion loss. I bought the last one the seller had. Do these specs make sense for a CW

Ok. I will see if I can find one of those two. So far I have only found the YF-122CN's in Japan at pretty high prices, and nine of the individual filters. I tried Collins, they said no stock. But that

You could operate with a 200Hz width, just like a 300Hz filter. These are handy when you are trying to isolate one station right next to another. Filters do present some insertion loss, so you would

My pleasure. I went from a Kenwood TS-520SE to a Drake TR-4C to the FT-897D. A hybrid to tubed to a computer. I love the 857D/897D but was surprised at the learning curve. I learned all of this from
