Hello, Since they are sending my dead unit back, I will try and diagnose the sequence path of turn on.? I tried to manually key the main relay and that worked, but still no turn on.? So there has to

Well finally sent the radio in for repair and got the estimate $871 plus shipping.? NO WAY.? They don't trouble shoot to the component level just replace boards.? I would like to know the sequence

In case you need a manual see https://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&encProdID=8CBB7C4BDBAF40129AD4253A4987523C Phil / K4PO

In addition to the capital above the frequency, there will be a triangle/arrow icon next to the IPO option (bottom row of the display).? Note that the IPO option is in the Multi Function "m" (MFm)

You get a capital i on the display it only works on hf .. Pete wrote:

How do you know if IPO is on? Guy/N4DEL

Thanks Larry, you just helped solve my high noise floor on my 857D as well. 73's, William, N5WOI.

Check out Rob Sherwood's presentation on RX imod and roofing filters . we lost a lot of selectivity when they included a 1st IF filter wide enough for 10m FM.

Do you have the IPO turned on?? If it's turned off the receiver preamp is turned on, and that will boost noise floor.? The same holds true for the FT-2000 and FT-950. 73, K0LEJ

My 857D has a big noice level on f. ex. 80 mts. Compared to my ft-2000 and ft-950 is is a lot. To compare like this is not fair, but I hope that there is a way to get rid of lot of that noice. When

remember ssb and am oower es measured differently

Another thing to remeber is that for 100W OP, the resting carrier (no modulation) the OP is 25W.? I found that it sounded better at 15-20W, though...

Thanks Phil I will leave it as it is with HRD. Till now no damage done to the rig. Further I dont want to get in trouble Thank You and 73s VU2TE Unni

For a time CHIRP was writing to the same 857D eprom area that eventually rendered some radios to brick status.? Believe CHIRP developer removed some features to avoid that result.? Phil / K4PO

Which features did HRD implement with a slider? I know things like the noise blanker cause EEPROM writes so dragging a slider would definitely hammer specific cells in the memory chip. Thanks, Joe

Dear Eric That was the same reason told by HRD people. Any way will wait and see 73s and GD GL Unni VU2TE

Update:? I live close to the Yaesu facility in Cerritos CA.? I met with Yaesu techs Tim and Peter and went over this with them.? They are as baffled as we are and have taken on the task of

Hi Unni, I think that this may have been removed because it can cause a problem after some time of usage. Possibly after a year or more, depending on how much you use it. I believe that the problem is

I have the exact same issue with mine. Been doing that for a long time. Doing a master reset does not help. I also noticed that a few other menu options will change slightly. For example, FM mic gain

Thanks, can you elaborate on why you think it might be the keying line? John K6JMQ
