    Harlan,

    I entered "Overland, KS" in the QRZ database search box and came up with over 450 "hits" and several pages listing hams in Overland, KS.. With all due respect, you are way over your head trying to operate your 820.. Before you damage it - if you haven't already - contact some of the following hams in your area and see if you can get someone to personally assist you..

    I cannot imagine a problem that would cause the bias to change as you switch bands, let alone QSY within a band.

    I second the above advice, you really need to get a experienced operator to help you.

    I also agree. Numerous hams, including myself, have suggested he seek help from local experienced hams yet it appears he has not done that. He continues to create new post containing statements that more often than not, make no sense!

    KLH,

    I have used the Kenwood TS-599 twins back in the day. The TS-820 uses a pair of 6146's and should have IP current of about 60mA for most of the bands; however, 10M can be lower. While I'm not sure of your setup, you should be turning the rig in cw mode with some sort of dummy load. The ALC is not a good indicator of xmit activity. If you have a manual, follow the instructions for tuning up the rig using CW mode going from low power to full power into the load. Once that's done, switch over to USB and then check for some ALC meter movement. If you don't have the 820 manual, you can find one on the web somewhere. The TS-820 is a good rig as are all the rigs of that age and with some due care and attention it will serve you for years to come.

    Ken

    Absolutly not!

    The frequency has ZERO to do with the bias.




    Again wrong, the ALC is the BEST indicator of transmitter drive (or overdrive)

    Possible excessive carrier on SSB..
    Our friend needs an Elmer in his aria to sit down with him and walk him through the operating procedure and give the radio the once over.

    That post was on the first half of my first cup of coffee even.

    It amazes me that it's coherent.
    The TS-820 is still fresh in my mind having overhauled my 820 last year. I have to dig into it again. The WWV position quit working, I think it's just PLL alignment.
    I have a new project on it's way so I am not eager to dig into 820 just yet. I picked up a project R-599 and I am waiting with baited breath for it's arrival.
    More on that later......

    Rege,

    I used a friend's TS-820 too many years ago. It did suffer on 10M as I recall. But, as you say, frequency has nothing to do with bias. As for ALC, I don't and wouldn't recommend it to indicate xmtr drive.

    Nevertheless, my advise remains: get and follow the manual. And, as others have mentioned, contact another local ham.

    Ken ... I have no clue why this guy will not look for help locally. He continues to come here with haphazard statements that make little to no sense ... and expects immediate correct answers, which we cannot give, given his haphazard statements.

    Find someone locally ... and quit wasting your and our time. It has become quite apparent, you have no clue what you are doing nor why. You do not understnd the radio .. period.

    That becme quite apparent when you said the 6146's provided the voltage.

    Again, find someone locally.

    Quite true, frequency of operation has zero to do with bias. Never has ...never will.

    KLH we suggest that YOU read the advice given ... find someone locally unless your main desire is to ruin the radio. You keep posting the same stuff, get help and learn ....

    Has nothing to do with flying ... medical or otherwise.

    Get help locally and quit wasting YOUR time.

    As 3Y said, you are NOT listening.

    OK, You have a dummy load; replaced the three tubes and all light up;
    Page 18 has the driver set with the meter switch to ALC and the mode set to TUN[E] and peaking the DRIVER to max meter reading. When you hit the "send" to transmit, do you get a maximum meter reading at this time? Have you tried/turned the CAR control to get a meter reading other than zero?

    Next, on the bottom of pg 18, you've switch the meter to IP and then hit the "send" switch again [a quick on, look see, then back to off] with no current reading. Is that right?

    Page 19 shows all the switch and control knob positions on the two tables.
    Are you saying the meter readings for IP are zero when you hit the 'send' switch in the CW mode position and you are following table 2 on page 19?

    You might want to do this offline, my email url is kenharrigan at verizon dot net.

    He's doing the same exact thing on eham.net, posting incomplete sentences and statements and jumping from one radio to another without any rhyme or reason.

    Folks on eham are also telling him the same thing he was told here on the ZED, get help from a local ham. But, so far it appears he is ignoring these suggestions as well.

    More likely a bad WWV band XTAL gone bad, since that rig has NO PLL !!!:eek:

    Wrong.

    Look up Kenwood P/N X60-1010-00 in either the TS-820 Service or Owner's manual and tell me what you see. ;)

    That said: T1 (on the VCO) unit probably needs a slight tweaking. It's the tuning adjustment for the WWV/JJY oscillator.
