Check the voltage at the radio as stated above, but set your meter to read the ALC and see if that value changes and also the SWR. In the radio the ALC voltage controls the power of the output and

Phil, K4PO? Thanks for the suggestion, I haven't checked voltage but will monitor it as I transmit and see if I can learn anything.? In the meantime, I will check all connections and fuse.? I

Willard, The first thing that comes to mind is the 12VDC power reaching the radio is falling off as you transmit.? This is often caused by power line fuse corrosion or other poor connection.? The

Is your cooling fan running ok? -- Leonard K. Pennock (AD7AS)

I am primarily a CW op and use the FT-857 as my base station.? Lately while using the 857, the power will immediately reduce down to close to zero but I can still hear myself keying..? There have

Hi, Be careful, if yu have this problem on FT857, the well-known IF filters problems seems to hear like static crashes. 73 Laurent F1NFY

Best idea! One RX on desired frequency and the other on near-by frequency with no signal - just static crashes! One antenna. Simply mix the audio 180 degrees out of phase. Should be "easy" with SDR

Interesting "what if" question. It would probably work detecting "digital signal" . Say using CW and detecting start - from "off" to "on"? and then "stop" from "on" to "off" , and regenerating (

Thank you Mick. Thats a new tip for me 73s GD Unni VU2TE wrote:

Thanks Dr Vaclav for the info will checkit. 73s GD [email protected]> wrote:

That's gonna be hard to do if its not powering up or takes a long time to do so. Mick SA4MDN

Hold bands Up/Down buttons while Powering on will start a relay cleaning session

I think there is a way to "exercise" the head power relay. Check the manual for details. 73 AA7EJ? Vaclav

It came on automatically. This problem was earlier also. It will not get switched on sometime. so keep the power supply on then after some time it functions as normal. Use to take short time for this.

There is a fuse mentioned in the service manual F 1001 Maybe worth a look with a multimeter

Dear Elwyn Thanks for the response mail. Nothing was disturbed on the set. Just switched off the rig the previous day and when I switched on nothing happened. opened the rig cover and checked the

So you've got the head plugged in properly, and the data cable is in the right place? You've not left a programming lead plugged in have you? And you've got 12v power going to the radio? Checked all

Dear all My 857D not getting switched on checked voltage up to PCB and tried after removing the brown jumper but no luck looks for help to locate the problem 73 s and regards VU2TE UNNI

The drift might have been some slight tension or dirt in the tuning knob tension assembly pulling the knob slightly. My radio mobile will change frequency with vibration of the car if the tension

UPDATE: The drift seems to have been a fluke. I've been monitoring several times, two hours at a time and the radio is rock solid. Even off overnight and watching for the first two hours after turn on
