DUALWATCH/  Description Dualwatch monitors Channel on another channel; Tri-watch monitors Channel 16 call channel while receiving another is convenient for monitoring operating on another channel. DUALWATCH/TRI-WATCH SIMULATION Call channel Dualwatch Tri-watch • If a signal is received on Channel 16, Dualwatch/Tri-watch pauses on Channel 16 until the signal disappears. • If a signal is received on the call channel during Tri-watch, Tri-watch becomes Dualwatch until the signal disappears. • To transmit on the selected channel during Dualwatch/Triwatch, push and hold [PTT] .  Operation q Select Dualwatch or Tri-watch in Set mode. (p. w Rotate [CHANNEL] to select the desired operating e Push [DIAL•DUAL/GRP] for 1 sec. to start Dualwatch or Tri-watch. •"DDDU UUA AAL LL 1 116 66" appears during Dualwatch; " T TTR RRI II 1 116 66" appears during Tri-watch. • A beep tone sounds when a signal is received on r To cancel Dualwatch/Tri-watch, push [DIAL• DUAL/GRP] again.

turn the squelch down? the RF gain down too do you have an attenuator turned on ?

There is normally an electrolytic capacitor on the back of the display that regulates voltage for brightness. Sometimes thy are easy to replace. Or give it to a radio engineer, or return it to Icom for repair. They would likely just replace the display module and board. Someone else reports low contrast. https://forums.radioreference.com/threads/ic-a24-screen-contrast.321716/ https://www.google.com/search?q=ICOM+IC-a24+blank+display ..

It can be a few things but first try resetting your CPU, while your transceiver is off, hold down the UP & DOWN buttons simultaneously then turn the transceiver back on, now it should be reset to the factory default settings

Send it in for repair. It is broken https://www.google.com/search?q=Icom+ic-210e

The Fix Programming via CS-R6 with Windows 10 made the problem. Scanning was very slow. The CS-R6 program through Windows 10 made problems with the scanning speed - it became very slow, one frequency in 2 seconds instead of 100 frequencies in one second. Through programming CS-R6 on Windows 7, the scanning speed returned to the corresponding one in the ICOM instructions - 100 frequencies per second

Hi, please move the radio away from it's current position to attempt to find alternative position where it's frequency will be transmitted clearly as intended. Also, please keep away from any microwaves or speakers so as not to cause any interference. Thank you.

There are a few possible reasons why your radio might not be transmitting in CW mode. One possibility is that the keyer chip has gone bad. Another possibility is that there is a problem with the power supply. If you have a multimeter, you can check the voltages to see if they are within specification. Finally, it's also possible that there is something wrong with the antenna connection. Make sure that everything is securely connected and that there are no loose wires. I hope this helps!

Hi om sounds like you may have a break or something making that ant go haywire, have you checked all the line to see if there may be connection problem.another thing could you try the ant direct with a matcher inbetween to eliminate the auto tuner from circiut. This would narrow the fault down, have fun

The RX light should light up when receiving a signal. It may be your squelch setting is too high. Push the VOL knob until it enters the squelch setting, then set the squelch so it just cancels noise. If still not working you could have a wire broken in connector from headset that plugs into the radio.

I have an icom 91 and still haven't figured it out. It is easier to use an app and computer and more intuitive.

You need to be a very good technical person with electronics to work on these. The issue is most likely a PLL board issue. You need to be able to troubleshoot to the component level. The service manual appears to be https://www.manualslib.com/manual/738448/Icom-Ic-706mkiig.html
