What kind of antenna tuner do you use? (automatic or manual)
Personally I use the LDG AT-7000 and a G5RV. I have absolutely no problems on any frequency.

Hallo iam using a icom 718 on 28mhz up to 14mhz have a problem of a high swr reading but the antenna is fine then power drop away


Check the feedline to the antenna, and the antenna itself. High SWR means that power is being reflected back from the antenna. A good discussion of SWR may be found here: http://www.hamuniverse.com/wc7iswr.html

If you antenna is designed for 10M and your are trying to transmit 20M on it, there will be a significant mis-match. You may want to look at installing a better broadband antenna, such as an OCFD that will operate better on multiple bands.

How to repair ic-v8 tuner


In the USA, repair and service of a radio frequency transmitter requires a 1st, 2nd, or 3rd class FCC license. The other bad news is the radio probably uses a solid-state chip for tuning, so special tools will be needed to remove and install a new chip. This is best left to a factory repair center.

IC-736 total failure whilst on air, fuse OK, nothing smelt burning etc, not over heated, no voltage surge, SWR was moderate but protected by APC circuit. Totally dead now.


Hi Jack, (No Pun Intended)

As this is such a fine radio, I would take it to the radio doctor for a once over check-up, The technician will find the problem and give you an estimate of cost to repair the fault, Take care of you radio, it's a great unit that should give you many more years of service.

I hope this advice is of help to you.

Cheers,
Peter

This works for the Furuno 1501-Make sure your connections are the same:#1 provide 15V & gnd to tuner(12V works) #2 connect coax between tuner & Xmtr / antenna to tuner #3 set radio to transmit CW carrier @ no more than 10W #4 momentarily short tune to gnd, this will initiate tune process. Watch SWR meter/ listen for tuner to complete, stop 10W carrier & return radio to normal status. I use mine remotely mounted with a 3 wire control cord & a box with a push button momentary switch back at the radio. Connections are 12V & gnd from the power supply to tuner, tune back to control box where the button shorts it to ground to tune.

We bought two Maxon S1 walkie talkies. They do not work. We have tried all the channels (1-8) and several privacy options, but even at ten metres we cannot communicate. Sometimes voice comes through but...


I had the same problem. Take your radio to the professional service. One was ok, but the second has problem with frequency keeping. They shown it on a scanner. The second problem was settings. The output power was set 25 mW, and the band was set wrong to the long range communication. Only professional service can fix it.

While receiving the receiver cuts out momentarily approximately every 10 seconds


This sounds like you have the "Weather Alert" function turned on. With this on, the radio will check for an emergency signal on the weather channels about every 10 seconds.

What's the channel frequencies for a common 22 channel motorola 2 way vhf radio?


Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.

 

With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.

 

If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.

So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats  the case you will need an Icom that will do UHF freqs.
