Hi Ronald,

Could the problem be related by having the mike to close to your mouth? This is the most common cause of over-modulation/ distortion from the transmission end.

If you have the mike 3-6 inches from the mouth and speak in an even non loud tone, that would help sort that out. If this is not the source of the over modulation/distortion, then you may have a transmitter issue, which would require the unit to be serviced by a qualified radio technician or ham radio operator, if you know one willing to look at it for you.

I hope that this has helped you.

Cheers,
Peter

SOURCE: my transceiver yaesu ft-one can't received/monitor and transmit

Thanks 4 your advice.
I left the radio w/o any batteries (the only battery is back up memory battery) in that time, and when I try the radio I used new batteries. The power supply for the radio is build in (uses 30 amperes switching power supply) and I have checked that the power supply is in a good condition. I suspect that PLL unit is not working so can't oscillation to generate frequencies.
The problem with sending the unit to the factory to be serviced is not worth (cost > benefit/ radio value).
Do you have another idea to help me? Please.. Thanks

SOURCE: PPT works in the lower bands (under 148 Mhz) but not 156 range

Your radio has not been modified to transmit outside of the amateur bands.

Radio power`s on but no transmit or receive on ssb however it will transmit with full power on fm


If your receiver was operating previously but now the SSB option is not working, very likely the sideband detector has failed. I'm not directly familiar with your Yaesu unit but, in most Yaesu transceivers, the SSB chip and control circuit (including diodes) is identified in print on the main board.

My Yaesu Ft-857 transmits ok on 2 meter. But the receive only work sometime?


Sounds like a bad receiver in the radio.
Have you checked the VSWR of you antenna system?
Did it ever work with the current setup?
If so has anything changed with the programming of the radio or the antenna system?
Does 70cm work OK?
Are you sure menu item 080 is set to "SQL" and not "RF-GAIN"?
Are you sure the receiver is not programmed for tone squelch?
Either of those settings could cause receive problems if not used properly.

How to turn beep off when transmitting


all the beep is for is so people can tell when you are done transmitting. There should be a push knob or button or just a plain old knob that has R.B. printed next to it . Turn it off.

How do i get expanded freqs on my ft1802 yaesu tranceiver


The FT-1802 is a 50 watt 2 meter FM transceiver. It can transmit anywhere between 144 - 148 Mhz (the FM portion) of the 2 meter ham band. It can receive anywhere between 136 - 174 Mhz without any modifications. There is a modification to enable transmit "out of band" below:

http://www.ham.dmz.ro/yaesu/ft-1802-extended-transmit-modification.php

There are few details about the results of this mod - typically these provide for transmitting on frequencies outside (above, below or both) of the 2 meter ham band. Transmitting outside of the ham band without a proper license for the frequencies in the U.S. is a violation of FCC rules.

I have a FT-8900 and want to be able to open the AM side so I can use it on frequency 26.805 is there anyway it can be done


The Yaesu FT-8900 is a quad band FM transceiver only. It can not be modified to receive or transmit AM, SSB, RTTY or CW. It works on all or portions of 70 centimeter, 2 meter, 6 meter and 10 meter bands. The 26.805 Mhz frequency is 11 meters, so it is out of range of the 10 meter band in the radio, it is close. Even if able expand the transceiver, the AM / SSB mode commonly found in this band makes it impossible to use. Further, the radio is not FCC Type Accepted for use in this band.
