Yaesu ft 900 ham radio pll unlocks from 14.499 mhz to21.499 mhz i tried adjusting trimmer 3 no affect.

I read it could be diodes on bandpass board or it could be voltage regulator problems on the regulator board.

figured out how to solve this, with the radio off, push and hold both up and down scan buttons, while powering the radio on. This will fix the problem.

SOURCE: INTERCHANGE MODULE

I'm gonna go out on a limb here and assume you are talking about the band modules, right? If so it will accept some in the 6m,2m,and a couple of the 70cm bands. The model numbers I know it will accept are as follows: FEX-767-2,-6,-70A and -70B. If your module is one of these they are interchangeable. BTW, all of these modules are presently discontinued I'm sorry to say. Hope this helps!

I cant talk on any frequency over 148.000 anyone know why?!


This is an Amateur (Ham) Radio 2-meter Transceiver. It will only transmit on the 2-meter Amateur band (144-148 MHz) but has expanded receiver coverage from 136-174 MHz which includes Public Service and Commercial 2-Way Radio bands. Please note that an Amateur License is required to operate on the 2-meter Amateur Band.

Any frequency over 148.000 i cant talk on, i can just listen. anyone know why?yaesuft1900r


The Yaesu FT1900R is an Amateur (Ham) Radio 2-meter Transceiver. Although the receiver covers from 136-174 MHz, will only transmit from 144-148 MHz. Please note that you do need an Amateur (Technician Class or above) License to transmit on the 2-meter Amateur Band. You no longer need to pass a Morse Code test to get an Amateur License. You still have to pass a written exam, but that isn't difficult if you are willing to study a bit. Contact your local Ham Radio Club or the American Radio Relay League (A.R.R.L.) for more information.

Ft 2900r yaesu all i see on the screen is B0001 i can't see the frequency


Try powering the unit up while holding the Set/MHz button. I did that and it restored the display (and the rest of the radio's operation) back to normal.

The character codes are test-mode displays that correspond to frequencies (in MHz):

A0001-A0640 - 136.000-143.9875 in 12.5 KHz steps B0001-B0400 - 144.000-147.990 in 10.0 KHz steps
C0001-C2081 - 148.000-174.000 in 12.5 KHz steps

I haven't the foggiest idea why this isn't in the manual somewhere, or at least flipped back to normal by a two-key or three-key reset. 73, k2mct

Any ham radio store should be able to obtain these - if they are still in production / stock by Yaesu. Ham Radio Outlet aka "HRO" has stores nationwide and can ship direct.

I hope this helps!

Sensitivity is a function of the rec rf amp and detector.selectivity is a function of image rejection and oscilator tuning accuracy. You have a good unit, needs aligned properly and troubleshot for bad components in reciever cktry

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.
