? new bp 200 replacment for bp 199 will not operate my ic t8e radio

The IC-T8E is the Icom VHF / UHF Amateur (or "Ham") transceiver capable of wide-band AM & FM receive and 6 meter (50Mhz - 54Mhz) , 2 (144Mhz - 148Mhz) meter and 70 centimeter (430Mhz - 450Mhz) FM only transmit - when appropriately licensed by your country's communications authority.

RigPix Database Icom IC T8E

Any FM transmitter operating in those frequency ranges will be received and played thru the speaker - unless they are encoded with a squelch decode sub-audible tone or digitally encoded squelch control that does not match the one set to the IC-T8E. Program the squelch to be open or to match that of the transmitter so that the radio will play only when that particular transmitter is transmitting.

An FM transmitter operating in APCO25, DSTAR, etc. will not be decoded as these are digital signals that the ICT82 is not capable of decoding.

I was unable to locate any "BP200" radio you mentioned, so I can't comment on their capabilities or if they have an incompatibility in encoding, frequency, etc.

Can you change the squelch setting on an ICOM F61V

The squelch setting can only be changed with dealer programming software. A Manual for this radio is available from

Icom m36 will not receive. Speaker makes noise with squelch all the way up but just won't receive anything including weather.

You may have the CTCSS tone squelch enabled so unless a station you're listening to is encoding CTCSS tones, you won't hear the traffic you're expecting.

I recently bought a new icom ic-41s from my paragliding instructor. When I bought it, he set it up for tone squelch as that was what we were using. Now I want to turn it off however no matter how many...

  1. Select the channel you want to adjust the CTCSS/DTCS squelch on.
  2. Press and hold the "Set Mode" button on the top of the radio for 2 seconds to enter set mode.
  3. Push the top button again several times until "C" appears.
  4. Push "Scan/Tag" to toggle the CTCSS tone frequency/DTCS code setting modes.
  5. Push "CH Up" or "CH Down" to set the desired CTCSS/DTCS code or remove the codes by rotating it to "0" or "OFF."
  6. When the tones are set as you wish press and hold the "set" button at the top of the radio again for 2 seconds to exit.
  7. Done.
Regards, Tony
