You may have to tighten the squelch setting but also the "ambulance channel" could have delayed squelch to allow units to respond.

Testimonial: "Thanks Tom. The signal that opens the channel is very weak DTMF but the signal that holds the channel open is in fact a full strength noise. To squelch this signal would mean no other channels would open the receiver."

? 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.

I can't turn off the squelch on my Radio Shack Digital Trunking scanner.


On all channels, or on one channel ? Some channels are "birdie" channels, check your user manual. Others are problem channels receiving false signals from computers, monitors, receivers, internet equipment, FAX machines, etc. If your in conventional mode, if in Digital mode the squelch is set by the processor, and I don't believe the squelch has any effect in that mode.

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.

Radio not receiving on any channel


Hi Mike,

The manual for this radio (in Adobe .pdf format) is available for download directly from Icom America, free of charges.

Since the "AquaQuake" function works and you do hear static when the squelch is off, that is sufficient to let us know that the voice coil of the speaker is functional and should produce sounds with the right signal applied.

The first thing to determine is if you're close enough to another operating transmitter for the radio to receive a signal. One of the 10 weather channels the radio is capable of tuning should be close enough produce some intelligible audio from the speaker - assuming the squelch setting isn't set too high.

If a WX channel works, then you'll need to see if there's a VHF Marine band transmitter operating nearby. You might need to set another Marine band radio receiver up to verify that there is indeed a signal present on the particular Marine band channel that you're monitoring. A list of frequencies is published on pg 27 (of the manual linked above) in case you need to convert between channel and frequency to tune on a non-channelized radio.

Outside of that, there's little the end user can do without specialized test equipment, schematics and of course, training. Many shops will be happy to provide an estimate for repair when provided with a small bench diagnostic fee. This fee is usually applied towards an authorized repair by most reputable repair shops.

I hope this helps & good luck!

Help!i have just purchased an i-com R5 the manual keeps referring to the VFO,i know what it means but how do i know when the scanner is actually in the vfo mode??? deranged of swansea!!!


VFO stands for Variable Frequency Oscillator. This is the function that allows you to enter frequencies. It just means you are not in memory channel mode. You can get more info at the factory web sight and download the instruction manual for free.

I have been using the IC-R5 for a few years now with no problems except when using it during the summer. If the weather is hot, after being switched on for a period of time the scanner just starts to bleap...


The occilator that "locks" the VFO (like a clock signal) is gong out of range. The higher temps are affecting the temprature controlled occilator. I would send the unit to ICOM for repair.

Getting started with the ICOM IC_R5


First set the squelch (gets rid of the hissing noise and allows the radio to scan)
to do this....

On the side are 2 buttons, the bottom one is monitor.
press and hold then look at the display,
turn the top dial until "AUTO" appears,

The squelch should now keep the radio quiet.

Now the tuning step..
You need to set this because if your radio was on 450.000 and you wanted to listen to 450.012.5 you would miss it if your radio was making 000.025 "steps". IE you would need 12.5 steps. This is the most common step used by ambulance etc in the UK, you will need to check local band plans.
Stick with 12.5 and you should get most stuff on VHF / UHF.
For airband 12.5 will get most stuff, but some is now changing to 8.33.
For HF (below) 136 Mhz I'd use 5

To set the step....

On the front there are 4 big buttons.
press [V/M.S.MW.SKIP] to select VFO mode,
then press [BAND.LOCK] to select the band you want to listen to,
then press [TS.SET] to enter the step
turn the dial to select your step (stick with 12.5 for now)
press [TS.SET] to exit back to VFO mode



To scan...

First set the scan type...
On the front there are 4 big buttons.
Press and hold the one that says [MODE.SCAN] for 2 seconds and look at the display,
turn the top dial until the screen reads ALL,
press [MODE.SCAN] again and the radio should start to scan with the 12.5 steps you set earlier.
If you want to change scan direction, just turn the top dial.
If you want to stop the scan, just press [MODE.SCAN].

When you hear something interesting, make a note of the frequency on the display.

To set memories (store frequencies).....

On the front there are 4 big buttons.
press [V/M.S.MW.SKIP] to select VFO mode,

to get close to the frequency you made a note of, press [BAND.LOCK]
Then set the actual frequency with the top dial,
press and hold [V/M.S.MW.SKIP] for 2 seconds to select memory write mode (1 short and 1 long beep)
turn the top dial to select which channel you would like to overwrite. Start with 01.
press [V/M.S.MW.SKIP] for 2 seconds. ( 3 beeps )

Thats it!

Any more problems just post on here and either me or someone else will help.
