SOURCE: OLDER ICOM RADIO ICBP5 AND A REGENCY U156B

Hi, The Icom radio models start with IC followed by numbers and then letter(s). The BP5 is the model of the battery pack. Pls post back. I'm not familiar with Regency U156B. However, there is a Regency RU156 which is a 16 channel UHF 25watt mobile radio which could either be crystal controlled or PLL diode matrix. Regency was reported sold to the BK Relm Company, which no longer supports older Regency Radio Equipment. There are a few sites on the Internet where you can get hold of a user's manual (some for a fee) like http://www.bearcat1.com/manuals.htm. Hope this be of some help/idea. Post back how thin gs turned up, the Icom model or should you need additional information. Good luck and kind regards.

Icom ic-756 pro 3.dead spots in TX and RX ,maybe pll ?

If the dial actually shows the 40M frequency, then the likely hood of the PLL not functioning is slim. My guess is that the band pass filter for 40M has a bad relay or steering diode in it. This happens more often than not and is a rather inexpensive repair. I have the same problem in my IC-706, except 20M is affected.

Tenma 72-2580 scope I want to hook up the scope to monitor the rf wave form and audio wave form on my ham radio how do I do this

I suspect a small antenna could pick up the transmitter level. And the audio I suspect is from the speaker. That is a level the scope could handle. Solder a couple wires to the speaker or hook the scope leads to the speaker output if it is an external speaker rig. I am also a Ham and have a O scope. 2 Channel 30 MHz Oscilloscope with 8 Color TFT Display

How come my icom 756 pro did not transmitting on 8000 frequency

You have to modify this radio to operate outside of the HAM bands. You will likely find the modification at www.mods.dk. This is a pretty common and easy modification for HAM radios. Your performance may not be as good as in the HAM bands.

You do this MOD at your own risk. If you are not licensed for operation on ANY frequency or band, you are not legally allowed to transmit. Heavy fines may be levied against you.

I have a icom ic2300h transceiver. I can listen to ppl talk but if I key the mike to answer the screens says off. Why would that be?

The only time I have seen this response, is when the radio does not have the MARS/CAP modification. Which means you are trying to transmit outside of the ham radio 2 meter band.

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.

Not finding what you are looking for?
