The Radio Information Board

I am not sure I understand your question. You need to use the specific model type for your radio. You can't change the radio by attemtping to program it as a different model. You MUST have a stable computer and programming cable connection before you attempt to program the radio or you will "br...

The problem is that DOS software depends on dedicated access to the com port and no other processes running in the background that can cause any interruption of the data flow to the com port during programming. Once you have windows running or have device drivers involved for a USB port, etc there i...

I checked the CAP website listing of NTIA compliant radios and it says the 730G is narrow band compliant only for continued use if it was already in service on 1/2006 AND it has the 2.0PPM stability option. In addition to the VCO lock question, the radios TX and RX performance rolls off as you move ...

If the VCO is out of lock, it could indicate that either an out of range frequency has been programmed or the VCO is defective. In some cases a VCO can be returned to slightly shift the frequency range. If you have to ask what a VCO is, I doubt you have the knowledge and test equipment to attempt to...

The MARS/CAP modification is pure BS. Ham radios are not allowed for MARS or CAP use because they do not meet current technical standards for these services. Ham radios are not designed for Public Safety use. They do not meet technical standards. The maunfacturer's specs generally say guaranteed onl...

The part # for the current version of the manual is:

B51-8720-10 S/M (REVISED) TK-2170 K K2 K3 M $18.00

KPG56d Ver 3.20 (DOS) was released in 2001 so anything earlier than 3 is ancient. As I recall, there were problems with V2 and I don't recall ever seeing a V1.

Ver 4.x is Windows.

The ICOM website says the USA version IS capable of 2.5KHz steps.

It sounds like synthesizer/interconnect board trouble.

Some possibilities are:
Bad EEprom
Bad 5V regulators
Bad microprocessor
Bad microprocessor crystal

Those frequencies are only divisible by 2.5 so any older radio that can only do steps of 5 or 6.25 won't work. This is true of all radio maunfacturers. Before the FCC adopted these non-standard frequencies, there was no reason to have a radio that could do 2.5KHz steps. Generally, unless the radio m...

Joe, I know nothing and less every day. But in response to a question I asked last month about Kenwood handhelds on here I was told "The G indicates its Narrow band capable." So the TK-272G should be OK for you. Once again - "narrow band capable" on VHF does NOT mean the radio h...

Hello folks, I have the same problem. I have a TK-730H(G) which is supposed to be the narrowband compliant version(unless someone can explain why it isnt)! See my previous reply. The 730H(G) is "narrow band compliant" for the international/government channels which are 12.5/6.25KHz spacin...

The "narrow band" version does international/government 12.5/6.25KHz channels but it is NOT capable of the FCC 7.5KHz bandplan.

The idea of the reverse protection diode is that if the radio is connected backwards, the diode will conduct and blow the fuse. The only time the diode will sustain damage is if somebody reverse-connects the radio with no fuse in the main power leads (and you can usually tell if this has happened b...

There's no way to make the radio send two subaudible tones. Maybe you could convince the other department to program in a channel with carrier squelch receive. That's about the only way to accomplish it. If everybody on the mutual aid scene switches their units to CSQ receive there should be no pro...
