Narrowbanding and the Kenwood TK-730H (G)

[JD72305]

Hello Folks,

I am trying to get a 100% answer on a question I have been dealt. We have a base station radio at my department and we are putting into the new budget for new radios to make sure they are all have the narrowband ability. I have seen topics on the TK-730 (G) or the TK-730H but wanted to make sure both are the same. And from what I read the base station IS capable of being narrowbanded. I just want to make sure it is correct. Also the serial number of the radio is 00700448 if that helps.

Also, if it IS NOT capable of being narrowbanded my Chief stated he wanted to see about changing the power supply out. Is that normal to do on radios?

Any help would be greatly appreciated.

Thanks,

Jesse

The TK730G is, we narrow banded a few years ago and I have that radio with remote head (its for sale). Not sure about the H?

In order to be narrow band capable the radio must have a (G) on the end of the model number. Even if it does have a G on the end it will not do many of the new narrow band frequenices due to the limitations in the synthesizer.

My recommendation is to budget for a new radio in the future. Not quite sure why you need to replace the power supply, it should work with a new radio.

IIRC the 730G will not do 2.5KHz steps, so frequencies like 154.8225 cannot be programmed. Most of the pre 2000 subscriber radios from Kenwood and Vertex have firmware limitations on synthesizer steps, they can do the required 2.5KHz deviation but not the newer "splinter" channels. So it depends on what your new narrowband licensed frequencies are.

If they are not splinter channels, the 730G will work just fine. If they are, then you'll need to replace them with newer radios.

The radio in question I assume does not need splinter channels, just make the channels already programmed narrow instead of wide. The "H" and "G" suffixes are unrelated. The "H" only means it is a high power transmit (110 Watts) versus the standard 50ish Watts. The "G" does mean it is narrow band capable. If you have a high power and narrow bandable radio it will have both; TK-730H(G).
