Harris P7300

[N1XDS]

I have a Harris P7300 portable radio with limited keypad and the volume/channel knob are loose but channel knob is looser than the volume knob and was wondering what is the hex/torx screw number for the screw that is behind where the antenna goes so I can tighten up both knobs. Thank you

t5 works on mine, but its a system, no idea if that makes a difference

Thank you for your reply How do I go about to tighten them up?

Is it loose as wobbles? If so the set screw might need tightening. Pull the knob off and there is a set screw there(at least for the channel selector, to tired to get a good grip on the volume knob to get it off ). If that does not help for the channel selector it might be the mechanical part itself. The manual states 1.27mm hex but I was able to unscrew mine with the same t5. It does not state anything that I have found yet for the volume button. Apparently at some point the 7300's did not come with the mechanical stop installed and had to be done when received. Imagine doing that for 1k+ radios.

edit* I found a ebay listing with a missing volume knob(lol). It had a few images and just happen to have a shot of the backside which is where the set screw was shown as, assuming the volume is currently in off position. It looks like the same size as the one for the channel selector.

That helped! I got both of them tighten now. I may order a new volume and channel knob to replace the old ones. Yeah, Loose as in wobbles especially the channel knob if I push slowly to the left the channel knob moves I am not sure if its suppose to do that but I made sure I tighten them both. I stopped after four turns but I can still turn the set screw on the channel knob but I am not sure if I need to keep tighten them up or its suppose to be tighten but some what loose to turn the knob.
