Question

Hello everybody, just looking for some suggestions.

Here's my issue, there is a UHF repeater a few miles from my house that is active. I have a Yaesu FT-60r handheld and a Yaesu FT-7800 mobile in my truck. I can hit the repeater with my handheld, but not with my mobile. The settings are the exact same in both radios (frequency, tone, etc). My mobile works fine on both VHF and UHF but for some reason the repeater wont pick up my mobile. Does anybody have any ideas what could be wrong. Please ask me any questions for clarification. Thanks!!!

Off the top of my head...doublecheck to ensure that your mobile has repeater-offset engaged [and that it's set for the correct "direction" and frequency difference].

Also, try both rigs with another repeater.

Good luck. http://www.qrz.com/iB_html/non-cgi/emoticons/wink.gif

Yeah, I had checked that. The setup is exactly the same in my mobile and ht. I am completely stumped...

Did you try another UHF repeater, and find that it works fine on the mobile?

You can check that your mobile is putting out a CTCSS tone - dial up a simplex frequency on both the mobile and HT, set the mobile to transmit a CTCSS tone (pick the same one the repeater wants), set the handheld to decode that tone. Talk on the mobile, see if the handheld "hears" the mobile.

If it does NOT, then turn off the CTCSS decode on the handheld and make sure the mobile is transmitting at all! If it is, then your mobile isn't transmitting a tone, or the level of the tone isn't high enough.

If the previous test does work, it is possible that the repeater's CTCSS decoder needs more tone level than your mobile is putting out. If you can hit other UHF repeaters with a tone, then that would seem even likelier.

Are you sure the antenna on the mobile's ok? Correct match? I would check that, too.

I agree with all above.
Check to make sure the mobile has power out,you may have damaged it if your standing wave was to high on the antenna.
