Charles.  Recommendation.  Ditch the Rx ctcss code, just use the Tx ctcss code.  Next, and I've done this before, drive towards the Repeater until you are certain that you are within 5 of so miles from it with a clear path to the repeater from your location.  Then transmit, identifying yourself (WRQC411) and ask for a radio check.  Assuming the host repeater is programmed the way they are normally programmed, you should hear a "Kerchunk" shortly after your Tx and may even hear a station identification in morse code or other code shortly after your Tx.  Hopefully someone is monitoring the Repeater, hears your request for a radio check, and responds accordingly.  The key to this exercise is to definitively confirm that you're hitting the Repeater.  
Let us know how you make out.

Maggieandmike.  I use a Heavy Duty  LECODO 12V 24V Replacement Cigarette Lighter Male Plug    to power up my 1000G.  It makes it easier for me to transfer between my vehicles because I don't have to hard wire to the vehicle.  That being said, when I was using one of my lesser quality indoor a/c cig plug adapters to power up my 1000G and computer program it, I was having the same problem.  After lots of teeth gnashing and hair pulling I discovered that when I switched to my high quality indoor A/C cig plug adapter, (and was then getting full 12/14V of power,) my problem was over and I was now getting all 30 GMRS channels, etc......
You might want to run a voltage test to be sure that you are getting adequate power to your unit from your vehicle.  This may not be the issue that you're having but it sure was for mine. 
Please let us know.

Thanks wayoverthere.  Appreciate the help and the link.  What you linked is not what I own.  I'm a big fan of BTWR.  They help keeping this part of the industry moving forward.  GMRS seems to be garnering more and more support.  Just noticed in my County, here in Florida that some of the schools in the County school system have GMRS licenses and the frequencies and PL Codes are published.

Uh oh ... having spent nearly 30 years in police cars with low band, high band, UHF, trunking, T-Band, etc. radio antennas right over my head or on the trunk lid may explain my behavior!  ?
