Tidradio TD-H3 weird behavior

[WSIQ356]

I am very new to GMRS, the reason I got into this is because I like camping and it seems like a lot of campers use radios. I got my license and bought 2 hand held units. I have 2 Tidradio TD-H3 units, I am trying to program a local repeater (Pike Peak) I have the frequency 462.67500, and the tone 141.3 hz, I have also added the offset.    I did this before and when I pressed the PTT button I got a morse code back from the repeater.  After messing around with my radios for a while I decided to reset the radio and add more repeaters for a trip I am planning to take over the Olympic forest.  I am using ODMASTER on both my phone and computer to program the radio units, I tried CHIRP but my computer does not have a USB A port, and my adapters dont seem to work with CHIRP. 

Now, I dont get a beep back from the repeater, could be that its down,  I have actually driven to be about a quarter of a mile from the repeater and I believe its in line of sight and still get nothing back.  I did note that when I press the PTT button the frequency changes to 467.675 as it should.  I am using the TD-771 antenna on my radio (not sure that is the correct one to use).  And if I have both radios on hand, I can see that sometimes when pressing the PTT on radio 1,  the other (radio 2) receives signal, but nothing comes through in form of sound, it just springs into life and shows the little green arrow that indicates its receiving signal.  And also, regardless of what is in the other BAND on radio 2 (receiving radio), can be a GRMS simplex channel, static comes through after a couple of seconds of holding the PTT button on radio 1.  Can this just be interference? Am I doing something wrong? can it be that the repeater is just down? am I missing something in the programing? (I have tried programing with ODMASTER and on the device itself and get the same results).

Both radios have the TD 771 antenna that came with them installed, I can switch to the smaller antenna (UHF:400-470 MHz) that also came with the radios but I get the same result.  I have tested the radios by using simplex channels and they work up to 3-4 miles away.  And I can hear people on other simplex channels.

A repeater may not always give you the ID back.  It's usually on a timer (15 min) and will only ID after that time has expired.  If you are receiving a signal back pressing the PTT you are hitting the repeater.

Have you tried shouting your call-sign on the repeater and seeing if anyone else can hear you? With both radios side by side like you describe, you're de-sensing the receiving radio while you're transmitting to the repeater so it won't 'hear' much of anything until you come off the button. Try talking, see if you get anywhere. Or have someone hold the other radio some distance away and see if they can hear you.
