      because I have a HT that has very bad RFI problems but I can use it to test stuff. when the tracker2 stops TX on my mobile I hook up the HT to the tracker2 asap and the PTT lights come on the top of the HT and then after a wile of waiting sometimes it will let go of the HT mode and go back to the mobile mode on it by itself but now it is staying in HT mode and NO the HT jumper isnt installed at all. I'm able to change the commands on my tracker2 via my nuvi 350 duh. I can hear the sound coming from the HT with using another radio I don’t need a scope to know this. but I'm also not much into trying to fix stuff I don’t know much about, when you do this you just mess it up even wost. I have been able to get a opentracker and a TT4 working so I do know how to do some stuff. I guess I could always find the 2.2k resistor you talk about and take it out of there sience I don’t need HT use at all,sience this is the only problem I'm having is it wont stay out of HT mode but again why do this and risk really messing up the unit. I was thinking just maybe I was doing something wroung until I seen this past email from this person and I took the unit out of the box and did seen a lot of solder points just about touching each other and I can see how they would touch each other very easy. but I'm noting going to get upset or try to start any fights on group. the easy fix is have someone that knows what they are doing take a look at it, I have already made plans to go home tuesday to get the box and packing and get it mailed out.

      Okay, I'm baffled... how do you know that the unit is in HT mode?

      The easy way to tell would be to look at the jumper and see that it is
      across the HT pins.

      The HT jumper couples the PTT out to the audio out line via a 2.2K
      resistor. Have you been able to confirm that you are seeing the PTT
      assertion on the audio line by monitoring the audio line with a meter
      or scope?

      To do what? You are not able to change the HT setting via the command
      console, which is what I am thinking that you are talking about.

      You can spend a lot of time trying to fix a problem that doesn't
      exist. I'm not convinced that you have a problem with the HT setting.
      The information you have provided so far is insufficient to be able to
      confirm or deny the suggested issue.
