Gentlemen, About a month ago there was several posts about which was the better trackers. Several people voiced their findings after comparing several common types.
If I remember correctly most people were more than happy with the Tracker 2. However few people voiced an opinion as to why one was better than the other. I think the only comment was that a sound card is the best because there is more digital bits available. Someone said the Tracker 2 was far better than the T2-135. The reason for this email :- I am about to attempt to make several APRS repeaters by using Ex commercial two way radios and a Tracker 2. However the TNC has to fit inside the radio. This requires using the T2-135. I will have to design a PCB with the SMD T2-135 mounted on it in such a way that it fits in spare space within the Radio. Comparing the published circuits of both the Tracker 2 and the T2-135 the only difference that can effect the sensitivity of the TNC is the Tracker 2 has an input filter/limiter that is not in the T2-135. I was hoping that, if I add the filter that is the same as the Tracker2, this would then make them equal. Is my assumption correct? Has anyone else used the T2-135 with other radio types other than the Alinco? If so did you encounter any problems and how did you overcome them? Thanks David David G.
