• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

TRI Harris PRC-152 - confusion over radio pin out, battery pin out and TRI charger pin out?

I have acquired a "replica" Triumph TRI Harris PRC-152.

The unit came with no battery although the seller later found a battery which was good news. The TRI PRC-152 was part of a silent key sale and the battery was later found with some other equipment.

The unit also came with several TRI "top" battery interface chargers.

The TRI PRC-152 radio has 3 "pogo" pins which connect to a battery.

The battery has a centre pad and an outer ring. Presumably the middle radio pogo pin connects to the battery centre pad (+ve?) and the 2 outer radio pogo pins connect to the battery ring (-ve?). This might NOT be correct.

BUT the TRI battery "top" charger interface only has 2 outer pogo pins with an empty "hole" where a center pogo pin might be located. As a result there is no contact between the TRI charger and the battery centre pad.

The radio came with several TRI charger interfaces and they are all identical with no centre pogo pin...just a gap where a pogo pin should be located.

Does anybody know if the TRI PRC-152 radio / battery originally had different pin outs locations. Maybe the original battery did NOT have the a center pad and outer ring but 2 adjacent pads? If that's the case, then the 3 radio pogo pins might not be -ve for the 2 outer and +ve for the centre pogo pin??

I wondering why the radio came with several TRI chargers which were all missing the centre pogo pin? Can I mod the TRI charger by switching the location of the pogo pins?

Also, can I open the TRI battery and charge the lithium batteries in an external charger (assume they are standard 18650 batteries?).

I mainly collect real Motorola (and Harris) commercial radios and tend to avoid the cheap Chinese replica stuff :)

Its all clear now...thanks to Brooke Clarke's excellent webpages.

The outer ring is NOT -ve (negative)..its the 2 metal outer "lugs" which are -ve

The outer ring is +ve (positive) and the centre pin is used as a "status" indicator in real Harris PRC-152's.

I guess the TRI PRC-152 does not use the centre pin - so there is no need for a centre pin in the TRI "top" chargers.
