• 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.

I'm trying to set up my PiRLP with a Kenwood TK-790 VHF transceiver. These transceivers have a DB-25 connector that has everything you would ever need to connect devises like the PiRLP (headsets, horn relays, etc.). Here is what I've got so far:

PiRLP Pin Kenwood TK-790
1 - No Connection
2 - PTT OUT ???
3 - Aux 1 Out 2 AI1
4 - Aux 2 Out 3 AI2
5 - Aux 3 Out 4 AI3
6 - Ground 18 Earth
7 - COS In 23 Squelch Signal output
8 - Audio In from RX 17 RX audio signal output
9 - Audio Out to TX 13 MIC/data signal input

Does anyone have experience or ideas about this? In particular the PPT OUT from the PiRLP and the Audio Out to TX from the PiRLP? I think the rest of the pinout is correct.

I know that there will probably be some programming changes like activating the external ptt, etc.

Any ideas?

Thanks,

Larry

Thanks. I have that service manual; however, given the fact that Raspberry Pi and Kenwood use different terminology, I am not sure that I have identified the correct pinout. I see in my initial post it may not have been clear, so let me modify it a little here. My main question is regarding the Microphone pinout(s)?

PiRLP Pin => Kenwood TK-790
1 - No Connection => No Connection
2 - PTT OUT => ???
3 - Aux 1 Out => 2 - AI1 (Aux In 1)
4 - Aux 2 Out => 3 - AI2 (Aux In 2)
5 - Aux 3 Out => 4 - AI3 (Aux In 3)
6 - Ground => 18 - Earth
7 - COS In => 23 - Squelch Signal output
8 - Audio In from RX => 17 - RX audio signal output
9 - Audio Out to TX => 13 - MIC/data signal input

You need to set, under edit-> Function Port.

On the 'Input' tab Select 'Ext PTT' in the drop down menu next to 'Radio 1 AI1' (or AI2 or AI3 or AI4, or AI5)

If you intend to use PL(QT/DQT) on transmit, you need to enable QT/DQT on EXT PTT.

Under Edit-> Optional Features-> Optional Features 1

Make sure there are check boxes next to both:

'EXT PTT w/QT/DQT'
'EXT PTT w/Squelch Tail Eliminator'
If you have a microphone attached to the radio, you will also want to make sure 'EXT w/MIC MUTE is also selected.cthis wail mute the mic in the microphone when the node keys the radio. If you do not have a. IC attached, do not worry about this setting.

In your diagram the three AUX in and three Aux Out pins should NOT be connected.
