Further tests on the other repeaters will be performed as the opportunity presents itself. Discriminator Tap While there isn't currently any test equipment on the market that can encode and decode D-STAR, there are some work arounds. Right up to the modem chip, the RX radio is still an FM receiver. So, all the standard tests can be done to check the RF Icom ID-RP4000V Digital Repeater USB of the radio by utilizing the discriminator audio prior to the modem chip.


In the RPV, this is relatively painless. If you remove the top cover of the RX radio, you will see the RX interface board. Near the middle of that board is the CMXA modem chip. Icom ID-RP4000V Digital Repeater USB near that chip is a test pad labelled "DET". Yep, you guessed it, that's good old FM Detector audio. They probably could not have picked a worse cable for this application. It isn't the loss that is a problem about 0. These are the factory installed jumpers: These jumpers happened to be surplus out of another application, and fit the bill.

They are N f bulkhead on one end, and SMA m on the other. A high quality SMA f -N m adapter was used to attach to the radio. Since there is so much room inside the chassis, you would be well advised to add a tuned RF preselector in front of the receiver to try and keep some of the "crap" out. We use an external Sinclair Laboratories receiver multi-coupler ahead of ours Icom ID-RP4000V Digital Repeater USB contains a bandpass filter and pre-amp.

It makes a BIG improvement. On low power, the radio puts out 2. On high power, it puts out Instead, all you have on the front panel is a nice, green LED to tell you that the power is on.

It is confirmed to work with this unit. Open up the repeater to expose the radio unit. You will also need to open the top cover of the radio unit to expose the logic board.

On the logic board, near the front of the repeater, you should see three series of three through-hole plated vias. Since the bias resistors and drivers are already installed, all you have to do is install some LED's! Our prototype used a bi-color, common cathode LED.

We connected the green anode to the RX line, and the red anode to the TX line. This is a picture of our prototype Icom ID-RP4000V Digital Repeater USB "proof of concept": The factory power LED is pretty much an idiot light. As long as the fan is running on the back, there is power. We re-located the power LED from the top of its PC board to the bottom you'll need to rotate it degrees so the pinout is correct when you do this. An Icom DV radio would ignore the data stream and remain silent. I don't know the exact details of this protocol and how it will work with existing repeaters.


I would presume that the D-Star header would remain the same. Bit 7 of Flag One in the D-Star header distinguishes between voice and data communications.
