Keith Ennis (KV5J) is proud to introduce the second in his line of Digital Display Units. The Digital Display Unit for Elecraft's KPA500. For the Elecraft KPA500 I have designed a compact, easy to read Digital Display Unit (DDU). It allows the monitoring of five crucial readings all at the same time. 1. Power amplifier's heat sink temperature2. Power amplifier's high voltage supply voltage3. Power amplifier's current4. Power amplifier's output power5. SWR that the KPA500 sees at its output The DDU measures only 4X4X2 with an easy to read 2 line display that can be located at the operating position and the KPA500 located up to 10 feet away. The DDU is designed with the following features: Easy to read 2 line displayNo USB or serial cable to computerNo com port in Windows to manageNo computer neededPlug and PlaySimply connect the supplied DC power cable to power supply and PC data jumper cable to the KPA500Retains all functions of the KPA500 front panelAll displayed info obtained directly from the KPA500 The DDU will poll the KPA500 and display PA voltage and PA temperature during receive and transmit cycles. It will add watts, SWR and current during transmit. There is a built in hold time to keep the watts and SWR displayed for a short amount of time after unkeying the amp.

With any USPS luck I will be taking delivery of mine today unless delayed. Will report to the forum how I like it...

It would be handy if it repeated the rs232 so you could leave the computer hooked up for the utility.

"It would be handy if it repeated the rs232 so you could leave the computer hooked up for the utility."
I doubt any design change would be required. The display device would simply have its TX line disconnected and it would listen to KPA500 responses to utility polling. In my system that's done with a multiplexing relay so it can be used with or without the utility with no cable re-configuration. In my opinion the parameters that are useful when monitoring a KPA500 are PA dissipation and PA efficiency. This device displays neither.
