Hello I just bought an ampifier KPA500. I have 3 Kenwood radios model TS-870SAT, TS-480SAT and TS-570, I want to confirm with your technical support if both Microham Digikeyer 2 and Micro Keyer 2 are just needed to key my amplifier as stated on the operations manual.
Here's the explanation taken from the User's Manual of Microham products: (7) PA PTT: PTT output for Power Amplifier Ground during transmit, TIP - Signal, SHELL - Ground If the jumper is in the SS position, the switching transistor (open collector) is connected to the PA PTT jack. The transistor can switch up to 45V/0.8A. This position is appropriate for modern Power Amplifiers with electronic keying. Check the manual of your amplifier to be sure the power requirements do not exceed the transistor rating. If the requirements exceed transistor rating set the jumper to the RE position - this position connects the relay contact to the output jack. Maximum rating for the relay is: 48V AC/DC @ 1A. Any help will be appreciated Regards Siso, HK3W ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
