I would like to see (LED) the state of the BAND0-3 outputs. Has anyone built or bought some kind of 4-indicator for this? I want to do this as a temporary indicator while I am playing with a pair of UM BCD-14 band decoders.
The BAND0-3 outputs come off of 5V through 2.2K pull-up resistors with a 220 ohm resistor in series with the output on the ACC socket. It would seem standard 20ma LED's would not work here with the 2.2K resistor inline. Maybe a diode inline to isolate with a separate supply on the LED's or use some very low amperage LEDs or drive a Mosfet which drives a LED? The 0000 output on the KIO3 for 60M has me concerned. I want to make sure it doesn't cause me a problem when switching between 160-2M and between auto antenna selection and manual antenna selection. Tnx for any feedback. 73, N2TK, Tony ______________________________________________________________ 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
