I thought I could at least *try* the trial version legally, but I guess I sprung a booby trap! Drats! The web page said I should try the trial version before I buy the full version. Do I really want to buy Mixw 73, Chuck

Hi Chuck, The attachment worked ok here for me. The sound seems to be saying 'trial' in a female voice. It sounds like a piece of applications software or your driver is doing this. Have you tried killing off processes using task manager to see if you can isolate what is causing it? 73, Brett -- === Brett Rees VK2TMG http://lisp.homeunix.net
Re: [digitalradio] Digital havoc with devices in car
Thats interesting. I tried several earlier trial versions and all of them worked full bore for 2 weeks. After that, if you tried to use them, you got a pop-up that made you wait for a timer to reset before you could do anything more. They still worked if you didnt click on a spot, but that spot set the timer every time. Danny Douglas N7DC ex WN5QMX ET2US WA5UKR ET3USA SV0WPP VS6DD N7DC/YV5 G5CTB all DX 2-6 years each .

I hope it will not say Full every four seconds if I buy the Full version. Hmm? What software does everyone use for digital? 73, Chuck AA5J

Michael Hatzakis, Jr MD wrote: I’ve got a couple of TNC’s and radio’s in my car that I like to operate with backup battery after the car’s ignition goes off. I use a charging circuit to keep the battery charged when the car is running. This is my problem: when I start the engine, the ignition noise causes havoc with the TNC and other digital devices. Is it ignition noise or power glitches? What brand and model of TNC's are you using? Because some Kantronics TNC's may use an internal 9V battery as backup, and prevent the TNC to go nuts with the power glitches. Check the schematics of the KPC-3 and KPC-9612. I have tried chokes, filter caps etc. But the spikes are too broad. I tried a timed delay circuit for delayed switchover, but this causes too much complexity. I tried using a diode so devices can run on the filtered battery voltage while charging from the mains, but the voltage drop prevents proper charging. Did you use POWER Schottky diodes? They have lower voltage drop. It might be interesting to consider the power on switch of the FT-757, which uses a relay actuated by a circuit protected by a diode in series. The relay won't close with low voltage or reversed polarity. Any other ideas on how I can make this work? You have batteries, and you should not allow the starter to draw power from them. Otherwise, with no batteries, one large ESD (say, 1 farad @ 16 V) might help. It is what some people with large audio power amplifiers to have some local power reservoir close to their monster amplifiers. But if your problem are power glitches, and might very well be the case, you should isolate your radios and TNC's from the main battery during startup. How is the health of your main battery? Maybe a portable digital scope hooked on top of it might reveal what happens during startup...it is just a different kind of EKG...
