Free CAD software Hi Jay, Yes, I've used the ExpressPCB schematic and PC board software for a number of years. What's very nice is once you draw the schematic - it can aid you in drawing a PC board design. It has a node highlighter (for lack of a better word), so that when the PCB drawing is linked to the schematic drawing and you click on a node (pin, resistor, etc) all the nodes on components in the drawing that element is connected to will light up. So you immediately know where you have to draw the traces. There are a couple of minor down sides, its library of ready symbols and components is a bit on the skimpy side - but, they do provide the means for you to create and dimension any component yourself. Once you get use to using it, it only takes a minute or two to whip up another component and then store it in the "custom" component library. Also you can not directly produce the PC board industry standard "Gerber files" used to produce PC boards - so you are sort of locked in with ExpressPCB. You can get a Gerber file from them but it will cost you $60. On the other hand, they have some very reasonable board quantity offers (for example 3 boards for $51 - to get this price the boards have to be 3.8"x 2.5" or smaller) and they will get the boards back to you within 3-4 workdays. I'm just finishing up 3 PCB board designs and have sent the first off for them to make. I have probably had 10-13 designs done by them over the years and been happy with them all. I have looked into other PC board manufactures due to the limitations (no Gerber files, no capability to make stencils for surface mount components - yet) , but have not found any that induced me to switch.

Keep in mind that your power consumption goes up quite a bit when you key the mic. Your transponder also has pulsed of higher power consumption. I've heard of guys who set their alarms based on the airplane running with everything turned on. But when they key their mic, especially when the transponder is also transmitting, they get an alarm.

Dissimilar metals, moisture, corrosion, rectification. I've seen bad splices wipe out an entire manufacturing plant's data network, but only when it rains. Check your connectors for white powder and the back of your panel for moisture.

The Lightspeed electronic ignition installation manual specifically states "Do not shrink wrap RG-58". I cannot find anything that formally states as a general rule that RG-58 should not be shrink wrapped or what problems it creats. I would like to perform the simple application of clear shrinking lables on co-located coax antenna leads. Is this acceptable? Can anyone shed some light on this?

Heating will allow the insulation to flow and disturb the geometry of the core element relative to the outer braid, changing the coax impedance. So...don't ;-) And don't squeeze them with Ty-Wraps either. Concerning the coax label, how about a nice little label attached to the crimped metal collar at the BNC connector ?

If I'm reading the graphs right, it did perform rather differently than the previously tested "Batter Minder" (actually a Deltran Battery Tender Jr., wasn't it?) While the "Battery Minder" climbed to not-quite 14.0 and then dropped to float mode, the BT+ appears to have climbed smoothly to 14.2 volts, and then held between 14.2 and 14.4 for a dwell time of over an hour (if the time axis is the same as the earlier test), before dropping back to 13.2 float. This profile is just as advertised on the Deltran website. It's nice when things perform as advertised. Thanks for running these tests.
