Re: [Elecraft] KX2 Battery Question

Sorry, not Kapton. You're looking at conductive tape available from a web site called kaptontape.com, unrelated to the Dupont product. This is Kapton tape from the same website: https://www.kaptontape.com/1_Mil_Kapton_Tapes.php 73, Josh W6XU Sent from my mobile device > On May 27, 2017, at

Re: [Elecraft] KX2 Battery Question

You must be confusing Kapton with a different material. It has excellent dielectric properties, makes an excellent insulator, and is a pretty good thermal conductor. It's also inexpensive. It's lousy with abrasion. 73, Josh W6XU Sent from my mobile device > On May 27, 2017, at 2:13 PM, Matt

Re: [Elecraft] KX2 Battery Question

Someone mentioned Kapton tape earlier, to be used to insulate the battery side of the PCBA. Kapton tape is conductive and used mostly for EMI shielding. Putting it or other tapes (some electrical tapes) on the the PCBA would probably change electrical characteristics - conduction between

Re: [Elecraft] KX2 Battery Question

There are no components anywhere near the battery. The bottom of the RF board in this area was left completely clear specifically to avoid the need for any supplemental insulating material. 73, Wayne N6KR > On May 27, 2017, at 10:14 AM, Peter Pauly wrote: > > I would have

Re: [Elecraft] KX2 Battery Question

I would have liked to see a big piece of kapton tape covering the board. Aren't the components ESD sensitive? On Sat, May 27, 2017 at 10:23 AM, Tim McDonough N9PUZ wrote: > On 5/27/2017 12:14 AM, Wayne Burdick wrote: > >> I have a "new to me" KX2 along with the internal

[Elecraft] KX2 Battery Question

I have a "new to me" KX2 along with the internal battery and charger. Inside the KX2 battery compartment, is there supposed to be any sort of insulating sheet or pad covering the circuit board? There was nothing inside mine when I opened it and my first thought is that even though it is
