I have D Rev and have not yet installed it. I would like to know if there is any advantage to paying the $9.00 for the G Rev. ___________________________________________________________________________ Hi Jim, If you have a fully loaded K2 and only purchased our headers in case you ever needed to remove an option, then there's no need to upgraded. On the other hand, if you have a bare K2 and plan to make it "Plug & Play Ready", then rev. G is something to consider since the headers will be installed permanently. --- - - - --- This redesign was initially undertaken to address "RF concerns" which recently kept one new K2 builder (a retired RF Engineer) from using our "Plug & Play Ready" assembly approach. In addressing this issue we added ground planes, re-routed the trace that replaces RF-W1, and shortened the signal paths on the UN-KNB2. We don't have the instruments necessary to determine whether there's a measurable improvement between rev. D and rev. G. If there were, it would likely only affect the two headers at the back of the RF board since they carry the un-amplified received signal. There is also a mechanical improvement in rev. G with the addition of an UN-KNB2 mounting hole. This might be an advantage if you operate portable/mobile. --- - - - --- There are some subtle changes that only affect assembly. Rev. G has fewer break-away tabs, a bottom silkscreen, and a built-in SIP connector separation aid. For our European customers, the rev. G UN-K60XV has a center ground pad for the Murata ceramic filter 40m narrow BPF mod. Lastly, there are a few things that we just wanted to improve upon in rev. D. All of the text is now right-side up, and the UN-K60XV no longer blocks the RF-L4 (80m BPF) adjustment slug. 73, Gary, KI4GGX K2 #4067 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
