Hello Rick, I trust you will get advice from experienced builders here. Here are some additional points, you may wish to consider:
1. If you do not need a one-piece K2/100, you may wish to think about a KXPA100 instead. KXPA100 can work with any QRP transceiver including K2. 2. There is a full description of modification older K2 in elecraft website. http://www.elecraft.com/manual/k2a2binstr.pdf Since I am an overseas user, I bought most of the components locally and did a modification for an older K2 with S/N under 2000. 73 Johnny VR2XMC 寄件人︰ Rick-N8XI <n...@hotmail.com> 收件人︰ elecraft@mailman.qth.net 傳送日期︰ 2014年04月29日 (週二) 7:53 PM 主題︰ [Elecraft] Elecraft K2/10 Upgrade I posed this question on eHam qrp forum and it was suggested I ask the experts here. I am thinking of adding the KPA-100 (Amp) and KSB2 (SSB) options. What hardware/firmware upgrades will I need to facilitate the additions? And... is it worth it? My K2/10 is a 1999 vintage. Serial Number 171.
