Hi David, If it is XV144, there is neither internal fan nor holes in the PCB beneath the fan area.
For XV432, there is an internal fan plus holes under the fan area. As I mentioned in my earlier emails in this forum, I need to modify my XV144 in the way similar to the fan + PCB arrangement of XV432 so as to solve the heat issue. Without these modifications, XV144 will be extremely hot when operating under the power output 20W SSB/CW or 10W continous carrier modes. 73 Johnny VR2XMC ----- 郵件原件 ---- 寄件人﹕ "David Ferrington, M0XDF" <m0...@alphadene.co.uk> 收件人﹕ elecraft@mailman.qth.net 副本(CC) Eric <gliderboy1...@yahoo.com> 傳送日期﹕ 2009/12/14 (一) 11:14:35 PM 主題： Re: [Elecraft] XV-144 heat Are there holes in the PCB Eric?
