Hi and sorry about the bandwidth. I recall receiving a query about the T4 alternate winding ratio within the past week, but cannot locate the email to respond properly.
The normal winding ratio for T4 is to be used. It must NOT be used if the KSB2 option is installed. In other words, it can only be used with a CW only, QRP only (at 5 watts or less) type K2. While the alternate QRP winding of T4 may produce greater efficiency at the 5 watt level, if used at levels above 5 watts, the efficiency is actually reduced. In other words, I do not recommend that the alternate ratio for T4 be installed on any K2. I have seen several that have this modification that have been sold, and the buyer adds the KSB2, then wonders why the K2 "acts funny in transmit" when used for SSB. If the original person asking this question has any more questions, please contact me off-list. 73, Don W3FPR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
