Note that the internal tuner cannot co-exist with the KPA100 amp. The amp uses the space occupied by the optional battery pack and ATU. Installing the ATU/Battery cover with those accessories makes for a nice, one box, QRP portable rig. It's not a huge issue to swap top covers, changing the K2/100 into a K2/10 or back again.
Of course you don't need a heavy power supply for just 10 watts (the rated maximum output from the K2). The difference between 10 watts and 100 watts will be 10 dB (between 1 and 2 S-units at the receiving end). I've never found that to be a problem, but then I'm a QRP guy, Hi! (Note that while some get more than 10 watts from their K2, it is NOT recommended operating voice mode (SSB) at higher power levels to avoid excessive distortion.) The ATU is similar to the other Elecraft ATU's - a high-efficiency L-network with series inductance and shunt capacitance at either the input or load end. One caveat is that the miniature T1 ATU has somewhat restricted matching range on 160 and 80 meters owing to the limited space inside for the inductors required. 73, Ron AC7AC -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of KM6JMR Sent: Tuesday, September 26, 2017 3:27 PM To: [email protected] Subject: [Elecraft] K2 20 watt internal tuner I have purchased a K2/100 and was wondering if the 20 watt internal tuner cover is more or less better for field work or field day. -- ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
