Gentlemen: I just completed KX-1 #1176. Everything checks out fine, life is good, I'm thrilled. I've also just finished a DL-1 dummy load kit. I was concerned that I might be getting low power out on the KX-1, and it appears that the DL-1 has confirmed my concerns. According to the formula provided by Elecraft with the DL-1, I get the following results: V (DC) 7.87 Calculated P (watts) 2.54 (POWER((B2*1.414+0.15),2))/50 I'm using the formula (above) as written in an Excel spreadsheet. 7.87V is the reading on the DMM when connected to the test points on the DL-1. 2.54W is the calculated power. I'm powering the KX-1 with an external 12V battery -- DMM measures 12.85V out on the battery (and the battery charger indicates the battery is slightly overcharged). I finished the KX-1 about ten days ago, and I waited to post this note until the DL-1 came today (and I popped it together). I have not gone back to the manual to review the troubleshooting procedures, and I've not exhausted all possibilities on my end. Yes, the potentiometer accessible from the bottom of the KX-1 is cranked...but that's about it in terms of real checking. Is 2.54W acceptable with 12.85V supply? Have I done something wrong? I'm a relatively new HAM, and I'm a very, very, VERY new QRP guy...2.54W is making me very nervous. I prefer 5! Any suggestions would be most appreciated. Thanks! 73 -- JAY K2TRU _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
