Hello, Fellow Elecrafters: I've completed and installed a KAT1 ATU in my K1-4, s/n 1453. I'm surprised and pleased that in addition to effectively tuning the antenna & coax for lowest SWR, the ATU acts as a "preselector" and improves the gain of the receiver slightly. All 4 band seem just a bit "brighter" after tuning with the KAT1.
I've read a discussion recently about moving a jumper on P3 on the RF board to activate the KAT1. My instructions don't mention this. I'm wondering if I'm missing something. My RF board is Rev. E, and my KAT1 manual is Rev. C (Jan. 18, 2001). I did leave one end of resistor R3 unsoldered, as instructed in the KAT1 manual. I observed a few minor "discrepancies" in the KAT1 manual that are not covered in the errata. For example, the manual says to install a 3-pin and a 10-pin female connector on the K1 filter board. However, these parts were already installed when I built the K1. Perhaps the extra connectors were supplied in case you had an additional (older?) filter board? It would be helpful if the errata mentioned this. Now I'm looking forward to my next Elecraft project - "booties" for my K1. I'd like to see an Elecraft KPA-1, an external amplifier for the K1, for fixed station use. It would have at least 10 dB gain, with an in/out switch and a row of leds to indicate peak power. I know this will be heresy to some Elecrafters, but the extra oomph would help working DX pileups! Are you listening Wayne? 73, Jim K5HO _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
