No to "slight" Elecraft! There IS a very nice amplifier kit available that works great with the K1! Will do 35-40 watts out for 2-2.5 watts of drive. Uses a pair of power FETs. Has filters for all bands from 160-10 meters. Checkout "HFPacker" search on Google and you will get the link to the website. Nothing is drilled or tapped in the heatsink or chassis! It is truly a "kit" of aprts. PC boards very nice! 73, Sandy W5TVW ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[email protected]> Sent: Sunday, March 27, 2005 12:47 PM Subject: [Elecraft] K1-4 & KAT1
| 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. | Subscriber Info (Addr.
