Re: [Elecraft] KX1 with HF Packer Amp
Paul, With 2.4 to 4W out on your KX1 it sounds like you are running the KX1 on 13.8v. Rather than adjusting the power out pot, which has a limited lifetime according to the manual, try running the KX1 on internal Lithium batteries (the Energizer ones that Elecraft recommends) and the drive should be just right for the amplifier. Also, for portable use, I don't uset the straight-fed wire antenna that the manual suggests for the barefoot rig, but instead a vertical a few feet away, or a doublet fed with twinlead. The T1 tuner is OK for 35W with it for CW but I wouldn't run a contest with it. 73, Leigh/WA5ZNU On Mon, 6 Feb 2006 5:17 pm, Paul Webb wrote: Some discussion lately on using the K2 to drive the HF Packer Amp.

My KX1 puts out 4 watts on 40 meters and 3.5 watts on 20 meters. Should have plenty of drive for the Amp. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KX1 with HF Packer Amp
That may be TOO much drive for the HF PAcker! I drive one on 160-20 meters with a K1 and it takes about 1.5-2.0 watts to make the HF Packer deliver 35 watts out. If you can't control the power output of the KX1, then you may have to change the values of the attenuator network in the input path of the HF Packer on the RF board therein. I have had fantastic results from my HF Packer. Only complaint is it needs a bit of modification of the hang time. Needs to be much shorter! OK for SSB but no good for CW contest/net activity. Ok for casual QSO's. Hang time once keyed is much too long for CW. 73, Sandy W5TVW - Original Message - From: Paul Webb [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Monday, February 06, 2006 12:04 PM Subject: [Elecraft] KX1 with HF Packer Amp | Some discussion lately on using the K2 to drive the HF Packer Amp.
