Re: [Elecraft] Tuning AL-811H
Thanks to everyone for all the suggestions. I tried using RTTY mode this evening, and it works like a charm. Now I just need a watt meter to measure the output. Fortunately, Wayne and Eric make one of those, and I should have mine mid- to late week next week.

[Elecraft] Tuning AL-811H
I have a question about tuning an AL-811H amplifier with my K3. When I used my FT-857D in the shack, I would tune to the antenna in FM mode. However, I don't have the FM filter on my K3. I tried tuning the amp using AM, but I don't have that filter either. So, what is the best mode to use that allows me to briefly transmit an uninterrupted carrier so I can get this amp set up and the settings written down? BTW, after going through this, the saving for the KPA500/KAT500 will soon begin. Thanks everyone for the assist. 73, --Ian Ian Kahn, KM4IK Roswell, GA km4ik@gmail.com K3 #281, P3 #688 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] Tuning AL-811H
Jeff, When I try to use CW, all I get are transmitted dits or dahs. The breaks register as zero output, so the needles on the amp bounce around and are hard to read. Any suggestions on using CW to generate that continuous carrier out to the amp so that the needles don't bounce around and I can adjust it properly?

You can program the power out of the K3 to be a specific value when you push hold the XMIT/TUNE button. I have mine set for 5 watts for initial tune-up of the amp with a steady carrier.

Re: [Elecraft] Tuning AL-811H
Ian, That is because you are using the paddle input. Use the Hand Key input. If you do not have a hand key, get yourself a 1/4 inch stereo plug - connect one wire to the tip and another to the shell - on the other end of those wires, put a pushbutton, or a toggle switch or whatever you desire to use - in any case, shorting the two wires together will cause the K3 to transmit in CW mode. As has been mentioned already, you can also use TUNE, and there is a menu item to set the TUNE POWER should you choose to do that. 73, Don W3FPR On 1/19/2012 11:04 PM, Ian Kahn - Ham wrote: Jeff, When I try to use CW, all I get are transmitted dits or dahs.

Re: [Elecraft] Tuning AL-811H
Ian: With the key connected to the paddle input, hold the key down on the dit side at 30-35 wpm. Then tune your PA. The needles won't be bouncing all around the scale.To get an exact readinghold the dah side down at slowest speed you have.Works fine, lasts a long time.

Re: [Elecraft] Tuning AL-811H
If you are interested in doing the job totally right when using SSB, the only way to be assured of good linearity in the amplifier, is to use a two-tone test oscillator fed into the audio input and a monitor oscilloscope that gives a trapezoidal test pattern. Yes, I know a lot of people use a CW carrier to do that and are successful at least some of the time. It is easy to mistune this way and NOT get good linearity and maximum `PEP output however. This degrades your signal and often times may disturb QSO's up or down the band with non-linearity products. Cheapest test scope used to be the Heathkit SB-610 which has a built in 2 tone test oscillator. I think Yaesu and Kenwood also made these as well. Once you get used to the procedure it is easy and fast and assures a very clean and potent signal. 73, Sandy W5TVW -Original Message- From: Ian Kahn - Ham Sent: Thursday, January 19, 2012 9:51 PM To: elecraft@mailman.qth.net Subject: [Elecraft] Tuning AL-811H I have a question about tuning an AL-811H amplifier with my K3.
