Also note that the K2/100 automatically sets it's power out to 20W when you tell it to tune. I doin't know if that has anything to do with the LDG tuner's reaction, but it is worth remembering.

Regardless of whether the LDG is on auto or not - the K2 will not initiate a tune. The LDG does tune properly when I hit the manual tune button though. I'd like to know from Wayne or Eric what we SHOULD expect - cause at the moment I don't really know. Can't wait for the new Elecraft tuner.

For example, before I sold my Omni V, all I had to do was plug it into the tuner and it would automatically activate the tuner as soonas I hit tune on the Omni. The Omni was replaced with an Icom 756PRO. The Pro requires a special connection made by LDG before the Icom can work properly with the LDG. So it's not really a question of something necessarily being wrong with the K2/100 - it's a question of knowing what we should expect to happen when the K2 is connected to one of the more common tuners. Hope that made my question a little more clear. Thanks Ken. 73/Tim Ken Wagner wrote: > > Tim: > > I don't have a LDG tuner, but it sounds to me like whatever problem you are > having has to be in the tuner.

The LDG tuners initiate an auto tune by sensing a high SWR. The K2's only responsibility is to put out an RF carrier. If the SWR presented to the K2 by the "untuned" tuner is very high it may be possible that the K2 (in order to protect its output stage) does not put out enough RF in order for the tuner to sense the need to retune. I'm not sure why you needed some special connection in order to use it with the 756PRO unless it was the same sort of problem. You might try placing the K2 in the CW mode and keying it with a straight key to get enough power for the tuner to initiate an auto tune rather than using the K2's tune function (which cuts the output power back). Try it with perhaps a 5 watt output setting on the K2. This by the way is one of the benefits of the SGC tuners. They sense RF frequency and phase in addition to SWR in order to tune. +++++++++++++++ Date: Wed, 28 Aug 2002 10:42:38 -0400 (EDT) From: kc4kgu at ENTERZONE.NET To: Tim and Nancy Logan Cc: Elecraft Subject: Re: [Elecraft] NZ7C: K2/100 & LGD MP-11 questions On Tue, 27 Aug 2002, Tim and Nancy Logan wrote: > Hi folks - > Well, so far everything seems a go with my K2/100.

My first HF station was an Alinco DX70 and an AT11MP. There was a cord that went between the two that allowed the DX70 to initiate the tune function on the AT11MP. So, no - This isn't an SGC. You have to press a button, be it on the rig if you have the appropriate interface between the rig and tuner, or on the AT11MP itself. 73 de John - KC4KGU K2/100 #2490 +++++++++++++++ To: cyr999 at extremezone.com Cc: elecraft at mailman.qth.net Date: Wed, 28 Aug 2002 17:17:02 -0400 Subject: Re: [Elecraft] NZ7C: K2/100 & LGD MP-11 questions From: Michael E Dobson Tim, Make sure you have the LDG set to Auto and not Semi-Auto. I use the same model tuner you have and when I hit the K2 Tune button the LDG relays start clicking if the SWR is too high. Remember, the LDG will not tune automaticly until the SWR goes above 3:1 per the LDG manual so sometimes you have to hit the LDG tun ebutton to get the best match. I hear a beep when I start and stop the tune on the K2. 73, Mike WA3KYY K2/100 #2221 On Tue, 27 Aug 2002 19:12:13 -0700 Tim and Nancy Logan writes: > Hi folks - > Well, so far everything seems a go with my K2/100.

This is doable from a >Pegasus, certainly thought I could do so from a K2 as well. Looking at the Z-11 manual, I see no provisions for remotely controlling the tuner, so on a band change the Z-11 will need to told to retune. It is fairly easy to have a computer tell the K2 to enter tune mode, as long as the KIO2 is installed. Simply have it send a 'Tune' key emulation command, which is essentially the same as holding the TUNE button on the K2's front panel. I doubt you will be able to duplicate the operation of the KAT2 tuner with the Z-11 because of the lack of control ability on the Z-11. Good luck, and let us know how you do! 73, -Jack Brindle, WA4FIB ======================================================================= MacDobs - helping to shift the paradigm for low-cost amateur astronomy. ++++++++++++++++++
