Sidebars are a visual indication of signal distortion .. not the power
level being transmitted. You have a signal *quality* issue which is most often caused by overdriving .

Gerald, Ron and all,
CAUTION: That document's rig setup is incorrect for Elecraft gear. Following the transmitter setup described in that (and many others on data modes) will not allow the K2, K3 or KX3 to function properly. and may (in fact) may create a distorted signal - it is a sure way to create power creep on your digital signal. You must first set the audio drive power For the K3 (or KX3) set to DATA A submode and either turn the power down or turn in TX TEST. Now adjust the audio until you see 4 bars solid on the ALC meter - the 5th bar could be flickering slightly (this is NO ALC for the K3 and KX3 -ALC starts at the 5th bar) For the K2, adjust the audio until you see an ALC indication, and then turn it back a bit. That is it - adjust the *desired* power level with the power knob and operate. Setting the power level to max and using the audio drive to bring the power up to the desired level will work with transceivers that do not use a feedback control loop to set the power level - the K2, K3 and KX3 *do* use a feedback loop, most other transceivers just adjust the drive and take whatever comes out of the PA stage. 73, Don W3FPR On 4/30/2012 2:34 PM, ron wrote: > On 04/30/2012 02:06 PM, KC6CNN wrote: >> I am now up and running on psk31. >> I had my power set to 25watts and all is well.

Ron,
For what purpose is 25 watts more than enough? I can tell you it isn't enough to try and work VU's and other Asians under many conditions from the east coast on PSK. The are times that no amount of legal power will suffice-- e.g. trying to break through an EU curtain to some rare one. The power you need is the power you need. 73 de Brian/K3KO > 25 watts is more than enough power, also, you need to turn down the > mike/audio out gain, it is too "hot". > > 72 > Ron, wb1hga > "QRP, when u care to send the very least" ----- No virus found in this message.

The problem isn't so much that your signal isn't getting there but rather
that the local noise conditions (and pile ups) make it difficult for the DX. Rick wa6nhc "I will find a road; or make one."

Gerald,
You do not say what type interface you're using (i.e. SignaLink, RigBlaster, etc.). Regardless, sidebars on your signal is indicative of you overdriving your transmit audio - not too much power. As long as I do not overdrive my transmit audio, I can run 100W without sidebars and do so regularly on WINMOR. Check your ALC. It should be not more than four bars with a flickering fifth bar. On my SignaLink, I adjust my transmit audio with the TX pot on the front. I can tweak it a bit with the mic gain. 73, Joel - W4JBB On Apr 30, 2012, at 13:06, KC6CNN <[hidden email]> wrote: > I am now up and running on psk31. > I had my power set to 25watts and all is well.

> The power you need is the power you need. Yup. This morning about 11Z I was trying to work a guy in FL on 160M JT65. His noise level was so high that I had to drive the KPA500 to 500W to make the QSO. I've had similar experiences with many other stations that were as much as 10dB above my minimum copyable signal level, starting off with 10W and increasing power in 3dB steps until they hear me. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
