On the other hand I alsop wanted to show that you don't need a special tuner to feed a doublet or open line.<br />By the way I doubt you'll notice the difference on air. As a sidenote this is not very scientific, it's a practical test. This is the outcome but it could be that measuring the RF current has nothing to say about the effeciency of both tuners. Unfortunately I haven't got the knowledge of everything. Any comments on this topic are most welcome. 73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.comtag:blogger.com,1999:blog-3676983452144254088.post-59217469647309755912021-02-23T10:48:30.410+01:002021-02-23T10:48:30.410+01:00Thanks Bas.

Two points that I think also relevant: (1) the MFJ is considerably cheaper than the Palstar and (2) it is considerably lighter. Even if the MFJ had proved to be not so good, the price and/or weight issue could, itself, tip the 'balance' (bad joke!)Photonhttps://www.blogger.com/profile/10137649851898638015noreply@blogger.comtag:blogger.com,1999:blog-3676983452144254088.post-32557870270751598292021-02-22T21:41:58.681+01:002021-02-22T21:41:58.681+01:00Tnx Simon, it is a interesting comparisation.

A simple quality 1:1 current balun at the output had done the trick just as well. 73, BasPE4BAS, Bashttps://www.blogger.com/profile/12958141238330445285noreply@blogger.comtag:blogger.com,1999:blog-3676983452144254088.post-27252480234065182812021-02-22T17:08:05.424+01:002021-02-22T17:08:05.424+01:00Nice kit and interesting results non the less. 73 ...Nice kit and interesting results non the less. 73 have fun de Simon M0YKS MØYKS Simonhttps://www.blogger.com/profile/16843311894630055964noreply@blogger.com
