Thanks Don, perhaps, I may be too greedy to go for a multiband 1899t

I don't like mounting the whips directly to the radio with a right angle adapter . not sure if the antenna is holding the radio or vice versa, but the weight does seem to put a significant load on the rig's bnc connector. so I made a little bnc base out of scrap aluminum, and use it portable when it's not convenient or practical to string up a random wire. the setup works, but not as well as random wires, so it's a backup system at best. I have a few photos of the aluminum bnc base posted here which will give you an idea of what I'm talking about: http://www.udxa.org/gallery/show_thumbs.php?id=29 73, Don, N5LZ ----- Original Message ----- From: "Johnny Siu" <[email protected]> To: <[email protected]> Cc: "Elecraft" <[email protected]> Sent: Thursday, July 05, 2012 6:37 PM Subject: [Elecraft] Using KX3 with MFJ-1899T Hello Elecrafters, I tried to use this portable telescopic antenna with the right angle BNC adapter. However, the whip is quite heavy and cannot stand on its own without falling. I trust this has been discussed before. Any solutions on the set up this portable whip? Meanwhile, I finished building the KX3 kit and faced some problems in the TX gain caliration. The calibration began at 1.9Mhz but stopped at 5.3Mhz with an error message of high SWR in the ANT. However, I am using a dummy load for the calibration. The same dummy load was used in the calibration of K3 in the past. What is the likely problem for my KX3? The KX3 was powered by a 12v 7Ahr lead acid battery TNX & 73, Johnny VR2XMC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
