[Elecraft] Using KX3 with MFJ-1899T

[Don Butler]

Hi Johnny,

I use the MFJ telescoping whips with my KX1 and KX3, but I opted for the 
single band antennas (17m, 20m, 40) rather than the multiband 1899t, which 
is much larger and heavier... 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:

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,
