[Elecraft] Using KX3 with MFJ-1899T

[Ronald Nutter]

I have ordered a MFJ-1899T and had similar concerns about the potential 
weight on the connector.  I went with a MFJ-332B mag base with BNC 
connector.  When traveling on business, I will usually have a rental 
car.  This will let me use the car as a base for the antenna.  I was 
trying to find a compact solutions as possible to take with me.

May eventually try the single band antennas, I have only found the MFJ 
versions. Seems the Maldol ones arent made anymore.

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:

> 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
