That mobile whip is only half of an antenna. When used on a vehicle, the metallic parts of the vehicle provide the other half, a path for return current, which is called a counterpoise. If you provide no counterpoise, return current will flow on the outside of the coax down into your shack. The solution to your problem is to 1) provide that counterpoise, possibly in the form of one or more resonant radials (more is better); AND 2) put a proper ferrite choke at the antenna feedpoint so that the coax doesn't carry return current.

Re: [Elecraft] K3 Amplifier Drive Inconsistency
Thanks for the suggestion. The antenna is less than 25 feet from the rig. The RF getting into the audio could be coming from the coax or the antenna, no way to say which. There is 5-6 turns of coax, 6 inches in diameter, a couple of feet from the rig where it comes into the apartment. Beads on the coax might do the trick, but I am not near my parts boxes, they are about a 12 hour each way drive away. And I am in very rural North Dakota, would have to order something mail order and wait till pony express gets it here. So I will stick with what works. I am in a tiny apartment with just a little patch of weeds with a little grass on it and can't get the antenna any further away. I had the same problem when I tried a short dipole with a fair balun (elecraft of course) at the feed point. And, as I said, I now have zero problems. Well, other than a crappy antenna setup.

Re: [Elecraft] K3 Amplifier Drive Inconsistency
Jim, That sounds like RF getting into the audio. Try moving the ferrites to the antenna feedpoint to choke off the RF on the coax shield. Yes, the coax from a vertical needs a current choke. In fact, you may need a 2nd choke at the shack entry point as well. The coax will try to be an additional radial and that means it will have RF current on it - if not from the antenna itself, the radiation from the radiator may couple with the coax shield and cause RF on the shield (that is why the additional choke at the shack entry). The KX3 has one characteristic that may cause confusion. If the signal to the mic input is too large, the KX3 will shut down the audio gain giving the impression that there is not enough audio when in fact there is too much signal at the input. 73, Don W3FPR On 8/5/2019 9:23 PM, Jim Rhodes wrote: Last night I noticed I had little to no output from my KX3/KXPA100 combo especially on 40.

Re: [Elecraft] Serial port problems
Many USB>Serial cables contain counterfeit chips. The legitimate makers fought back by installing driver instructions that disable the counterfeit. Maybe your update finally caught up. The Elecraft cables are legitimate. Don't buy cheap knock-offs from the Internet. k4ia, Buck K3# 101 Honor Roll 8B DXCC EasyWayHamBooks.com On 8/5/2019 9:49 AM, Gary Tuck via Elecraft wrote: The culprit was the serial/USB cable.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?
Bret, I’ve just submitted a review of the AX1 to Practical Wireless magazine, which should appear be in the October issue, published end of September. I found it worked well on the tripod. The key to getting the most out of it is to let the counterpoise wire fall to the ground about 3 ft or so from the radiator. As a very short base loaded antenna, I don’t think an extra foot or so of height will make a lot of difference. Your extra counterpoise wires is probably the best thing to do. More details in the article 73 de Joe MW1MWD > On 4 Aug 2019, at 18:20, MaverickNH wrote: > > I've got my little 20m AX1 and 3 tuned counterpoise wires on a 4ft tripod > with wires extending to plastic chairs 3ft off the ground too.
