If you want a "multi band" dipole then I would recommend cutting it for the lowest frequency you plan to operate and feeding it with balanced line. Ev

Re: [Elecraft] KX2 Antenna Curiosity

Shu, If you add the 58.5 foot wire to the 16.5' counterpoise, you have a 75 foot antenna. That is close to a half wavelength on 40 meters. You are feeding it off-center which will allow it to be used on several bands (even though one of the antenna wires is on the ground). As I recall, Bruce

Re: [Elecraft] KX2 Antenna Curiosity

Absolutely. The other advantage of a horizontal dipole (or inverted V) is that it will be far quieter than the wire. An end fed non-resonant wire installed as a sort-of sloper “works” but is far from optimum. Especially since you’re using a minimal counterpoise system. One counterpoise wire

Re: [Elecraft] KX2 Antenna Curiosity

The only issue I've encountered with single band antennas, to staff a Field Day site to operate 2 or 3 stations per band, and 5 bands, there needs to be some 10 to 15 antennas erected.    Where as a single 135 ft wire with a balanced feed system, a good 1:1 balun, and a good tuner {not one of t

Re: [Elecraft] KX2 Antenna Curiosity

I'd like to suggest that one very good reason for using centre-fed and external matching unit is because the harmonic pickup from nearby stations is much reduced compared to multi-band antennas. This is best implemented when the antenna is as near perfectly balanced as possible to avoid feedlin

Re: [Elecraft] KX2 Antenna Curiosity

I have a KX3 instead of a KX2, but I frequently go out in the field to play radio at local parks and other scenic spots. I have a number of antennas, but one of my favorites is one I built recently, a link dipole for 40, 30, and 20. It's tuned for the CW portions of the bands, so it doesn't need mu

Re: [Elecraft] KX2 storage temps

Eric,    Batteries do NOT like cold or excessive heat so I wouldn't store the battery in either conditions. 73! Tom - KB2SMS On 11/2/19 8:04 AM, eric norris via Elecraft wrote: Does anyone know what a safe temperature is for storing--not operating--a KX2, with batteries?  32F?  20F?  10F?

Lithium AA batteries are good to -40F or -40C. My question remains. Does anyone know the answer? Thanks. 73 Eric WD6DBM On Sat, Nov 2, 2019, 5:13 AM Tommy wrote: > Eric, > > Batteries do NOT like cold or excessive heat so I wouldn't store the > battery in either conditions. > > 73! > > T

[Elecraft] KX2 output power drop

Hi folks .. A question about the KX2: I saw this on other posts, and also experienced it in portable operations: ''The KX2 was able to pump out a full 10 watts of power for a little over one hour, then as the voltage dropped, it reduced output to 5 watts.''. So it seems to be normal, but is it

The MFJ-18XX series is probably what that was. XX is replaced by your band of choice. The whips are base loaded, and only work on one band. 73 de Ray K2ULR KX3 #211 > On Jul 11, 2016, at 3:14 PM, Phil Wheeler wrote: > > For walking one of the MFJ whips seems a reasonable choice. Wayne did s

Re: [Elecraft] KX2 Portable Ant

You'll also want a counterpoise wire connected to a mini-banana plug inserted into the corner hole on the KX2. It can drag on the ground as you want and if it gets snagged or stepped on, it simply disconnects easily from the KX2. Ed W0YK ___

Has anyone compared the MFJ-1899T (multiband with tapped coil) to the single band antennas? I realize that none of these will compare with a good fixed antenna but are they all equally bad? Bob, N7XY KX2 #385 On 7/11/16 12:21 PM, Ray Sills wrote: The MFJ-18XX series is probably what that was
