Yes I know that Don, the purpose of the test was to see how much overshoot we got with an CESSB processed audio verses with normal audio and compare them. As part of my experiments I needed to see how much influence the audio drive level had and tried different audio drive levels from 0 to 5

Re: [Elecraft] OT antenna question

I'm always fascinated by those which use of a 4:1 balun when 450 ohm line is used. In most all cases, the 450 ohm line is operated at a known high SWR. The nature of 450 ohm line {or other line such as 300 ohm or 600 ohm, etc.} is that it exhibits much lower loss when operated at a high SWR

[Elecraft] P3 TX MON with AM?

2016-01-13 Thread Barry N1EU
Is anybody using the P3 TX MON to monitor modulation waveform with AM transmission? I'd appreciate comments on how effective a tool it is. I've only seen one video on youtube of a cw xmsn, and it appeared that the P3 captured a transmit waveform and displayed it (like a storage oscilloscope).

[Elecraft] Remote a KAT500

Has anyone remotely mounted an Elecraft KAT500 in a weatherproof enclosure? My current antenna situation is an MFJ-994BRT fed with 100 feet of 9914F and then either a 30’ length of 9913F or 450 ohm ladder line to any variety of 60 foot dipole antennas. I would like to replace the tuner with a

Generally good info snipped: Actually at *any* length, other than multiples of one-half wavelength, there is always some impedance transformation in a mismatched line. On 1/13/2016 5:40 AM, Bob McGraw K4TAX wrote: The feed-line basically reflects the impedance of the antenna from the feed

Re: [Elecraft] OT antenna question

Vic, Your antenna has a very low feedpoint impedance on 40 meters. The 30 feet of open wire line plus the 3 feet of 450 ohm is close to a quarter wavelength on 40 meters. That feedline length should transform the low impedance of the dipole to a higher impedance, so the choice of a 4:1

I'm interested too. I will be running K3/KPA500 to a flag pole antenna, hopefully with the KAT500 at the base. I will likely power it with a separate cable that will have room for control lines too. In the meantime, I am back on the air, remote to W7RN. 73, Fred K6DGW - Northern

Hello again, BTW don't use 9913 cable. It is susceptible to water ingression causing higher loss. All the coax at my site is from Times Microwave. The substitution for 9913 would be LMR400. There are several variations of this cable depending on use. AB2TC - Knut Hi Michael. You bet. See

Thanks Knut. The cable is actually Belden 9913F which is filled much the same as LMR-400 but has a stranded center conductor. I will search for your articles with earnest, It appears from the photos that you only have the PC port connected which should be easy to accomplish. Michael Blake
