I do the same Rick. However, when new firmware comes out, I update my manuals appropriately. Elecraft allows that, unlike Icom, Kenwood, or Yaesu. I wonder why? Refreshing my own "firmware" is much more challenging, especially for things not refreshed by use. Many questions on this reflector

I am using the same unit as Lyn (BD4116) on a center fed 250’ doublet Inverted Vee with about 50 feet of 600 ohm open ladder line and about 15 feet of 50 ohm coax. The KAT500 matches all bands except 6 to 1:1. 6 is matched to 1.3:1. I have been told by some that the hybrid unit is worthless,

Henk, I looked at this issue and it is a K3/K3S issue. I was able to setup 2 transverters (XV1 and XV2) on the same band and switch between them when the band change was initiated from the K3 front panel. When a frequency is sent via RS232 connection, it appears the K3 wants to determine what

I have a 9700 and since it looks nearly identical to 7300 assume the UI is similar. Intuitive? Not at all. K3 has lots of buried items but they are easy to find and mostly set once & forget. Only gripe would be all the abbreviations, but that was obviously limited by a practical display choice

No. At low frequencies hysteresis loss dominates. Soft ferrites have high resistivity. Eddy currents increase with frequency but 160m is still fairly low. In SMPS transformer design we look at applied volt*seconds. When the applied v*s goes up, as would be the case with high SWR, you push

That is not true, except at full power. The manual clearly states power levels at 10:1, 5:1, and 4:1 VSWR's for different frequency ranges. RTFM is a wonderful acronym to follow. I'm always surprised to read "I think..." "I recall..." and similar posts to answer a poster's question. Most of us

Hi Jim Thanks for the new link. I must say we made several big chokes using the "old" method and our analyser wasn't good enough to measure the common mode impedance, so our conclusion was they were all above the analyser limit of several thousand ohms. I'm about to make a single core choke,

It is certainly not a clone. It draws more RX current. It is a thinner. The panadapter is built in. I didn't spend enough time looking at it to form a judgement other than it appeals to the same uses as the KX3 and is not a clone. 73 Bill AE6JV On 9/3/20 at 1:58 PM, johna...@gmail.com (John
