Re: [Elecraft] K-Pod Questions

If your K3S is connected to your computer, the FT232R USB UART is probably the one in the K3S that connects your computer to the K3S's programming interface. There should also be a USB AUDIO CODEC. When I look at my K-Pod which is connected to the computer for power, I don't see anything. It

Re: [Elecraft] Sloping Terrain vs Feedline Losses

You might also consider receive noise, which you can check in both spots (unless you are planning a dedicated RX antenna). As others said, loss for most coax will be much lower than one dB per 100 feet. Vic 4X6GP > On 13 Jul 2016, at 01:16, Dauer, Edward wrote: > > So long

[Elecraft] Alexloop VS P-Loop

Last weekend a friend and I set up a club station at a ham swap. I brought my Alexloop and he brought his P-Loop. We swapped them around and as you would expect, we could not tell if one out performed the other. So I will comment on the most noticeable difference I observed while using them. The

Hi Stan I own an AlexLoop and a few of us hams went into a park and did some signal comparisons on 20 meters. We compared an Alexloop, a full size vertical with four radials, and a 1/2 wave end fed for 20 meters. I used an a/b switch on receive and transmit. The vertical beat out the

Re: [Elecraft] RX Ant Out?

Jim, You are so right about the K3(S) manual!  Elecraft pretty much leaves it up to your imagination on just how to use it the RX Out BNC connector  I found a good use for the RX Out to be where you have a separate receive antenna (Beverage, HI Z 8, SAL, etc.), and plan on using diversity

Re: [Elecraft] RX Ant Out?

When the RX ANT function is engaged, the normal internal connection between the Receiver side of the K3's T/R switch and the Receiver input is broken. The output from the T/R switch is routed to the RX Ant Out jack. The RX Ant In jack connects to the Receiver input. This allows you to insert a

[Elecraft] RX Ant Out?

I can't figure out what RX Ant Out does. The K3s users manual is pretty sparse in it's description. It appears that the "normal" e.g. Ant1/2 is presented to RX Ant Out when the RX antenna is selected. If that is the case then could RX Ant Out be fed to Aux In? That would make the TX Ant the Aux

Re: [Elecraft] Sloping Terrain vs Feedline Losses

Elevated radials will do more by establishing a fixed array configuration on match and pattern.  The orientation of the ground is another issue but with a fixed orientation the pattern will be more subtle.  I run multiple antennas with vertical orientation and find that the ground conductivity

Re: [Elecraft] Problems with band decoder

Instead of the band data lines being loaded down so the logic "1" value is not reached, it is more likely that the RS-232 lines are not being pulled to the logic "0" level because of pullup resistors in the band decoder receiver inputs. If the band decoder that you are using has pullup

Re: [Elecraft] Sloping Terrain vs Feedline Losses

The elevated radials should help reduce near field I2R losses, but the sloping terrain will help far field reinforcement and produce 'gain' in some directions, although at 80M it should slope for further than a mile away to really make a difference. I do not think elevated radials will change

Ted … I think you are overstating the coax losses. Even stock RG-11 should be perhaps 0.3 dB/100ft on 80 meters - around 1.5 dB for the 500 ft. run. Even so, I would probably gravitate toward the closer location. With the elevated radials, the effects of the ground conductivity should be
