The most important parameter for a receiving antenna is noise immunity. Any unbalanced antenna like an OCF or end-fed wire is a poor choice. Any indoor antenna is a terrible choice, because it will be

Alan, QRM is the reason for wanting to go outside as inside all kind of power supplies happily buzz along. I have literally checked each of them and replaced a substantial number but the? alarm

Eric, For RX often getting the antenna, whatever it is, as far away from QRM as possible is the most important thing. I'm in a quiet situation so I do not find the performance an amplified loop close

The interfaces & LEDs on my just-completed QLG1 board work as expected.? However, the measured time-to-first-GPS-fix values are much longer than those listed in the YIC5 data sheet: Acquisition Time:

Thanks for all the advice. This is what I understood. For receiving only the resonance is not that important so an end-fed wire with some form of ground or counterpoise (random piece of wire hanging

Yes, there is no answer. Many of us have tried someone's favourite antenna and discovered that in a different backyard it does not work well at all. Even "working well" depends on what you want, DX or

Hi Erik, If you're just receiving then the antenna won't be radiating (unless you're transmitting.)? You'll probably find that the G5RV will work pretty well for your purposes, though you might also

Erik Try what you describe as it should radiate. Its not unusual for our antennas to be non ideal. With close spacing the ladder line will radiate less than the aerial.? being at a right angle even

For a receive only situation many would say the mag loop would be your best bet. With your application being receive-only much of the concerns raised really effect transmitting and matching.

Vince, You are not receiving WSPR signals. What do you see if you remove the audio lead from the RX? Do not take it out at the computer end, that can confuse if Windows thinks there is nothing there.

Hi Hans :), Well said Hans. I used to say that my customers dragged me kicking and screaming towards success!! Keep up the good work!! I am trying to get FT8 up and running. Whoops!! Now there is a

Thanks Alan for the reply. This is what I have: U3S Settings: 0]? 0? 014,083,600 RX??????????????????? 12? 0 ------------------------- 1]? 0? 014,083,600

Hello Eric, Take a look at this solution from Palomar. No other parts needed except coax and the wire. We used about 50' of RG-58 and it worked well with 100 watts. Palomar has a number of solutions

Good day Erik; ? Years ago I put up a Mini G5RV when I was living in an apartment. The 300 ohm twin lead came off the flat top at about a 45 degree angle. My first G5RV which had a 102’ flat top

Till now I have used the received module with an amplified wide band magnetic loop. Now I'm looking into a dipole. Due to space constraints and stealth requirements the 1/2 size g5rv multi band dipole

Hi Ken, I like the case nifty idea certainly makes me want to look at other ideas for the enclosure. I see you have set your U3S for 6/4/2m bands just wondering which transistor the IRF510 or the

Vince, You are seeing the signals, lines 1 minute 52 seconds long starting exactly on the even minute? 20m is open? You do have the U3 calibrated correctly? Or, do you mean you are decoding spots but

Hi Justin I wish I could have something useful to share but unfortunately I do not... I do not consider myself well organized or managing time well. Too much going on, too many balls juggling at the

Hi Hans,? would you be willing to share how you managed to learn the time management skills necessary to accomplish all that you do?? from where I'm sitting it seems to be a great deal of stuff!?

Hi Justin You cannot. Only SiLabs can prepare a chip with this "non-volatile" start-up configuration programmed. And you probably have to order 100,000 of the chips or something crazy, to get them to
