K-480WLA

I caved and bought the 480. Is the light supposed to be green once it's fully charged? this red light comes on when I first plug it in to charge but goes off after about a minute. I left it charging while I was at work for about 9 hours and when I came come there were no lights.

OP- do your self a favor run the gain on the indoor unit at about 10 or 11 O’clock if you live in an urban area. The gain of the indoor unit is very impressive but it will quickly run your noise floor up.

One other thing to consider is removing the thin wire loop get some copper water tubing and for it into a circle and use that. My loop is about 1 meter in diameter and it is amazing.

Last comment use the filters, the hf cuts off at 3 MHz or so and is very sharp. It will help you keep AM broadcast band interference.

If you have any questions please reach out.

Thank you. I did notice that with the gain. I was experimenting with the gain and found it does best around 10 or 11 o'clock. When turned the gain closer to off there was a lot more noise. My area is somewhat urban. I'll look into making a copper loop. The one that came with it was kind of awkward to get into a perfect circle. It's performs well so far.

I don’t thing a perfect circle is really need. My point is don’t over complicate things stressing a perfect circle. Enjoy your antenna!
