Re: W8TEE Mag Loop Testing
Al just ran 100W through it for 2 minutes and "shot" the temperature...no heating or arcing. Jack, W8TEE

Preliminary results -- W8TEE/AC8GY Mag Loop Testing
All: Conditions were not ideal, but we did get some RBN reports. While it's far too soon to say much, it appears the mag loop gives up about 1-2dB over the EFHW, which is up about 60' or so. VE8JY in

Re: W8TEE Mag Loop Testing
I have a similar loop on my mantlepiece right now. It's not made of rigid copper, and isn't a multi-turn loop. It's about a 3.5 foot loop of plastic pipe strap, with 1/2" wide conductive-adhesive

Re: W8TEE Mag Loop Testing
Luggable is right. Is the coupling coil both rotatable and positional ? Is there any switching between 1 turn and 2 turns ? Don't see any advantage of parallel windings except a little less resistance

W8TEE Mag Loop Testing
All: Today we began testing Al's new mag loop (ML) design, shown here: It's a 40-30-20M "luggable" loop. It's about 3' in diameter, breaks down so it fits in a car, and we can get almost 1.1:1.0 on

Re: Storm Damage
Al (AC8GY) has a drone with a claw drop on it and it was pretty easy to put the EFHW up...he literally dropped the weight through a 3' circle from 100'! Right now, the forecast is pretty much rain for

Re: Storm Damage
Having been to Hara Arena a number of times in the early 2000's I was amazed to see the damage tornadoes can bring. I never knew Dayton was in the 'danger' area.? WE don't get many Tornadoes in VK,

Re: Storm Damage
Having been to Hara Arena five times in the early 2000's it was quite a shock to see the damage there.

Storm Damage
All: Well, once again I got nailed by the storm that hit Dayton (I'm about 50 miles south). This is the third time in as many years that I've lost my antenna. The culprit: a limb from a big old

Re: JackAl User Manual BOM page 26
That was corrected a while back, but our web site is down because it was hacked. Al's going to tear it down and start from scratch this week. Our ISP has been virtually no help at all. Jack, W8TEE

Jack, FYI, In the BOM at the end of the manual, the 5v 1.5A voltage regulator is labeled LM7812CT/NOPB-ND (Digikey) the number is for a 12v 1A regulator. The actual part is LM7805CV TO-220 which is a

Morse Tutor BOM Error number
Doug pointed out that I have the wrong encoder number in the BOM for the Morse Code Tutor presented at FDIM. You definitely want the switch and the PEC11R-4020K-S0024 should do fine. Jack, W8TEE
