Guy, I have an LZ1AQ that almost got installed before I had other things happen in life. I am also laying out a Wellbrook board from the traced-out schematics. My main antenna has been an active whip

I took introduction to chemistry and physics in the 9th grade (along with Latin and typing) The teacher was a cast iron !@$% about properly documenting every step of every experiment we

Steve, ?? thanks. Well, I am interested also in VLF, so maybe I should try to get hold of some 2SK932, though the idea of working with SMDs is not appealing (but I have already done that in the

Hi WN4ISX and Simon, Thanks for the notes. Both of you. First WN4ISX (Terry?) Thanks for the reminder to keep notes. Being an old submariner and Sonar tech, ELF,VLF,HF and NDB's and CW interest me.

PS.. I am new to using receivers, and SWL CW listening. Newbie here. Not new to Ham Radio QRP and CW though.. -- 73/ Guy, N1GMM Web Presence: Withywindle ( https://niggles-parish.blogspot.com/

Hi Mike, Thanks for the info on Chris's paper (Chris, thanks for all the work!). Very interesting and am thinking of implementing a shielded loop radial using this. What loops are you using? My

It is an incredibly long tale told across multiple mailing lists, mostly forgotten. Anyone remember Onelist? Loads more transferred and absorbed. I'm awaiting more radiation, sadly their machine

Also wanted to mention that I'd probably go with PEC-AL-PEC 1" if I had to purchase loop material again. Like this one: https://www.ebay.com/itm/144928782978 You get slightly more than 1" (OD) of

I had a complete replacement of both knees simultaneously a few years ago. I didn't want to go through PT twice and wanted it over with (the pain on simply walking had become intolerable). Sure, it

Not sure if this info will be helpful to anyone but I double boxed my LZ1AQ. Internal box is what it came in from Chavdar. An external one is much bigger IP67 box that also holds two 1m

Carl, You can try QRZ, N4CY, or Everettsharp (at) aol com. Everett N4CY

I second that. There is a SprintLayout group on Groups.io. Lots of useful files in the files section. The program costs about the same as dinner for 4-5 at McDonalds and is not a subscription or an

Sometime back I mentioned to the list about experiments I've done using various numbers of jfets as well as trying different types. Using the 2SK715s (or the SMD equivalents), the input impedance

Everett, How do I contact you off-list about some board designs? Thanks, Carl AK4OT

What happens if, instead of the 4+4 2SK715 FETs used in the schematic of the ALA1530, I will use only 2 + 2 ? I have only 5 of those FETs, so cannot build the schematic in its original form... Are

Yep. I'm a moderator here, mainly vetting new member's first posts to make sure they're on topic. Having moderators spread around the globe helps get posts up while others are curled up in bed sound

Terry, you don't need to jump in right away.? Owners and Moderators can be inactive if they need to.? Take care of yourself first! Chances are that Steve set the group up with a handful of other

Another thought, initially I installed my loops with the bottom of the loop at 10 feet. I removed them to stabilize the support pillar before a nasty thunderstorm with high winds was forecast and?

Thanks to everyone for the advice, name here is Terry. I'll read the linked articles after preadmission testing later today. It is a bit of a zoo here right now.

Also, I need to mention there are the Manuals. Getting Started manual - /helpcenter/gettingstarted Members Manual - /helpcenter/membersmanual Owners Manual -
