Ge Charles I don’t think so. We just blended them into the manual. 72 Johnny -- Check out the 4SQRP website at 4sqrp.com

I don't know anything about the QRP Labs ' ProgRock rig...not even knowledgeable about QRP Labs. Is their website qrplabs,com or something like that? I will try to go check them out. EuGene, KA5NLY

Are there any changes from Dave(Benson)'s original calculations? 72, Chas - NK8O

Good afternoon I am pleased to announce that our kit Group for the Hilltoppers has packaged up a 30 meter version. We previously only kitted them by special request. The link for the info is found

I would bet there was volumes of scientific evidence to support that claim ;) What it would do is increase the mass the element would need to heat. I'm not sure about the premature failure, but it

Thanks, Johnny. I was thinking about buying a dead one that is listed on FleaBag (aka, eBay), but it sounds like it would be very difficult to work on it, and likely more trouble than it's worth. I

Hello Eugene I can shed a little light on the subject. It was a 17 meter transceiver that was put out many years ago by the 4 state group. It was redesigned for SMT parts and is currently in holding

I have been trying to google and otherwise track down information on the Ozark 17 meter QRP transceiver with no luck. I am seeking a copy of the manual, schematic, and other info, including assembly

Well, Interesting concept. That was 50 years ago. A modern temperature controlled solder pencil will just crank more power into the heating element to maintain temperature. So you won’t gain any

Ron, Thanks for the two posts. Woke up this morning and wondered if I had the BOM as a separate document as it is not in my copy of the manual. Funny how I think better after a good night’s

Here’s what is in the BOM - 0.5” OD x 0.75” 10-32 Nylon Spacer 72 - Ron - AG1P 4SQRP Volunteer Webmaster

I remember an old trick reported in Popular Electronics in the earlier 1960s. The author would wrap some 14 gauge bare copper wire closely and tightly around the outside porcelain part of of the

If you have any doubts email the designer NM0S for help. I treasure my own Cyclone, best simple rig in my experience. 73 curt

Looks very much like a 1/4" nylon standoff John K5MO

I'm building s/n 201 and do not have the coil form. What is the diameter as I will have to fabricate one here. Thanks for all your help -- 72, Clark WU4B

Actually it's more of a problem trying to use too cool of a temp. Strange, but it will heat the circuit more while trying to 'melt solder'.

Woody, soldering is part art and part science, but like painting a car, the result is a matter of how well you prep the surface, keep your tools in good working order, and use the right tools. Lead

Hi Woody, My el cheapo made in China soldering station I picked up at the 2013 Dayton Hamvention doesn't have a temperature scale, only one with colors so I'm not exactly sure of

THANKS! to all for great info. in response to my soldering questions. Here and off list. ALL very helpful. I am now waaay more knowledgable and inspired. I'm grateful to all of you for your time
