Curt, Missed this one... I'm still confused by those FLxx markings, The board was revised but I didn't get the v2 board or artwork. The v2 manual v1 board was patched to look like the v2. I

Here is picture of N5ESE Altoobs.? Of course it uses some conventional tubes at 150V B+ for 2W output Curt KB5JO

Curt et All, The article is on pages 20/21 of the May 2006 magazine. I don't have that issue on hand but I'm a subscriber so probably can get it if anyone is interested. It's a pentode in a Pierce

Rex, Here's what those tubes were for... Attached is the circuit of the 12AL8 I built as a potential kit for the 2017 BuildAthon. It works but very little RF output. Chuck, W5USJ (ex K2OFN) ARCI

Gangue, I can't keep every kit on the New Stuff links or even the HOT Links sections forever as it will just get as long as the index to ALL my kits. I just printed the entire list out last night and

Sprite Band Pass filter question for Chuck: My Sprite has an output BPF labeled "V2", FL3 n FL7 are 1200 pF; FL2 and 6 are missing; FL1 and 8 0.39uH 11t 37-6 core.? "Default" has FL2 n FL6 = 1000

Curt, it's all your fault, I'm blaming you! I just placed an order for a Sea Sprite. I should get the Lil' Squall going in the mean time until the Sprite turns up. 73, Colin

Like the Sea Sprite because of the more open layout than the Lil Squall.? I have no BCI with either of them.? Installed a trimmer in place of the 22pF xcl so can tune around about 3 kHz.? Bought

To me, the Sea Sprite was a better kit.? That was my first attempt to use a band-pass filter for the front end.? Mostly to minimize the BCI rather than use a high pass filter. It seemed to work but

I had forgotten about the Sea Sprite, the kit is not easy to find on the QRPme website, it seems that you can only find it on the long list on the left hand side. I tend to use the filters to get to

The Kantronics Rockhound is a neat little simple rig. I used one with a Hammarlund HQ170 while in college...and I had a blast. The combo was quite good, even with only a 7040 and 7112

No more fun than that..can't wait to get back to my bench.? On Mon, May 25, 2020 at 10:57 AM, Chuck Carpenter<w5usj@...> wrote: I've been working on a project using hollow-state

Finally two QSOs on 40M with the Sprite putting out 400 mW into a 40M Loop.? Both QSOs with stations in TX, 135 and 250 miles away.? Received 559 from both of them until the QSB interrupted.?

Good job Chuck! Curt KB5JO

I've been working on a project using hollow-state technology mixed with modern building a dual triode 1935 Jones Style transmitter. I hooked up one of the two, using a 12AU7, in the setup shown. A

My search for this failed, appreciate link if possible.? Had heard of the SP-1 and the Rockhound but never saw one. By time got involved with QRP,? transceivers were more the norm. Since

On good days, in Northern Illinois, 40 had a Band of 250-330 miles out. Lately, it is very very long. I must say I'm surprised there isn't more Sea Sprites out there. I need something on 30, so I

My education has been lacking! I had never heard of an MFJ-40T, but doing a search and there it is. Evidently highly thought of, it predates my venture into QRP beginning 2005 when retired from

I'll have to fire up my vintage MFJ 40T transmitter and hunt around that area. [email protected]> wrote:
