Hello dear OM Andrew, I humbly disagree with your opinion above. Out of my point of view, the LPFmodule for the highest frequency should go into the slot closest to the PA. Related to the numbering

Well I suppose I am on the other side of this conversation. I did find it funny. When I read this I thought of my 3 kids not necessarily all kids. No way would they want to wind toroids and I can

60¢ per toroid and a tool to the end user IS good. +1

This afternoon for your reading pleasure bring you "7.1 - Release of the Magic smoke" A couple weeks ago went to do alignment and fuse on ps I used blew. Set all side. Yesterday thought about

I really meant no offense by it can we just drop it! 73s Rick, W2JAZ -- 73 Rick, W2JAZ

Tempting. Not too bad a price for prime toroids, too. Jim

Hi, Paul Here are my guesses: (1) R65 is mis-marked, actually 0.3 ohms. Or the topside wire is touching something. (2) There is a wire scrap wedged underneath R47 (3) There is a wire scrap wedged

I'm with Arv and Colin as well. I don't see what's funny about kids learning to wind toroids and bring introduced to ham radio. The abundance of small affordable kits these days could help rekindle

Well, I was blessed(?) with four aunts and some of them decided to teach me cork knitting so they could get on with watching soap operas in peace. It is not a million miles away from

I'm with Arv, I don't see what's funny. Getting kids involved with making toroids is a good idea. Winding a toroid is a fulfilling process, you can see instantly whether you've done a good job or

Introducing kids to ham radio is a great idea, but the thought of them winding toroids I found funny. -- 73 Rick, W2JAZ

Thanks Andy, will have a look for it. I seem to vaguely remember seeing the thread some time ago. Hi Jakob, I'm getting about 0.5w on 20m and about 1w on 30m. Thanks for the help guys. Dave, G8PGO

Hi Dave, as its 20m your problem is most likely to be the caps on the lpf board, search the forum and you'll find several references to it. I can't remember which ones off the top of my head but it's

Hi Power measured on a U3S running at 5V on the PA at 20M bilfler wound, using R &S NRPS8: and Just under 7.5V PTP on the scope (7.375V) nothing wrong with scopes! 73 Andrew G8UUG

Ok, then that explains my concern when I saw one oscillator value of 27,004. So I wont change anything and judging from my recent QSO there was no mention of being off freq. Thanks

This drift in power output is most likely a thermal effect. The BS170 changes its offset voltage in function of the junction temperature. See https://www.onsemi.com/pub/Collateral/BS170-D.PDF You may

Jim, I didn't have time to do any of the things, last night, that you proposed but will start trying those later today. I'll anxious to see those results and will report back. 73's. John / K7RLD

Paul, I cannot see this being anything other than a short to ground. The track from the slider of R47 is very thin, it goes close to pin 1 of the LCD, maybe a solder whisker there? Get a powerful

Arv, you may find the answer reading Ricks first post explaing why he is looking for prewound posts. Martin DK3UW
