Hmmmm Once I find a schematic on the internet or some publication, it's fair game for me to replicate it in whole or part.? Period.? Take a look at my QRZ page and see all those stolen designs!?

This is the W7ZOI article Walt mentioned showing the new emitter resistor value. I too needed to change mine to the new 3.3 kohm emitter resistor. https://w7zoi.net/filters/9megxfils.pdf 73, Steve

Thanks Walt. I'll give that a try and see what happens. I still have that small batch of crystals on my bench. 73 Mike M. KU4QO <wt3i14297@...> wrote:

Jerry, Chuck wants to get permission because the SST-20 is copyrighted - the radio design - manual - schematic. So, out of respect for Wayne - both were originally part of NorCal Club. So, whatever

Hello gang, I was talking to a mentor (Elmer) that I have been talked to many times in the past.? Well, there are many Elmers on this group because this group is a goldmine of great projects and

Alan - I also built Jim's Manhattan Islander amp. I built it specifically to fit inside my Fort Tuthill 80, as that rig will only drive headphones. Unfortunately, I wasn't getting good fidelity from

Howard - that 2N2 group is intended mainly for discussion of the Norcal 2N2/XX kit. It would be great if there was a discussion group for 2N2 scratch builds but that doesn't seem to be the case. I

By the way, there is a 2N2 discussion group on Groups.IO.? I posted a question regarding modification of a 600:600 transformer for use in the 2N2 output section.? I no longer need one but others

G3URR crystal measurement method Mike, In one of his more recent postings to his website (~last two or three years), W7ZOI changed the oscillator's emitter resistor from 1K to 3k3 to reduce drive to

Is there a website to look up rules, etc.? I have a sasquatch number.. if I can find it..? hi hi.. 73, Gary WB6OGD

Hopefully, people do not mind me posting the link to our wiki page yet again.? Feel free to add more links. Sources of QRP Homebrew Supplies /g/qrptech/wiki/23197S (

Thanks Gary, i’ll be listening for you. ?Good luck. Wayne

Speaking of crystal measurements, I got highly involved in that some years ago and now I'll toot my own horn a bit with this link to a presentation I did on the subject at OzarkCon.

Look what turned up in the "Magnetics" box! Howard, n3fel

Timely post for me... I haven't done a manhattan style build in a while and thinking that it was time to do another, decided three or four weeks ago to build the soldersmoke 40M DC receiver. I thought
