Earliest example of Manhattan construction?
Looking through my library, this is the earliest example of using PCB

Re: 2N2/20 Scratch-Build - Progress So Far
Hi Dave
I note there is a slight difference between this circuit and the K8IQY circuit which has a 56 Ohm resistor across the secondary. Might be worth a try.

Dave,
I doubt that lightning strikes twice but just maybe...

Re: Tayda Electronics and parts, heatsinks, Octopus
FWIW, I've ordered from them probably around 8 or 10 times over the past 10 years or so and most, if not all of the packages came from within the US. Don't quote me on this, but Colorado springs to

My oders have shipped from the US, and quickly..? maybe depends on what you order.
Quality has been ok, only the cheap headphone jacks have been flaky.

Re: Tayda Electronics and parts, heatsinks, Octopus
That could be, but every order of mine (10-12) has, and always has, shipped from Thailand.
I'd love the USA warehouse to be the one, but for the past 6 years, all Thailand, FWIW.

Re: Tayda Electronics and parts, heatsinks, Octopus
Hi Daniel -
Like many of us, I'm often on the lookout for good deals on parts, and even not so great deals if it's a much sought-after part that is hard to find. However, I'm beginning to question

Re: Tayda Electronics and parts, heatsinks, Octopus
Not according to their FAQ.
Where do you ship from? Depend on item availability and customer/recipient location, your order will be shipped from one of these locations, Singapore, Thailand and

Re: AA7EE QSO and SolderSmoke DC Receiver
Chuck - that looks great, and the layout closely mimicking the schematic makes it very easy to follow the signal flow.
It was great to work you. You're making good progress with your 17M WAS. I have

Re: Tayda Electronics and parts, heatsinks, Octopus
I have had constantly good luck buying parts from Tayda, but they do not have a USA warehouse. All from Thailand via Hong Kong.
Great company. Not sure how tariffs will affect them, so I just received

Re: Help aligning VFO (Ozark Patrol regen)
I've observed the same thing. The ability to do accurate L & C measurements
can make trimmers unnecessary. Also, when you're close but not exactly
there, you can use LTspice or other simulation

Excellent sentiments all the way around! That I stocked up on kits, pcb material, parts and stuff before I retired BEFORE I RETIRED is kinda gladdening.
