Noise? active antenna for 200 Kc to 200 MHz

Ina MMIC (10) just arrived, let the fun begin ;)

How do you make your boards?

Back when, I worked for a defense contractor. They would test their conformal coat process on double-sided 3x6 copper boards, then they would toss them into the trash.

I have a lot of 3x6 copper boards! haha

Most of these projects are done the "manhattan" way, unetched copper boards which i buy in bulk of different sizes, thickness single/double copper coated and small islands made for the parts that need to be connected, rest is mass or -.
Small rail etched for the + done.

Larger and projects that need a pcb done for me at the ham club, they hav all the stuff there, no need to play around with etching fluid here and get stuff ruined ( Don't ask) ;)

The pieces of unetched pcb are also nice to make project boxes, using ,my 100 watt soldering iron to solder them together easily workable on and keeping the plain side without copper to the outside a can of acrylic automotive paint does the rest.

Here's a pic of one before I use it. The board in the holder is the one for this project. The one in the foreground is an HV supply board for a tube-type audio amp I'm building my step-son.

Hmm, please elaborate.

I am yet (fingers crossed) to destroy anything (other than the copper board).

As i wrote, don't ask, ruined a perfect whitewashed wall spilling the stuff, clothes ( falling apart a week after the ferrichloride had it's way) and a now ex wife upset like hell.
Took some good work to get that wall white again...;) meh......sh*t happens.
Dang little creeps those ina 02186 thingamabobs.... don't sneeze with one unsoldered on the pcb... ( also don't ask, found it back though...)

Goodness; it's a wonder I've not destroyed some wood flooring or carpet yet myself.

Now that kind of stuff, I have done numerous times. The worst thing is iPhone screws when I'm replacing displays on those dreadful things. I've lost a many of them.

I started dabbling in electronics at the ripe age of 12 years old, tubes big large components and 20/20 vision, now I'm 61 and fall back to itty nitty smd stuff, thought it should be the other way around.....;)
Steady hand, standard soldering iron i did lots of work with smd though, building Ga-As fet amps for 2/70/23, lots of modding the FT 847, and some work on the FT 100, including adding the AM filter.
I liked the rebuild of the Heathkit SB-1000 more ;)

Will make picccie later of the "enourmous" amplifier board.... postage stamp size...

Build the print added the teflon and ferrite stuff.

I'm a sh&t photgrapher, but you get the idea.
Pcb has been drilled through at 10 places and a wire is now connecting upper and lower copperlayers.

B.t.w. i found that nail polish (looking at that bottle in your piccies) is a good preserver of outdoor prints, just get the stuff all over it let it dry and no moist will get to the components or pcb.
Larger pcb's i spray just like my alu antenna's with clear coat tectyl ment for protecting chrome ( bumpers) in winter.
Colorless just like lacquer but much more resilliant outside.
