Hey John,
I see the photos now.? Very nice.? ?I think your power meter says 398 ?? As in 398 milliWatts?? Hard to tell.
And I see the harmonics showing in your TinySA spectrum analyzer.?
Going forward, I like to put my projects in strong cases.
Jameco aluminum enclosure for US$8.? However, not sure if this is the same size I show in my photo or not.? I originally got this case for my QCX that I have not finished.? So, plan on buying more of these enclosures.
Here, I put the Sea Sprite+ including its can in a case from Jameco.? However, I was only trying to see if it would fit.? I like my cases to be a little bigger than I need to give me room to work around.? I broke pots off the pcb of a MFJ Cub I built because I kept taking the board out of the case and putting it back in.? I kept trying to re-align the radio to get the best performance...? ?Or I wanted to show another ham its internals.? ?Anyways, and I had QRPme kits in the past where parts or modules got lost or pcb got damaged.? So, I like to put my stuff in metal enclosures now to protect them and so I will not lose parts like finals and crystals and band modules.? Plus, protect it from dust. I think the only radios you would not put in a metal enclosure are crystal radios and regens and AM radios where the bar antenna is in the box with no external antenna.
I will have to drill holes to put the off board connectors for power, antenna, phones, and key.? But to me, that is no big deal.? It is putting variable capacitors, LCD displays, pots, etc... into the case is when it gets hard.? But the sea sprite does not have those things - so no worries.? Yet, I probably - if i knew where to connect it - wire up a cheap frequency counter LCD display you can find on Amazon or ebay these days.? Then again, the radio is rock bound (crystal is 7110), so no point in a frequency counter?
I used a similar case from Jameco for my homebrew z-match for QRP radios.
Question, any recommendation for screwing the sea sprite+ pcb and can to the case?? Maybe drill a hole in the case?
