Installing 'man down' switches in new Kenwood TK-290 highband portables.
Cimarron ANI encoders are also being installed in conjunction with the switch.
The switch will activate an emergency alarm transmission if the radio is left horizontal for a predetermined length of time.

Yupiteru receiver 'project-from-hell.
ONE filter acquired....
One more required, 'IF' I can obtain it.
Once inststalled, I can then test the sensitivity.

This is WHY RG8-X should NOT be used on anything above 50 mHz.
Notice the loose braid weave.
Not good for IMD or RFI.
Very poor shielding!

I thought braid had just gone out of fashion these days ........

What I did today..
Pic#1, what I repaired, pic#2, how many I repaired, and pic #3 is the remainder of what needs to be finished tomorrow. Pic #4 are batteries I need to analyze for proper capacity, or replace them.

+Daniele Paolo Scarpazza I have three actually, but all have control flex problems, but I caused one by being impatient. My favorite UHF radio just got a shiny new yellow case, and I pulled a 'wee bit' too hard on the assy. when removing it from the old case....BIG mistake...<):-€

You think you've got it bad?
Please note where THIS radio has been, and why I REFUSE to work on it!
A damn biological nightmare!

Yeah they're also aggressive, stingy and sometimes lethal.

Diatomaceous earth FTW.

Service monitor calibration day!
IFR1200S(mine), IFR 1100 S, MOT. R2001D/HS.
Freq. error, deviation, mixers, Lo, TCXO, scope, triggers, display alignment, and a whole lot more!
One unit requires almost a full day to align everything!

HT750 That was shown previously.
Side buttons replaced, used front cover with original flex assy. And it looks 'almost' used.

Those buttons can be a PITA or at least the ones on phones are at times lol.

I have FILTERS!
All I need to do, is solder one of them in. I am expecting more, so this is actually the beginning of the final process.
I just hope the frequency response, stop band attenuation, and usable bandwidth will be adequate.

Good thing I have their current data sheets. I think this pair are the narrow band (6.25/12.5) kHz. versions, but I will research them to be certain

I wish Circle-M would have pushed software updates to both versions of the Moto-G, but NOOO, we are going to be stranded with 4.4.4 forever.
I think I am going to stop buying Motorola, and move to Samsung, or HTC.

I know...I was picking nits. Way too bored and upset right now. I should return to Wisconsin, at least the people aren't so wrapped up in themselves there, like they are here!

Baofeng, UV-82.
Simple, single board radio..
The thing I am not impressed with, is the P.A device.
An SOT that really should be used as a driver stage.
The heat sinking is accomplished using a blue, heat conducting silicone pad. It is quite thick, and it looks more like an insulator than a heat sink/spreader.
I believe they would be ahead of the curve to utilize an actual heat spreader of copper, or aluminum at the very least..
No wonder I rarely ever go above the 1 watt setting!
I also set the frequency error to under 100 Hz. I can't stand seeing a VCO running 300 Hz or greater frequency error. No wonder some radios sound crappy.
Also, if there is not enough drive to the VCO, you can get sensitivity issues, loss of dynamic range, and general loss of receiver performance.
