Sleeping like a baby!

Angelina was a perfect guest, sleeping on the bed.
She was never trained, and peed on my jeans.
No house training, until now. We will get her into a routine, and surprise...she used the pads in the bathroom, and then lost in the hallway...the training continues!
She will be assimilated!
RESISTANCE, IS FUTILE!

Our rescue pit!
She was found by my wife, wandering, and was known to be at the gas station all the time. The same place my wife found her.
She is really sweet and gentle, but might have a hip problem aa she favors her right hip. She was dehydrated, and starved. Sick people that mistreat animals need to be shot!
She lives with us, and she was super wore out. She laid down and drifted off to sleep.
Her name is now Angelina, and she truly is, an angel.
So loving and affectionate!
She is a keeper!
Bath time next...give her the care she so desperately needs.
She will get all the love she can handle.
I am happy she is here, she needs us, and we want her.
So far, she appears to approve!
Sleep well, angel dog, you deserve it.

Initial testing begins. System configuration, component selection. All interconnecting cales are low loss RG142 double shielding.
IM panel is a dB products dual isolator and harmonic filter.
RX has a single notch cavity which actually notches the transmitter by no less than 30dB. The receiver does not even hear a peep!
Tested at 50 Watts, this runs a cool 18 Watts.
GaAs FET preamp hears well, and cleans up noisy input levels. No problems running a full day so far.
A good morning project.
More will be built, both amateur, and commercial.

Kenwood, TK-2170, VHF.
So many problems for a radio less than a year old!
All antenna switching diodes exhibited high loss, then Q705 died, and went open.
Next, the filters began to go bad, showing signs of lpss of skirt response, dynamic range. Then XF401 (49.95 MHz) MCF, had poor frequency response, and showed a lot of harmonics. The receiver is still deaf, requiring -8fBm input to activate. I believe a resistor or chipn cap opened, or shorted.
Sending this one in. No sense digging into this, as it requires more repair than I can afford to give it.

I love testing with properly calibrated test equipment.
Measurements are far simpler when you can trust your readings.

You stand as one, and tell the cop that if they arrest her, they will bring down a shit storm of hell for employee abuse and criminal usurpation, and any that try, will have force used to stop them!

This has become a labor of love, getting the different stages working properly, and adjusting levels between stages, and also final stage levels testing.
The generate function was requiring a lot of alignment, as the spec-an display was failing to properly indicate center frequency, as well as known signals of a known level (in dBm).
The receiver was really stone deaf, so I had to align the high freq. Multiplier/oscillator module, the generate amplifier and VCO gain. There are a lot more alignments needed, but the receiver now detects a -89dBm carrier, and audio can be demodulated and understood.
Service monitors are generally not known for having sensitive receivers, and certainly, this one is no different!
BUT: I can now clearly HEAR EVERYTHING directly off-air without a preamp at the antenna port!
Of course, signals below the receiver threshold, can not be monitored.
I enjoy listening to WWVat 5 MHz, and also at 10 MHz. This is a feat I was unable to enjoy prior to base alignment.
Local repeaters can clearly be heard, as well as direct comms not using these, such as 446, 146.52, and MURS/GMRS frequencies.
All in all, a handy test instrumet that fits on s seat so I can monitor RF signals, audio levels and quality, and if I turn off the CRT, I do not need to worry about being parked with the engine off and draining my battery.
The internal battery died long ago, but it may be rebuilt.....some day, perhaps, but not today.
Next project: R2001D/HS receiver assembly!

LIVE LONG AND PROSPER...
SPOCK....OUT!
