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!

This store demands women to lock their purses in their vehicles, or use the store's lockers during your shopping 'experience'.
They follow you and confront you if you just walk in and have your bags, or your purse.
INSANE fear, paranoia over theft, so they confront you and demand you comply with their ideals. They consider EVERY CUSTOMER as a potential THIEF!
Theg also do NOT ALLOW WEAPONS OF ANY KIND!
GUN OWNERS ARE NOT WELCOME!
Any store that acts this way, must NEVER PROFIT FROM CUSTOMER PATRONAGE!
IF THEY CONSIDER THEIR CUSTOMERS AS THIEVES, HOW CAN THEY DESERVE OUR PATRONAGE?
BOYCOTT THIS STORE BY ALL MEANS!
The store is off Signal Butte and Apache Trail.

Dig deep into this cult, you will see the Clesrwater, Florida police are co-conspirators in covering up for crimes committed against people that are 'enemies' of this violent cult!
From Germany, to America, the cult controls people, their families, and also has their hands oin police departmets to cover up criminal acts committed by members.
This cult has a growing hayred by ex members, and for good reason.
People across the globe are dying, and nothing has been done to convict the person or people responsible!
WHY DO WE ALOW TERRORIST CULTS LIKE SCIENTOLOGY, TO EXIST AND FLOURISH SO OPENLY, AND NEVER BE PROSECUTED AS A FRONT FOR TERRORISM, ESPECIALLY BY THEIR 'MEMBERS', OR BY THEIR LEADERSHIP, RUN BY THE HEAD CRIMINAL TERRORIST, DAVID MISCAVIDGE?
