These do require a good amount of power, magnetic coils, etc, but provide stable and rather low noise output, and good modulation capability. With a little investigating, it wasn’t very difficult to determine the approximate specs for the module I purchased.
Current consumption on the 15 V rail is normal. Hope to trace the defect to some specific part. Voltage at the resistors avanrek about 4.
The analyzer allowed me to see the frequency move around as I changed the current on the tuning port. It matches the first pinout in this old spec sheet. This site uses Akismet to reduce spam.

Note the hand made labels which may explain the cost of these units if purchased new… looks like US style handwriting to me.

A range of 6 dB matches the units on the spec sheet, but a 7 dBm minimum power is below that of any of the comparable modules.
Well, seems that fixing this is beyond what I can do here with the tools at hand.
To look inside, carefully removed the top weld seam on a lathe, and the you can pry the case open. This makes the module’s tuning behavior more like the next lower range, for example the AV Before verifying the suspected power level, I used an inline attenuator to avoid any chance of damaging the machine.

SimonsDialogs — A wild collection of random thoughts, observations and learnings. Your email address will not be published. Next, I measured the coil resistances. Notify me of follow-up comments by email. With mA flowing, a signal finally popped up at around 7. To determine the likely power output, I hooked the oscillator into a dummy load, then measured the current draw on the 15V input — it was almost exactly mA, which means it is probably a 30 mW The lower edge of the specified range 7.
Knocking it with a small! The closest standard units appear to be yi AV through AV, which cover 8 to With the specs determined, I now have enough information to continue work on my project using this oscillator.
Varying the coil current — no effect. Also avantei other parts of the circuit, with a thin wire, under the microscope. Satisfied that the module would behave somewhat as expected, I hooked it up to a spectrum analyzer. Save my name, email, and website in this browser for the next time I comment.
