Curve Tracer ASA HW-210K review

This review is designed to help you figure out how to use the curve tester that did not come with any instruction or power supply. Note that when calibrating the tester set the scope to 1V per graticule. Sorry I forgot to mention that. This device will not work at 11V and it barely works at 12V. It will work at any voltage above that and up to 24V. However, the output voltage will rise with the input voltage and that makes the calibration different. It should have had a voltage regulator on board to prevent that. Other than that, it seems to work OK. No overheated parts or any other adverse effects that I can find.

You can wind your own 2.7mh chokes for KV4JT type solid state conversion projects. In order to solder the #40 wire I use a piece of sandpaper to remove the enamel (very carefully). I have not found a chemical that will dissolve the enamel. It is hard to sand without breaking the wire. Some types of wire have a low melt type of enamel that will allow you to solder it directly without any sanding...

How to convert a R392 military radio to 100% solid state. The reason so much of this video is devoted to making plug-in modules is because you can't convert the radio to SS without some method of making modules. There are other methods of making them. In the next video we will show you more of the workings of the radio and how to make PC board types with SMD mounted parts that look more profess...

Tube Test Socket Extension 7,8,9 pin

How to make homemade tube test socket extensions for 7, 8 and 9 pin sockets using readily available materials. Note that the 9 pin variety may not have a metal center post. You can make a small ring of #18 wire to fit where the #10 wire protrudes at the center and use it as a washer to solder to. I forgot to show that in the video.

SHURE M68FCA hum

Переглядів 2,1 тис.4 роки тому

The Shure M68 series microphone mixers have inherent hum caused by the presence of a small power transformer. You can run the mixer off of 24 to 28V DC and eliminate the hum. The M68FCA has no jack on the rear for a DC connection so you have to make one.

R390A Solid State Conversion - video no. 1 There are a lot of details to show in this conversion project. I will make future videos showing more details. Sorry, I forgot to demonstrate SSB but it works perfectly well. I'll do it in the next one. Since the video was made I have corrected the AVC overload on strong AM signals and the Noise Limiter now works. The balanced line audio output is stil...
