Here is some information on how to get a Bullseye LNB apart, how to modify it to use an external frequency reference, and how to fix it if you wreck it doing that modification. :-)

Very helpful information. Just found your channel, and I will be back for some more videos.

I'm glad you found it helpful and thanks for letting me know. I always hope some part of what I cover will be of use to someone.

Great job. I didn't have any issues hearing you on the voice overs. The audio is a little low on all of it, but no big deal. I really enjoyed you going through this to the extent that you have. Those 0402 and 0603 parts can be tricky. I haven't been brave enough to attempt fooling with 0201 parts. I like the larger smds as most probably do. Thanks again for doing such a thorough job. 73's.

I should have tried to measure the size of those parts. They are a LOT smaller than the 0805 parts I used in the beacon project. I suspect the smaller ones are 0402. I've had to adjust the audio a bit low on all of my videos, otherwise voice peaks clip and distort. I guess my speaking is too dynamic. I tried forcing myself to speak with consistent loudness. Didn't work. Those voiceovers really sound muffled or compressed to me. I will try a different microphone soon. I used a different camera this time for the video segments. Audio on it was not as good as on the camera I had been using, but the camera part is much easier to work with. I have as much to learn about making videos as I do 10 GHz!

@@n1bug Again no big deal on the audio. I was able to clearly understand you so I wouldn't worry to much about it. Sometimes things like the room that the videos are filmed in can even be a factor on some people's videos. Excellent content none the less.

Also in use in Europe for QO-100 receive. Great little things.

I wish I was in the footprint of QO-100. Would be interesting to try that.

If the TCXO is to become a throw away, heat the metal top with a blob of solder and it should pop off without collateral damage.

I tried that with one of them but my 70 watt soldering station was not able to get the job done. I tried using a big tip, flux, etc. but it just didn't heat the solder under the pads enough.

For future reference and to use proper terminology in future videos, these devices are not LNBs. LNBs are a portion of the feedhorn assembly. It is the electrical component that attaches to a feed horn waveguide. A LNBF (F indicates Low Noise Block amplifier with an intergrated Feedhorn). I enjoy your experimentation, as I have been designing, manufacturing and distributing in the satellite industry for many years and recently got back into amateur radio. 73 AI6US

Your point is well taken. Unfortunately this is a confusing situation. If I refer to them as LNBFs then I am using different terminology than the manufacturers and vendors, who label and sell them as LNBs. That would tend to create confusion for my viewers. I should have mentioned that LNB is technically incorrect despite common usage.

Apparently the colloquial terminology is changing, now that they are integrated.
