This station chief has always had a huge collection of measuring equipment and has been very active. He is planning to focus on amateur radio from now on, so we are posting him provisionally. I'm looking forward to seeing when he will speak.

I can't check the radio, but I think it's in a different room from the operating room.

You're making something amazing. 150M means 50MHz/144MHz can also output 0.2W. Connect it to a high-power linear amplifier and emit radio waves quickly. By the way, please introduce us to your favorite linear amplifier. If you have an unnecessary amplifier, please contact us and we'll come to you.

It is said that the group delay is bad, but I would like to see the curve of the entire passband. I can see the shape factor, but I don't know the in-band ripple. I would like a little more data between each band.
