Spice and other programs and manual calculations may be exact, but components are not. Reminds me of when I was in college and doing labs. The school had boxes that had components on bread boards. We

Bo, Spice may say one winner but your model is wrong. The issues Too low FT, 3904 has ft of 300mhz,? some seemed less so. HFE that depresses at higher currents.? Spice models are not valid for that

One more comment. I only looked at the output level at 21Mhz with an AC sweep. Enjoying all the comments on other's REAL experiences. As a college prof we stayed in the audio range all the time in the

One update. This SPICE models aren't exact.? A ?transistor beta may be listed as 100-300. ?Not the single value in the SPICE model. Long ago I built a fantastic heathkit MOSFET receiver, used

Jeff, Also check the emitter of Q90 to see if a .01uf or a 470pf or 220PF is there. There was a change to lower the value from .01 to 470 pf to level the output power so 80M wasn't 15-20W when 20m is

Thanks for jumping in Tom.? Yes as I noted above the bias resistors are adjusted for maximum output.? I felt pretty good about 8 watts on 20 but not too happy with the 4 on 40m.? :(.? Any other

Hello Arv Good idea. I like - groups.io/g/hamtest But I can not be a moderator because I'm not a technician just a handyman radio amateur. I am continuing to work on the realization of the spectrum

Bob: Your first reason is sufficient enough not to use the TFT. I was just curious. Jack, W8TEE

Graham, it's difficult to tell you what may be going on based on your description. You may be hearing digital birdies as a result of not twisting and poorly routing your wiring.? The audio cables

I placed the TFT file on my desktop.? Then when the OS assigned the Nextion a drive letter I just copied the TFT from the desktop and pasted it to the Nextion.? I did not use Nextion Editor. Vince,

How about:?*Test Equipment and Measurement* as a name for a new group?? I had proposed this for the eHAM site in the past and would be glad to be a moderator for the group. My own complement of test
