With respect to the lamp oscillator the frequency is not that particular. Not sure you need to adjust it if the lamp ignites. Think they are in the 137 MHz region. Good luck Paul WB8TSL On Fri, Feb 11, 2022 at 1:31 AM Julien Goodwin wrote: > > > On 6/2/22 1:14 am, Matthias Welwarsky wrote: > > O

Hi The various “sub species” of 10811’s were a test and select item done on the HP line. When they found enough to fill the need for this or that part number they stopped testing. Some of the normal parts could indeed be better than the selected versions. We are now a *long* way past when this s

I did something similar for the ESP8266 -- this is part of the nodemcu-firmware project. I did actually implement the clock model to slew the clock rather than insert discontinuities. I did not figure out the promiscuous mode trick!! Performance is limited by the wifi stack and the asymmetry intro
