How fast is a PIN diode?  How fast is a 1N4007 in an Alpha 87? If you have not measured their speed, how can you make that statement?

  It is my understanding that the 1N4007 (only) IS a PIN diode and I have
used them to replace PIN diodes in relay-less 2 meter transceivers up to
35. Watts and normal operation and power were restored.
  Without failing.
  Ron  W4BIN - Understanding is much better than
                                    knowing how.
