Tuning Frequency is Far Off

[ocona040]

Checklist:

• I updated to the latest version available
• I double-checked my hardware connections
• I checked that my MQTT broker is otherwise working

Release with the issue:
v2.2.7

Last working release (if known):

Hardware, Operating System, Python version:
Rasp Pi Zero W
AS3935

Description of problem:
Tuning lists average frequencies around 45,000 HZ, instead of 500,000. Yesterday it showed 125,000 average, but I don't believe I changed anything. No tuning cap gets it close to the ideal 500,000. Any ideas what could cause this? Here are the tuning logs:

* Please allow a long time for this function to stop. It should take a little over 3 minutes to test the 16 values

I have the same problem with the same configuration

I had a similar problem in a pi zero W, I don't think it can handle that high of a pulse freq so I changed the divider to 128 and it worked
