WDCX John Dade has asked a question I had not thought of, and I do not know the answer.
When I last tuned-up I have not gone back to re-check the tuning for weeks or months. I can’t even remember what the weather was at the time I tuned, although my documents might have at least that much information, since I kept a record at that time which I should look up.
I can tell you this… the area coverage of the signal scares me a little because it goes so many blocks in some directions.
A strange thing is that some days the signal goes a lot farther than other days, and it doesn’t seem to be weather related, as sometimes this happens when it’s dry or wet or warm or cold.
Here’s an interesting thing that’s happening right now.
A giant 100-foot-plus tree as big around as Chris Christie is being taken down RIGHT NOW! The tree has stood about 12-feet from the Wintenna where my AMT5000 radiates. Will the tree removal affect tuning?
I still have a few Edit Minutes, so I’ve grabbed my RF JOURNAL, in which I document technical experience with all my transmitters.
I see that on June 5, 2013 I played with power settings on the AMT5000. I ran for a while at minimum power, which is 12.8mW, then ramped up to maximum power, which is 319.3045mW. On my spectrum analyzer this ranged from 27dBm to 45dBm. No other observations were made at that time. Following the experimentation the power was set for 100mW to the final.
The most recent tuning of the AMT5000 took place on September 6, 2013, 7:50 PM and the conditions “Dark Dry.”
