HAs anyone been in a situation when they so a freq scan and the Sennheiser G3's show no available channels? I was doing an indoor recording in a bulding that is known for low cell service signal inside and had no free channels show up. Please advise if this is the buildings issue and if I should be using a different system. Thank you!
Sennheiser G3 Band A used in the Bay Area, California.
The scan features of wireless systems are VERY BASIC....... Sennheiser, Sony and Lectrosonics do have that facility but there is a better option and that is a scanner.
For just over a 100$ you can get a very useful tool that will show you what is happening.
Keep in mind the Sennheiser units have 20 groups of 12 preset frequencies, so which ever group is selected the scan is done only on those 12.
So to do a full scan of 'preset' frequencies in the receiver unit [select group 1 >>>scan], [then select group 2 >>>> scan],[ then select group 3 >>>scan], etc, etc. To do it all it needs to be 20 times.
To find frequencies 'manually' go to U (user) group and then select / scroll up or down to find a frequency that shows no RF on the frequency indicator.
For a one system setup its easy but when you need multiple systems you need to be aware of intermods of the RF that will cause problems.
