Dear Mr. Anderson:
The Federal Communications Commission has previously notified you by letter on September 3, 
2015, that it has received complaints of harmful radio interference possibly caused by equipment 
operated by your company.  This interference has been reported by an operator in the Amateur 
Radio Service.  The complainant is:
(Name withheld)
(Address withheld)
Clinton Township, MI 48038
Tel: (number withheld)
In this letter, you were advised that this problem, if unresolved, could be a violation of 
Commission rules and could result in a monetary forfeiture. For this reason, we encouraged the 
parties involved to voluntarily resolve this matter without Commission intervention.  If however 
it became necessary to facilitate a resolution, the Commission might investigate possible rules 
violations and address appropriate remedies, including monetary forfeiture.
You were further advised to inform the complainant of what steps would be taken to 
correct this reported interference problem.  In addition, if unable to resolve this matter by October 
9, 2015, you were advised to inform this office about the nature of the problem, the steps being 
taken to resolve it and the estimated time in which those steps can be accomplished.  Although 
you have responded to (name withheld) within the specified time period, and corrected some of 
the issues, the harmful interference he reported to this office still remains unresolved after a year 
and a half.
In order to avoid possible enforcement action, please advise this office by April 21, 
2017, of what action(s) you have made, or intend to make, in order to identify and correct 
the source of these radio emissions if they are being caused by your equipment.
If you have any questions about this matter, please contact me in writing at 1270 Fairfield 
Road, Gettysburg, Pennsylvania 17325 or via telephone at 717-338-2577.
Sincerely,
Laura L. Smith, Esq.
