Dear Mr. Aranda:
The Federal Communications Commission has previously notified you by letter on June 
20, 2017, that it has received complaints of harmful radio interference apparently caused by 
electrical or electronic equipment operated by Aranda Tooling located at 15301 and 15391 
Springdale Street in Huntington Beach.  This interference has been reported by an operator in the 
Amateur Radio Service.  The complainant is:

(Address withheld)
Huntington Beach, CA 92647
Tel: (Number withheld)
In this letter, you were advised that this problem, if unresolved, could be a violation of 
FCC rules and could result in a monetary forfeiture. For this reason, we encouraged the parties 
involved to voluntarily resolve this matter without FCC intervention.  If however it became 
necessary to facilitate a resolution, the FCC might investigate possible rules violations and 
address appropriate remedies, including monetary forfeiture.
You were further advised to inform the complainant within 60 days of what steps would 
be taken to correct this reported interference problem.  In addition, if unable to resolve this matter 
within 60 days, 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.
In order to avoid possible enforcement action, please advise this office within 20 
days of receiving this letter of what action 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.
Sincerely,
Laura L. Smith
