If you appreciate this service and wish to donate, funds received will be used to add a remote tuner to the HF horizontal loop at the local public high school station. Payments are not required to use this service, nor do they imply an added benefit such as a higher grade of service or continuation of the service. Sufficient funds have been received to repair the vhf and uhf antennas at the high school. Thank you!
