    Several amateurs with Part 5 experimental licenses for 630-meters and 2200-meters will be transmitting Field Day greetings throughout ARRL's Field Day, June 24 and 25. These station include as of June 13 but are not limited to:

    Participant updates and operational status will be posted and updated at http://njdtechnologies.net/field-day-2017-details/

    Stations at Field Day sites are encouraged to use their HF rigs with general coverage receivers capable of the receiving below the AM broadcast band and whatever antennas they might have on site to listen for these stations and others (HF dipoles and verticals are probably best, antenna tuners in bypass). Reports are very much appreciated and can be sent to the respective station operators, but stations are also encouraged to enter reports at http://w5jgv.com/enterlogs.htm AND take advantage of potential Field Day points by sending NTS traffic to the ARRL to let them know who was heard. (10-points per message up to 100 points). The ARRL's contact information is 225 Main St., Newington, CT 06111, 860 594 0200.

    This event has been organized for the fourth consecutive year to promote awareness of the new MF and LF amateur allocations ahead of opening of the bands to hams in the US. Its an opportunity where hams and ham gear come together for a fun weekend and we hope to add yet another layer to the mix.

    73 and have a safe, happy and fun Field Day weekend!

    I have found that a simple L network made from a BCB variable cap and loopstick antenna make an effective match for open wire fed antennas to common 50Z receiver inputs. 200uH inductors from the parts collection or made from winding magnet wire on a paper towel core (only an inch worth) will also do the trick nicely.

    Those who are curious can experiment with matching circuits ahead of time by tuning in the many navigational beacons in the 200-400kc range, particularly at night.

    Here's an excellent directory:
