| Field Day Battery Operation | W1ECH | 1 day, 5 hours ago |
| 6.9. Batteries may be charged while in use. Except for Class D stations, the batteries must be charged from a power source other than commercial power mains. To claim the power multiplier of five, the batteries must be charged from something other than a motor driven generator or commercial mains. |

| Virtual Meetings | NO4T | 4 days, 2 hours ago |
| Zoom has been suggested but they have issues with the sudden influx of users and hacking. https://www.washingtonpost.com/news/powerpost/paloma/the-technology-202/2020/04/03/the-technology-202-zoom-chief-eric-yuan-was-not-prepared-for-flood-of-security-and-privacy-complaints/5e860e3a602ff10d49adb7c8/ It may be a good idea to do some testing beforehand to make sure everyone has the hardware they need and that it is installed properly. Not everyone uses a computer with a headset and web cam. |

| Kenwood tw-4000A where to begin | KN6CWJ | 4 days, 7 hours ago |
| That radio draws 6 or 7 amps on transmit so you may be over loading that power adapter. You will need a heftier power supply that can supply the full transmit draw for testing. I'd suggest at least 7 amps. Zak W1VT ARRL Senior Lab Engineer |

| Suggestion 80 Meter Antenna | N8KDC | 1 week, 1 day ago |
| I'd suggest a half wave dipole supported at the center by the tower. It can be bent into an inverted Vee to use available supports. Feed it with coax to an antenna switch. A choke balun would be useful for getting rid of common mode noise. I'd use 17 turns of RG-400 Teflon coax on an FT-240-43 core. http://www.karinya.net/g3txq/chokes/ You may be able to add wires for 40M with minimal interaction if they are offset by 15 degrees or more.
