| Antenna launchers | WB7AEA | on 10/9/20 |
| W1AW Station Manager, Joe Carcia, NJ1Q, uses a compressed air cannon that launches a tennis ball attached to fishing line. He always seems to get the line over the branch, or fitting he was aiming at. It seems to be the preferred method, but the sling-shot works, too. Some hams use drones for such things now. I once heard a story about a trained squirrel..... Personally, I hire a tree climber. He installed a pulley on each tree intended to be used as an antenna support. It's a permanent solution, provided each halyard (rope) is maintained. Eye hooks are used to secure each pulley. Works great and no worries during wind. |

| Desense Issue | BaoFeng2020 | on 17/7/20 |
| The de-sense effect may be happening not in your repeater, but in the handheld that you are using to test the repeater. If you are listening to the output on you handheld while you are close to your repeater, your handheld will de-sense from the transmitter of the repeater. A 25 Watt repeater that is only 600 kHz away from the frequency you're listening on can de-sense an inexpensive radio. De-sensing of inexpensive handhelds caused by stations close to the tuned frequency is quite common. Try another radio of good known quality, first. Also, if the tuning of the repeater's duplexer cavities is off just a little bit (caused by mechanical vibrations, dropping it a few inches, or by someone trying to tune it by ear), it will de-sense the receiver of the repeater. Tuning the cavities for maximum rejection should be done while viewing a spectrum analyzer. Bob Allison WB1GCM ARRL Lab Assistant Manager |
