| New ARRL website / changes? | PE1HZG | on 1/4/22 |
| And my computer still flags the ARRL site as "Not Secure" !!! I concur that Forums really, really should be more easily accessible. | ||

| Lets reach out to older hams in Nursing Homes | N0HWJ | on 3/7/20 |
| I live in a suburb of Philadelphia, and agree that ham radio is a great hobby for seniors. Over the past few years, I've given a one-hour talk / demo about ham radio to several groups of seniors. I also contacted a local veterans home about this, as well as a huge nearby senior living facility. And I wrote a dozen or so licensed hams in assisted living facilities. I was focused on showing how people with only an easily-obtained entry level license could use very cheap equipment such as an HT to communicate with other locals via the many repeaters in my area. Although I received a lot of positive comments about this, nobody was interested enough to take the next step, much to my dismay. I remain convinced that our seniors would benefit from ham radio, and that getting them on repeaters would be a good first step. But I wish I knew how to make it happen. Be well. 73 de Allan, AB3FN |

| question about interference on 70 cm band | AB3FN | on 11/2/20 |
| Its well-known that we are secondary users of the 70 cm band, but Part 97 only refers to interference to / from other specific services, e.g. mobile service near certain cities. What about other users of this portion of the spectrum? For example, the medical procedure capsule endoscopy routinely uses frequencies around 430 MHz, albeit with power in the microwatt or milliwatt range. The likelihood of those devices creating interference to a ham is pretty small, but the likelihood of us creating interference to those devices is obviously much larger. I cannot imagine any ham knowingly interfering with any medical procedure, but do FCC regulations, whether in Part 97 or elsewhere, address this? Thanks in advance for your comments and clarification. |

| Function Generators | WA4PMA | on 7/1/20 |
| I agree with Zak that a function generator has limited use in ham radio. But if somebody wants to tinker and experiment, its nice to have a variety of signal sources available. There are several extremely cheap function generator kits that will serve the average tinkerer well. A quick on-line search finds some that are in the $10-$20 range, and as a bonus these small kits are also fun to build. | ||
