对，打广告。

绝无仅有的几乎接近白送，需要的人还会心存感激。

我没太多精力搞这些，供不应求并不愁卖。

一个真实故事：业余无线电帮助救援迷路的穿越者Editor's note: The following event took place on Sunday afternoon, December 11, 2022, and was told to ARRL News by Raul "Skip" Camejo, AC1LC, Public Information Coordinator for the ARRL New Hampshire Section.
The amateur radio repeater on the summit of Gunstock Mountain helped connect the lost hiker in a remote area of New Hampshire. The repeater is affiliated with New England Digital Emergency Communications Network, NEDECN.
A New Hampshire man and his dog went out for a day hike yesterday in the Belmont area of central New Hampshire. Things went well until his cell phone battery died. With darkness near and a prediction of snow, a leisurely day hike was quickly turning into a serious health and safety issue for the hiker.
Fortunately for him, he is also an amateur radio operator and brought along his digital mobile radio (DMR) handheld radio with him. With no cell phone capability, he made a call on the DMR New Hampshire statewide channel through the Gunstock (Mountain) DMR repeater, seeking assistance. His call was answered by Bill Barber, NE1B, who was monitoring the channel. The hiker asked Barber to call his wife, because he could not text or get "pinged" with his dead cell phone. Barber contacted the hiker's wife, and she was glad to hear that someone was in contact with him. Unfortunately, he did not know exactly where he was and believed he would have to walk through brush for an hour or more to get to a road.
His wife called the local police department, who began a search with their local fire department. Amateur radio was the only communication from about 4:30 to 6:30 PM. Barber was able to make contact with Rick Zach, K1RJZ, who lives closer to the search area, and was familiar with the area's snowmobile trails and roads. Zach coordinated communication between the responding police units and the lost radio operator on the New Hampshire Statewide talkgroup.
Police and fire units attempted to assist in the search by activating their sirens in different locations to try to obtain a location on the ham operator, but he was not able to hear them.
Another amateur radio operator, Chuck Cunningham, K1MIZ, was monitoring the events on Net Watch and noticed that the lost ham had accidentally changed channels. This information was passed along, and 2-meter DMR communication continued until the lost ham walked out to a road and was able to advise searchers of his location. The search and checkout ended successfully at 6:30 PM.
Thanks to the efforts of Bill Barber, NE1B (ARRL Life Member); Rick Zach, K1RJZ (ARRL member), and Chuck Cunningham, K1MIZ.
Barber listed some very important lessons learned from the incident:
Radio batteries last longer on DMR radios than on analog mode.
Even his wife had trouble with her cell phone coverage at home.
Monitor your local state DMR channel to help others nearby.
You may want to program 146.52 FM next to your state channel for signal strength direction finding if and when you're out of repeater range. Some hams still monitor 146.52 MHz simplex.
Stay on the primary channel until you know more hams are nearby to direction find your signal.
Hike with DMR. Network sites cover many areas of New England that do not have any cell service.
Hike with a flashlight.
And I would like to add one more item to the list. My son is one of the leaders of Pemigewasset Valley (New Hampshire) Search & Rescue Team and unfortunately responds to too many calls for lost hikers. One very important item that he stresses is that hikers file a "flight plan." Let someone who is not going on the hike know where you are going, how long you expect to be gone, and what communication equipment or capability you have with you. This also applies if you are going out hunting, fishing, or boating.

[tr]编者:
[tr]以下事件发生在2022年12月11日周日下午，由ARRL新罕布什尔州公共信息协调员Raul“Skip”came jo告诉ARRL新闻。
[tr]冈斯托克山顶上的业余无线电中继器帮助新罕布什尔州偏远地区的迷路徒步旅行者联系上了。该中继器隶属于新英格兰数字应急通信网络。
[tr]一名新罕布什尔州男子和他的狗昨天在新罕布什尔州中部的贝尔蒙特地区进行了一天的远足。一切都很顺利，直到他的手机电池没电了。随着夜幕的降临和降雪的预测，一天悠闲的徒步旅行很快变成了徒步旅行者严重的健康和安全问题。
[tr]幸运的是，他也是一名业余无线电操作员，随身带着他的数字移动无线电(DMR)手持无线电。由于没有手机功能，他通过冈斯托克(山)DMR中继器在DMR新罕布什尔州全州频道打电话寻求帮助。NE1B的比尔·巴伯接听了他的电话，他正在监听这个频道。这位徒步旅行者让巴伯给他的妻子打电话，因为他的手机没电了，不能发短信或被“pinged”。巴伯联系了徒步旅行者的妻子，她很高兴听到有人和他联系。不幸的是，他不知道自己确切的位置，他认为他必须穿过灌木丛走一个多小时才能到达一条路。
[tr]他的妻子打电话给当地警察部门，警察部门与当地消防部门一起开始寻找。从下午4:30到6:30，业余无线电是唯一的通讯方式。巴伯能够与住在搜索区域附近的里克·扎克(Rick Zach，K1RJZ)取得联系，并熟悉该区域的雪道和道路。扎克在新罕布什尔州全州通话组协调响应的警察单位和丢失的无线电操作员之间的通信。
[tr]警察和消防部队试图通过在不同地点启动警报器来协助搜索，试图获得ham操作员的位置，但他听不到他们的声音。
[tr]另一名业余无线电操作员查克·坎宁安(Chuck Cunningham，K1MIZ)正在“网络观察”上监控事件，并注意到丢失的火腿意外地换了频道。这个信息被传递下去，2米长的DMR通信继续进行，直到迷路的火腿走到一条路上，并能够告诉搜索者他的位置。下午6:30搜索和结帐成功结束。
[tr]感谢比尔·巴伯的努力，NE1B (ARRL人寿会员)；里克·扎克，K1RJZ (ARRL成员)，查克·坎宁安，K1MIZ。
[tr]巴伯列举了从这一事件中吸取的一些非常重要的教训:
[tr]DMR收音机的电池使用时间比模拟模式长。
[tr]甚至他的妻子在家里也有手机信号覆盖问题。
[tr]监控你当地的DMR频道，帮助附近的其他人。
[tr]如果你不在中继器的范围内，你可能想在你的国家频道旁边设置146.52 FM来进行信号强度测向。一些ham仍然监控146.52 MHz单工。
[tr]保持在主频道上，直到你知道附近有更多的火腿来定位你的信号。
[tr]和DMR一起徒步旅行。网络站点覆盖了新英格兰没有任何蜂窝服务的许多地区。
[tr]带着手电筒徒步旅行。
[tr=rgba(0, 199, 139, 0]我想在清单上再增加一项。
[tr=rgba(0, 199, 139, 0]我的儿子是Pemigewasset Valley(新罕布什尔州)搜救队的队长之一，不幸的是，他回应了太多寻找迷路的徒步旅行者的电话。他强调的一个非常重要的项目是徒步旅行者提交一份“飞行计划”让不打算徒步旅行的人知道你要去哪里，你预计要去多长时间，以及你有什么通讯设备或能力。这也适用于你外出打猎、钓鱼或划船。
