OR if you can't be close to any of those you can join by audio with any standard phone. Just follow the directions below. No software needs to be loaded or installed. Anyone can join and non members are welcome. Details are here: https://www.miqrp.net/zoom Zoom ID: 811 0835 6229 The topic for Thursday, 24 April will be an OPEN FORUM. Pete WK8S Ed AB8DF Ernie N3ETE Tony W8CDC Stan WB8QJZ Casey KC9IH The bands have been crummy lately. TAXES! Pete is getting an old National five tube receiver. The weather is improving and we are all getting antsy to do some POTA. Stan is still playing with SSTV and the ISS. He had a good pass yesterday but got sidetracked with a ham radio zoom meeting. Another satellite starts in a couple of days so he may try it. He is also working on the DMR Net Michigan One Net https://www.michiganonedmr.net. This sounds very interesting and several of us will be checking it out. Tony is still trying to fix his TenTec. Ed got some color burst crystals to bring to Hamvention and the Michigan Mighty Mite Revival at club night. He also got some non inductive 250 watt resistors. He will build a high power dummy load with them. Pete is working with his Zbitx https://www.hfsignals.com/index.php/zbitx/. The recent firmware updates have improved the rigs performance. Need to look at 40 meters for the CW practice sessions and maybe even for the clubs net. We talked about the FCC issuing callsigns to stations and the ability to get a call sign outside of the station's area. Like a Michigan station being able to get a AB6XX callsign. We talked about tariffs and what they may mean for us QRPers. We are all in a wait and see mode on the tariffs. Pete is trying multiple elevated radials with POTA verticals. He is also looking at towers including a ALM-31 - US Tower. The agenda for the 24 April QRP Chat: Ernie to do a short introduction and acknowledge any new folks to the Zoom chat. The topic for next week will be an open forum. During the open forum anyone can take the floor. We will go one by one until all have had a chance to have the floor. Files, pictures and presentations can be shared if you have any. Please try to stay muted when someone has the floor. Thanks Ed AB8DF
