The April 2025 issue of the QRP Quarterly was mailed out on April 14th, 2025. We send them out first class mail to the US and use a 3rd party mailing company for the DX issues. The US Postal system is responsible for delivery. 18 days to deliver first class mail seems to be more commonplace than ever. I don't know why. If your copy has not arrived by May 14th, let us know and we will see what we can do on the shipping end. 73 de KB9BVN Membership Manager -- 72 de KB9BVN

Have others received their April QRP Quarterly yet? Before I blame the post office for loosing it, I wanted to see if others had received theirs yet. Thanks, Matthew NE3U

Hi all. With the most recent issue of QRP Quarterly landing in mailboxes I want to draw your attention to “QRP-ARCI News” starting on page 4. This month is the Board of Directors elections for QRP-ARCI and with Dick G0BPS and Ed W1RFI both deciding to retire after years of service, we know we will have 2 new members join the board after the election. Candidate summaries and voting information is in the article. As outlined it the club bylaws, only paid subscribing members of QRP-ARCI receive a vote - so please do not publicize how to vote in this public forum. New Board of Directors members will be announced at the banquet at FDIM. Thanks 73/73 Jeff Hetherington VE3CW / VA3JFF

The sooner you send it in the better. if you need some extra time, send email to editor@... and work it out. Articles can be in .DOC, .DOCX, .PDF QRPARCI membership is forever, if you are an active member that means you subscribe to the QQ. If you do not subscribe but you have an ARCI number you are considered an inactive member, which means you don't subscribe to the QQ.

Instead of the back issues, you could buy a QQ DVD with ALL the issues since time began, or with the last 20 years only. The DVD is updated with every single issue. So if you missed the last issue, buy the DVD and it'll be on there. QRP-ARCI does not sell or rent our membership email list.

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.
