Hello to all, well another POLLEN and RAIN rich month has passed and another one is still ahead of us, along with our number two enemy down here in the south....LUV BUGS..... YES... they are back! I have only seen a few, but mark my works, these paint and wax destroyers are SOON TO BE COMING... to a yard, highway and winshield near you!!!
Don't forget.....SPECIAL OLYMPICS is later this month, so be sure to get in touch with Bob - WB5FBS and get signed up for your favorite event early and check those HT batteries, they are only good for a few years or even less, if left unattended. most require complete discharge once in a while.
While it may be convenient to leave them on charge all the time, remember, most of the chargers today, may have fancy circuits and stuff, but are still susceptable to power line surges and spikes, so check them regularly, remove them from the charger and let the radio operate for a full discharge and pay attention to how long it lasted on Rx only mode. Also...use a Sharpie or other method on a piece of tape placed on the battery when you replace them with new, so you will have a reference of how many years of service they give.
It is also time to start checking your go kits/bags/boxes and make sure you have fresh water, food supply, non-rechargeable and rechargeable batteries on hand for all your battery powered accessories that are part of your kit.
Hope to CU at the meeting at Options on the 14th. it sould be an informative one!!

ARES Report (Pat KE5KMM, EC): Sunday Night, a standby net was run and some hams checked in - due to front, wind, and a tornado warning, and there was no report of local damage.
(Ed KE5GMN, DEC): GOHSEP did a radio test the previous week with a pass on FM nets & Winlink. They found their propagation issues to address, and this was their first successful ham test.
Memorial Book Donations: The club has a backlog of memorial book donations. A list from Bob WB5FBS was passed around showing a list of passed club members and family members since the last time the club had made donations, since the program had expanded in scope to include family members.

==> Faster, More Contest-Friendly FT4 Digital Protocol Beta Version to Debut on April 29
A new, speedier, more contest-friendly digital mode is just days away, initially in beta form. WSJT-X developers say serious work on the new FT4 protocol began shortly after the FT8 Roundup held last December 1 - 2. The goal was a mode that could compete with RTTY contesting in terms of contact rates, while preserving many of the benefits of FT8. ...
==> Science and Technology: An Ultra-Small Transmitter for VLF?
A study, "A high Q piezoelectric resonator as a portable VLF transmitter," by Stanford University SLAC National Accelerator Laboratory researcher Mark A. Kemp et al., in the April 12, 2019, edition of Nature Communications describes using a small rod of lithium niobate and taking advantage of the material's piezoelectric properties to convert an imposed voltage to a mechanical effect, which in turn radiates an electromagnetic current.
The National Accelerator Lab describes the research in an article, "SLAC develops novel compact antenna for communicating where radios fail," which said a new type of pocket-sized devices "could be used in portable transmitters for rescue missions and other challenging applications demanding high mobility" where conventional radios don't work, such as under water, through the ground, and over very long distances through air. "The device emits VLF radiation with wavelengths of tens to hundreds of miles. These waves travel long distances beyond the horizon and can penetrate environments that would block radio waves with shorter wavelengths." ...
==> IARU Argues for Protection from Wireless Power Transfer Spurious Emissions
The International Amateur Radio Union (IARU) was represented April 8 - 10, when CEPT Committee SE24 - Short Range Devices met in Ankara, Turkey, to undertake further work concerning wireless power transfer/transmission (WPT). SE24 is considering WPT for electric vehicles (WPT-EV) and also for generic applications.
IARU already provided extensive input on the potential impact on radio communications resulting from spurious emissions from WPT devices, as detailed in CEPT ECC Report 289, published in January. ...
==> Astronaut and Pioneer for Amateur Radio in Space Owen Garriott, W5LFL, SK
Owen K. Garriott, W5LFL, the US astronaut who pioneered the use of Amateur Radio to make contacts from space, died April 15 at his home in Huntsville, Alabama. He was 88. Garriott's ham radio activity ushered in the formal establishment of Amateur Radio in space, first as SAREX (the Shuttle Amateur Radio Experiment), and later as ARISS (Amateur Radio on the International Space Station). ...
==> ARRL and FCC Sign Memorandum to Implement New Volunteer Monitor Program
ARRL and the FCC have signed a Memorandum of Understanding (MOU) that paves the way to implement the new and enhanced Volunteer Monitor program. The memorandum establishes the Volunteer Monitors as a replacement for the Official Observers (OO) program. Current OOs have been encouraged to participate in the new program. ...
==> Department of Defense to Transmit Interoperability Exercise Info via WWV/WWVH
The US Department of Defense (DOD) plans to start making use of a provisional time slot on WWV and WWVH to announce upcoming HF military communication exercises and how the Amateur Radio community can become involved in them. The announcements will occur at 10 minutes past on WWV and at 50 minutes past on WWVH. WWV and WWVH transmit on 2.5, 5, 10, 15, and 20 MHz. ...
==> Petition for Rule Making Calls for "Amateur Digital Mode Transparency"
The FCC is accepting comments on a Petition for Rule Making (RM-11831) seeking to amend FCC Part 97 rules that require all ham radio digital transmissions to use techniques "whose technical characteristics have been documented publicly." The Petition, filed by Ron Kolarik, K0IDT, of Lincoln, Nebraska, expresses concerns that some currently used digital modes are not readily and freely able to be decoded, and it asks the FCC to require all digital codes to use protocols that "can be monitored in [their] entirety by third parties with freely available, open-source software," per Â§97.113(a)(4). ...
==> MIT Requests FCC Rules Waiver for Medical Monitoring Device
The Massachusetts Institute of Technology (MIT) is seeking a waiver of some Part 15 rules in order to obtain FCC certification of its WiTrack System, a swept-frequency ultra-wide band (UWB) indoor medical monitoring device. According to MIT, the WiTrack System uses an indoor swept signal of up to 2.5 GHz in the 6 - 8.5 GHz band to passively monitor mobility, breathing, and other physiological signals in patients and senior adults...
==> AMSAT, ARRL Comment in FCC Orbital Debris Mitigation Proceeding
AMSAT has told the FCC that several proposed rule changes related to the mitigation of orbital debris would have an extremely detrimental effect on both the Amateur Satellite Service and AMSAT's ability to launch and operate new satellites, including AMSAT's upcoming GOLF satellites. AMSAT filed comments on April 5 on an FCC Notice of Proposed Rule Making in IB Docket 18-313. AMSAT argues that amateur satellites often have longer mission lifespans than other small satellites and that the FCC should take a mission duration of 5 to 10 years into account when determining whether or not an amateur satellite will meet the orbital debris regulations, either by transferring to a parking orbit or re-entering the atmosphere within 25 years of mission completion. Current practice is to assume a "zero-year" mission and to require that amateur satellites meet the debris regulations. ...
