After 2 days and 18 hours of use the battery light was just an outline. It has not started blinking yet. So Samsung 30q 3000mAh 18650 last 18 hours use with 3 nets per day. I have some Sanyo 3450mAh coming since imb was out of the Samsungs. Great upgrade for the FT-70.

Extra Class - We still have room #QST

Orion - AI6JB
 

Good Afternoon Everyone!

Are you looking to upgrade to Extra?  Our Extra License class is starting on Tuesday, February 2nd, and we still have room.  If you are interested, please email me at ai6jb@... as soon as possible.

The class will be conducted online via ZOOM on Tuesday nights from 7 - 9 PM.  The course will run 10 weeks ending on April 6th.

In addition to 10 weekly sessions, two (2) in-person labs will be held.  In the first lab, we will show you how to setup a portable HF digital station and give you hands-on time working FT8/4 or PSK31.  The second lab will be devoted to constructing antenna stubs were you learn how to attach PL259 connectors to coax and tune stubs.  If you don't know what a stub is, we'll tell you in the class.  ;-)

Cost is $40 for members and $65 for non-members.  Fee includes an ARRL Extra Class License manual and lab materials.  VE session fees are not included.

If you have any questions, please do not hesitate to ask.

Radio Direction Finding Project Contributors? #wanted

Jon - KI6RT
 

WANTED: Members interested in contributing to a RDF (Radio Direction Finding) project


PROJECT CONCEPT:
The RDF project concept builds off of a well known technique employing Doppler Shift methods. Rather than building 'yet another RDF' the concept here is to create a modular RDF system that can be used:
  1. Mobile when participating in a Fox Hunt (transmitter -- similar to geocache but better :)
  2. At home to see where signal sources are coming from -- i.e. whatever frequency your receiver is tuned to (with an appropriate antenna array)
  3. As a crowd sourced (various APRS enabled RDF units that may be mobile or stationary) triangulation service that aggregates multiple APRS RDF vectors onto a map overlay -- locate transmitters, noise sources, deployed ARES members
Project 1 would cover a common Doppler assembly that would switch the antenna (electrically simulate rotation of a mechanical antenna at ~500 RPM), recover the Doppler phase shift, generate a data packet containing the Apparent 'Angle to the transmitter' and GPS position. If 'someone' gets ambitious data packet may also include 'Magnetic Heading to the transmitter' along with source travel direction, speed, elevation, etc. 

Project 2 - 4 would be various consumers of the RDF data packet. Given the number of experienced computer, Arduino, Raspberry Pi, APRS talent there could be one of a number of implementations on how the data is rendered. 

Implied in the concept is an antenna array of 4 vertically antennas. Would probably provide a reference design for VHF (130-170 MHz) and UHF (400-500 MHz) and given the nature of Hams would probably evolve into a range of interesting objects that sit on top of cars or houses :)

WANTED:
To get this project running we need mad skills! EEs that can help with antenna designs, circuit designs, circuit layouts, etc. CS or programming gurus to get the data plotted onto a portable display or a computer screen with map integration. Web hackers that can publish a federated view of the various RDF data sources onto a club web page. Program Managers who can over see the various threads of the project and track/report on status/progress etc. Given the nature of club projects I assume there may be multiple teams working on the same task that way the first to complete or a best of the best can be evaluated by a 'selection committee' for the final system? How about a steering committee? A Congressional task force to write voluminous requirements documents that no one will read? Perhaps aesthetics oversight committee to ensure the final product passes HOA requirements? You get the idea LOL

Well if you wish to learn more ask Brian (AI6US) or Jon (KI6RT) on the W6EK repeater. If interested in attending the Zoom please email me at jon@... and I will include you in the Zoom kick-off pow-wow tentatively targeting Tuesday 2/2 @ 1900 to discuss the project and perhaps form an initial program team.

I had recently gotten a FT-70, and this caught my interest. I contacted the maker at diyham.ru. Virtpil@... incase anyone wants their email to order one. It was $40 shipped via paypal. Arrived in a week to my door. Well made and working perfectly so far. I am using Samsung 3000mAh 18650 button top batteries. I will report back with battery life in a few days.

Re: FCC Issues Advisory Ahead of Inauguration, Warning of Illegal Radio Use

Ron - KA6AUI
 

It would be nice to see rioters arrested and not try to be concerned about their means of communicating.  I can't image the FCC checking people in a crowd to see what kind of radio/phone or whatever they might have.

Oh well, a new year, new strange things happening!


Re: FCC Issues Advisory Ahead of Inauguration, Warning of Illegal Radio Use

Alan - W6WN
 

Right. Most people probably don't know the difference between Ham Radio and "PRS," and lump them all together.

Questioning the OP on the linked-to Reddit feed seemed to confirm the D.C. chatter was GMRS (and, by extension, FRS, which can monitor-only GMRS Repeater transmissions).

As an aside to this, we noticed a big uptick in chatter in Coloma right after Christmas. Turns out a bunch of new FRS radios families were getting for Christmas had come stock out of the box tuned to Ch. 22 / "Tone 1" (= 67.0 Hz PL). Transmissions up and down the river were unlocking GMRS radios in the Coloma Lotus Neighborhood Radio Watch group set up for our GMRS Channel 22 Repeater, also using 67.0 Hz on both transmit and receive.
