printed circuit board

New printed circuit board effort to create ARES project for Arduino-based SWR meter & antenna analyzer 

Based on some qst and other articles that showed just how easy this is with the new Si5351 chip that can make ANY frequency up to 160 MHz -- feed into swr bridge & measure antenna SWR at any desired frequency

WILDFIRE FULL SCALE EXERCISE PLANNING GROWS

Vann Chesney & John Truope met with Mike Sherrill of Forestry and gained new grasp of ways to improve their Exercise.   Generated a written synopsis!   Related:  Jeff Capehart is working to fold in the MARC group into our Feb 24th Symposium Mini Full Scale Exercise.  THANKS GUYS!!!!


Georgia ARES training was excellently done!   > 200 participants in Forsyth, GA -- including Rosemary and Gordon!


EMERGENCY SYMPOSIUM GOES PAST 30 PARTICIPANTS FROM TWO STATES

CHIEFLAND REPEATER IS NOW READY FOR INSTALLATION

Prototype EMP Raduino Protection Circuit Constructed for EOC Vacuum Tube Rig

TESTED -- Good VFO Signal!

Shands Repeater
Shands repeater is ready for installation.  
Since the photo: top screwed down, handles added, dielectric grease on important connections.  Installation expected mid January.

SB-100 EMP PROOF RIG SPECIFICATION

TWO REPEATERS NEARING COMPLETION
finishing repeater
Gene Culbreath, Vann Chesney and Rosemary worked tirelessly on Wednesday -- and we have two digital repeaters nearing completion.   Rosemary soldered power harnesses, Gene helped everyone and also prepped harnesses; Vann worked steadfastly at soldering together another $25TNC; I built another micro SD chip.   Main holdup was I couldn't find any 8-pin mic connectors to build the final audio connectors.   Using a Baofeng, however, we tested NF4RC-9 --- WORKS!!!!!   That will go to SHANDS & hopefully with a MICROWAVE link attached.   GREAT WORK, GANG!!!!

TUESDAY ENORMOUS PROGRESS

1.  Rosemary and I built FOUR wood go-box shells.

bOXES

2.  Rosemary, I and Vann sawed, cut / cracked and separated TWELVE small mic preamp boards/receiver turnoffs, from larger circuit boards (my own design) for others to use.  

Cutting boards

mic preamps

3.  We put 4 Raspberries together (in the plastic case with heatsinks):

Assembling Raspberries

4.  And TESTED four rigs, finding two good ones

5.  And then MOUNTED all that stuff so far:

Half Finished Repeaters

6.  Then we CALIBRATED Two Raduinos

7.  Then we PROVED that a Raduino can  fully Drive an EMP Proof SB-100 Heahtkit 100-watt HF rig -- giving it full digital frequency accuracy -- and we measured several cyrstal frequencies of the EOC Heathkit.  

And then we quit for the day!!!  Start up again tomorrow at 9 AM. 


MultiBand Bitx's in testing

Rows and rows of push-pull output, multi-band bitx-type SSB transceivers moving into calibration and testing in India.   Size of the main board if 6" x 5.5".   There is a digital Raduino which produces most of the VFO and other required frequencies.   Appears to run on at least 4 bands, likely with double the power of existing bitx40's.   Intermediate frequency is in the 40 MHz range --- so far easier image rejection.   With controllable BFO (Raduino-developed) much easier to switch upper/lower sideband.   All those crystals you see --- are the IF filter.   Price is not yet determined and not yet available but this could be a GREAT starter rig for hams or EMCOMM.


EOC EMP-IMPERVIOUS RADIO

POWER CABLE & MIC FINISHED

Working radio with mic & cable

SB-100 now has power supply & cable finished, mic connector changed to standard CB 4-pin; works with standard powered CB mic.   A working rig ready for DIGITAL!  and like a try at using a Digital DDS Raduino VFO.

EOC ANTENNA PROJECT

Antenna meeting went well and now Moorhouse is wanting DEADLINES for antenna project goals.....good sign.


Technician Student Antennas

Five student-built antennas with Cindy & Art teaching soldering techniques --- best Technician Course I think we've ever run.    Santa Fe College fantastic room with antenna in trees behind building... we filled their heads with RADIO KNOWLEDGE!!

Draft North Florida Hospital Proposal

They got it and they thought it was less expensive than expected....


BITx40 SUCCESS!!

Just keep rolling on!!!  Now have the little transceiver prelim. working on 80 Meters as well as 40!   Upper & Lower Sideband, voice, digital (CW easy).

UNRESOLVED ISSUES IDENTIFIED IN MAY 2017 HURRICANE FULL SCALE EXERCISE

#6 EOC inadequate antennas, both HF and VHF -- and UHF also!!
#7 Simplex repeater needs more sensitive receiver
#9New transceivers for EOC to allow more frequencies to be monitored -- not installed, no extra antennas available
#11No satisfactory HF amateur or SHARES antennas at EOC -- ARES practiced slingshot temporary antennas in trees south of the building as replacement
#12Partial:  unclear if the ARES member has better HF antenna tuning assets/capabilities at this point.
#15Easton Newberry antennas not installed; worse, there is no transmission cable passthrough out of building.   There are no antennas at the Senior Center.  
#26Winlink Peer to Peer Training -- not yet accomplished!

Note that hard work has actually RESOLVED 23 issues!!!  The ones in the table above are the identified issues from May 2017 that remain.   #11 was documented in July of 2016.   

Building Waterproof Shelter Go-Box VHF Radios

How-To & News Article about Alachua GOBOX Construction

(Three go-boxes put together RAPIDLY by ARES Volunteers)  


SHANDS HOSPITAL DIGITAL STATION PLANNING

Scott Coker, a local ham and part of the ShandsCair flight team, gave me a tour of where we may be able to emplace a digital station to assist Shands in emergency comms.....but let me say that they already have an IMPRESSIVE amount of 800-MHz, etc comms all over the state -- our value-added is modest but longer-range.   Our ability to both control & communicate with our systems DIGITALLY (exactly as he does) is key to this endeavor.  

Shands VHF amageur antennas

One of TWO vhf ham antennas is encircled.   They aren't high, but I did successfully connect to Ocala KG4NXO-10 and NEWB with near full scale or better.  TOWER WORK is planned -- and I discussed putting in a microwave system for us (of course!!) 

Shands Radio Access

An incredible amoutn of digitally controlled repeater systems and 800-MHz etc access systems.   The shelf where we can start is encircled --- but a new rack may be next for us.   


PRE HURRICANE LEARNING OPPORTUNITY!

AR 20meter End fed antenna -- now manufactured & sold by LNRPresicion.  

SATURDAY 8/19:   Jay Garlitz, Susan Halbert, Ed Gray and Gordon Gibby met at the Dental Tower and soon Jay has us ON THE ROOF again examining where we can put microwave and vhf antennas to turn W4DFU into a powerhouse Emergency Comms resource for the University & County.

DentalSouthTowerHF

South tower on Dental roof, HF beam.  Possible site for 24dBi parabolic aiming atTom's Antenna/ St.Francis/ Clay Electric

Spare Brackets South Tower

Spare brackets (on white blocks) could take a metal pole mast & hold parabolic.  

Dental North Tower

VHF tower at the North end of the Dental building -- possible site for  MESH onidirectional antenna to serve the University and beyond.  

From the roof, you can easily see direct line of sight to the Seagle Building South Windows.....and I have a colleague who lives on the next to highest floor.....

inexpensively from a commerciallly available product -- cut off their connector and you find a RED (+) and BLACK(-) wire -- Put 20-24 vdc on these wires and the big black female connector has POE!  Allows you to build a Microwave Go-Box that can run from 12V (battery or vehicle) and still power NanoStation or Bullet.

$7 POE Injector (you actually get TWO)
