Recipe for a future project - This is an TDOA (Time Difference Of Arrival) antenna switcher that, when combined with a radio receiver, will tell the direction to a transmitter via LEDs. https://www.byonics.com/tdoa https://k5rwk.groups.io/g/main/message/7683 https://en.m.wikipedia.org/wiki/Transmitter_hunting http://www.146970.com/PDFs/TDOA%20Phasenpeiler.pdf

Tonight I received this email: "Welcome Chris Wite KI5JBP to The Richardson Wireless Klub!"  Turns out their next MOTA is tomorrow night, which I plan on joining K5RWK  via 147.120. http://www.k5rwk.org/home/repeater-information/ To Do List: Base Station - So Many Options To Consider! https://www.gigaparts.com/yaesu-ft-dx101d-hf-50mhz-sdr-transceiver.html https://www.gigaparts.com/yaesu-ft-dx3000d.html https://www.gigaparts.com/kenwood-ts-590sg.html https://www.gigaparts.com/icom-ic-7610-hf-50mhz-100w-transceiver.html https://shop.flexradio.com/signature-series-radios/ Power Supply https://www.dxengineering.com/parts/ysu-fp-1030a https://www.gigaparts.com/mfj-4035mv.html https://www.dxengineering.com/parts/mfj-4245mv https://www.dxengineering.com/parts/asr-rs-35m-ap Mobile https://www.hamradio.com/detail.cfm?pid=71-003327 Antennas https://www.dxengineering.com/parts/dmn-x50a https://www.dxengineering.com/parts/mfj-1838 Antenna Tuner: https://ww...

It’s Official - KI5JBP

Today I passed both the Technician and General amateur radio license exams.  No Morse code testing is done but CW is still fun and encouraged to learn.  Special thanks to the VEs at WB5QNG in Plano who were able to administer the tests remotely using Zoom+ExamTools. I have a Baofeng F8HP Mobile radio - 8 Watts, dual band both 2M and 70CM bands - VHF (136-174MHz), UHF (400-520MHz).  I’m also exploring software defined radios - there are some really good SDR dongles for monitoring local transmissions and and analyzing RF spectrum.  CubicSDR and gqrx both work well with Ubuntu. https://wb5qng.org/ https://hamstudy.org/ https://baofengtech.com/bf-f8hp https://gqrx.dk/ https://cubicsdr.com/ Check out my Amazon Kindle reading library:

Rekindling old hobbies

Posting “for a friend.” After 30 years I decided to resume my studies for the Technician Class Amateur Service operators license.  Aka “Ham” for the LIDs out there like me.  I’m also going to pass the Code Exam.  But instead of painfully memorizing tables of CW codes I’m going to try the KOCH METHOD to learn reflexively. http://www.arrl.org/ http://aa9pw.com/morsecode/ https://en.m.wikipedia.org/wiki/Morse_code#/media/File%3AInternational_Morse_Code.svg https://jgweb.us/ham/hamStudy.php https://www.gordonwestradioschool.com/main/page_home_page.html

New PC Build and Benchmarks!

A week before the Coronavirus lockdown, I replaced the old Shuttle XPC computer that I built in 2010 as my primary workstation at home.  A lot has changed since then! I decided on a stylish, full sized  HTPC case with ATX motherboard instead of the Shuttle barebones kits I've been using from Newegg since 2004. I sourced the parts thru the local Microcenter in Richardson - apparently Fry's isn't what it used to be, and I didn't want to wait on shipping.  Special thanks to  The Tech Buyer's Guru  for design inspiration and component recommendations!

IoS Support on Ubunstu Studio

Reposted from  AskUbuntu .   A lot of trouble for an easy fix.   I verified with Ubunstu Studio 19.04 with iOS 13.2.3 Ubuntu 18.04 / iOS 11.4 This version of Ubuntu has the latest libimobiledevice (at the time of release) so it supports iOS 11.4. There is a propblem with the Gnome integration, though. It shows the Documents folder (app folders). In addition to the tip below by @diego, here's a simple way to get to the pictures folder (this works if the iOS Documents show up for you but not the pictures): Open the iDevices Documents folder in Nautilus. Press CTRL + L to get the real address which will look like afc://YOURSERIAL:3/ Remove trailing colon and number and press ENTER (i.e. it should just read afc://YOURSERIAL ) You should now see your iDevices system folders, including DCIM.

Firewire is NOT dead (at least not yet)

Been a while since I posted but wanted to grab some old DV files from the Video Camera.   A lot of peple report firewire support being broken in many linux distros, but figuring out how to login to my old blog was a tad bit harder than getting ieee1394 interfaces working again on my linux system! Steps for future reference 1.  Install Ubuntu Studio . Note:  While I've been using LinuxMint for many years, I felt like a change anyway. 2. Set Up Firewire IRQ Priorities.   Confirmed changes on my system: cat /etc/default/rtirq RTIRQ_NAME_LIST="rtc firewire snd usb i8042" RTIRQ_NONE_THREADED="rtc firewire snd" 3.  Reboot - Here's output of dmesg and lspci $dmesg |grep firewire [ 1.603804] firewire_ohci 0000:04:09.0: added OHCI v1.10 device as card 0, 4 IR + 8 IT contexts, quirks 0x41 [ 2.110941] firewire_core 0000:04:09.0: created device fw0: GUID 0011066600000215, S400 [ 90.935327] firewire_core 0000:04:09.0: phy config: new root=ffc1, ga...
Linux Support for the Parallax BOE-BOT (Board of Education Robot) I'm leading a robotics class for the Boys and Girls Club of Collin County on Saturdays. Today I got my BOE-BOT working with Linux over USB! (albeit the interface is still limited to the command line). Here's how I did it: 1) Download the Basic Stamp Tools for Linux from SourceForge 2) Extract to a local directory and make/make install (w/ sudo when necessary) 3) Plug your Boe-Bot into the USB port, and use the "dmesg" command to deterime the correct port. My port was ttyUSBO: usb 2-3: FTDI USB Serial Device converter now attached to ttyUSB0 usb 2-3: New USB device found, idVendor=0403, idProduct=6001 usb 2-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-3: Product: FT232R USB UART usb 2-3: Manufacturer: FTDI usb 2-3: SerialNumber: A7005rCF 4) Create a symbolic link from your USB port to /dev/bstamp and to the Parallax Tokenizer shared library: bash...
Good-bye Samba. Hello CUPS! I've finally resolved a long standing issue printing from windows PC (xp and vista!) to the laser printer attached to my Fedora based linux workstation. So far this solution has been very reliable and doesn't required SAMBA. 1) In Fedora, Define a " Raw Print Queue " and make sure its shared (select the "Generic" drop down when you reach the "Printer model" step of the wizard, then select "Raw Print Queue") 2) In Windows XP (or Vista), "Add Printer", select "Connect to a printer on the Internet", and use the CUPS URL for the raw print queue on your Linux workstation (mine is http://192.168.0.102:631/printers/Raw) 3) Print a test page from Windows. If you have a problem make sure you have the correct Windows/XP/Vista print drivers installed, just as if the printer were connected locally.

There is no 'try.’" (Jedi Master Yoda) “Look for the sudden and significant change…” (Judy Spitz)
For the Children! 2008 Softball Champions -- Corporate Challenge - City of Richardson Continuing a fine tradition of winning for Texans Credit Union, our team won gold this year with the Division D Softball tournament . We started the tournament with Game 1 on Saturday morning at 8am and led the team to a 6-2 win. The Texans then made it through the tournament with one loss (4-14) Sunday afternoon in a double-elimination gold medal round. We played the final gold medal round with lots of passion and energy on Sunday afternoon. Coming from behind with 6-8 deficit, we gained four runs to post a 10-8 lead. However, our opponents managed to tie the game 10-10 with a minute left on the game clock. The Texans again rallied with a 1 run and held our opponents scoreless in the bottom of last inning to win the gold medal 11-10. The Richardson Corporate Challenge is an Olympic style competition involving many athletic (and non-athletic events) held in the fall of each year. This charit...
Resolving GDM issues with Fedora 9 (Sulpher) GDM is not fully supported in Fedora 9 because GDM was rewritten during the GNOME 2.21 release cycle ( ref ). gdmsetup is missing so you cannot customize your login and I had issues with user switching ( Cannot communicate with GDM (The GNOME Display Manager)). Also, GDM would not put my monitor into powersaving mode from the login screen which was a real issue. To resolve I reverted back to the fedora 8 versions of gdm and fast-user-switch applet. Note: this could be "dangerous" (ie, see below - you may be required to recreate your user account). 1) Download fc8 rpms for gdm, fast-user-switch-applet and fedorainfinity-gdm-theme (required to resolve a gdm dependecy) gdm-2.20.1-5.fc8.i386.rpm fast-user-switch-applet-2.20.0-1.fc8.i386.rpm fedorainfinity-gdm-theme-8.0.1-1.fc8.noarch.rpm 2) Remove the fc9 versions of gdm and gdm-user-switch-applet $sudo yum erase gdm 3) Install the fc8 versions: $sudo rpm...

WiFi Antenna Hacks for (Almost) Free! I "stumbled" across a couple of cool tools to improve performance of your wireless router at home. The "Ez-12" parabolic reflector took a few minutes to make and really worked great. My WiFi router is upstairs. I got a 10db signal boost and my WI-FI connection quit dropping on my laptop downstairs. Ez-12 Parabolic Reflector Template: http://www.freeantennas.com/projects/template2/index.html If you are adventurous you might also try this. I’ve got everything ready but haven’t made the commitment to cut the existing wiring on my WiFi antenna. The parabolic reflector appears to be working well enough. At any rate this one was fun to build and beats spending $50 at Best Buy.

Love of My Life - Queen/Freddy Mercury (Top 5 All Time Favorites!) Love of my life, you hurt me, You broken my heart, now you leave me. Love of my life cant you see, Bring it back bring it back, Dont take it away from me, Because you dont know what it means to me. Love of my life dont leave me, Youve stolen my love now desert me, Love of my life cant you see, Bring it back bring it back, Dont take it away from me, Because you dont know what it means to me. You will remember when this is blown over, And everythings all by the way, When I grow older, I will be there by your side, To remind how I still love you I still love you. Hurry back hurry back, Dont take it away from me, Because you dont know what it means to me.

Revisiting Hardcore Roots I've recently been listening to Bad Brain's " Banned in DC " album again. Some of their reggae tracks are really worth listening too as well. Mainstream types might enjoy watching the recently released DVD American Hardcore . The rest of you should check out Penelope Spheeris' now classic film from 1981 titled Decline of Western Civilization.
