It took a lot of getting used to (it had a very steep learning curve) but I became quite good at using Eagle. I came to really enjoy the EDA software and would use it to design all kinds - [SG-230 Smartuner (Antenna coupler) investigation](https://ve3bux.com/2020/03/sg-230-smartuner-antenna-coupler-investigation/) - I am fortunate that I have in my possession an SG-230 Smartuner remote automatic antenna coupler. This unit is capable of "tuning" a wide variety of antenna configurations from 1.6 to 30 MHz at power levels between 3 to 200W (PEP) and 80W (Continuous). Contrary to my usual method of operating, I took a moment - [Characterizing a Bencher YA-1 low-pass (TVI) filter](https://ve3bux.com/2013/09/characterizing-a-low-pass-tvi-filter/) - Some time ago I bought a couple of low-pass / TVI filters from a ham-fest. It is mandatory to ensure that you are not producing out-of-band or otherwise harmful interference and so having such a filter assists in ensuring that you are in compliance with the regulations. I picked up a Bencher YA-1 52Ω 1.8-30MHz - [CHU & WWV vs Rigol DSA815-TG](https://ve3bux.com/2013/10/chu-wwv-vs-rigol-dsa815-tg/) - The other night I had a conversation with Ernie (VE3EJJ) about spectrum analyzers, etc. and he asked if I had tried tuning in CHU or WWV on the spec. an. yet. Sheepishly I said "no," having never thought to undertake such an endeavour. If the acronyms CHU and WWV are unfamiliar, they are frequency and - [FM Transmitter analysis](https://ve3bux.com/2014/03/fm-transmitter-analysis/) - It has been far too long since my last update and so I decided to do a cursory analysis of an FM radio transmitter (the kind you would use to listen to your MP3 player in a vehicle which lacks an input port). The transmitter under test is one which I purchased many years ago - [MFJ-4117 Bias Tee - 0.06dB loss](https://ve3bux.com/2020/04/mfj-4117-bias-tee-0-06db-loss/) - In order to remotely power my SG-230 Smartuner which will (temporarily) live in my attic to "tune" a large vertical loop antenna, I opted to use a bias-T to inject DC power onto the coax. Bias tees are passive components (subject to losses) which allow coupling and de-coupling of DC on an RF transmission line. - [(32-bit) Time is running out !](https://ve3bux.com/2020/05/32-bit-time-is-running-out/) - When I was compiling a new version of the ntpsec package that I use for my Stratum-2 NTP server, I noticed an interesting warning that is well known but I had never paid attention to: WARNING: This system has a 32-bit time_t.WARNING: Your ntpd will fail on 2038-01-19T03:14:07Z. This is fairly easy to explain and - [CAT control via microprocessor](https://ve3bux.com/2012/06/cat-control-via-microprocessor/) - So I have a bit of a new mini-project: I have decided to turn my attention to adding (limited) μ-(microprocessor)-control of my radio to the list of things I am working on. This whole idea stemmed from my desire to make a one-off microprocessor all-in-one satellite tracking and Doppler tuning apparatus. Essentially, a dedicated microprocessor would track - [Digital modes & the importance of synchronization](https://ve3bux.com/2020/03/digital-modes-the-importance-of-synchronization/) - When using the newest digital modes (such as JT65, FT8, FT4, etc...) to decode signals well into the noise floor, it is imperative to have accurate time. More accurately, it is important to have good synchronization. Many modern protocols used today rely on consistent start/stop times to establish decoding windows. Being ±1s becomes important! I - [Testing and improving station frequency accuracy & precision](https://ve3bux.com/2020/04/testing-and-improving-ft8-frequency-accuracy-precision/) - So your digital mode software is configured to control your transceiver via CAT control (excellent!). The software indicates that you are currently on the 20m band in FT8 mode, so your radio has been tuned to 14.074MHz USB (or digital mode, which is in-turn configured for upper-sideband). Good! Everything is coming together. You have good - [Electronics as a hobby ..](https://ve3bux.com/2020/01/electronics-as-a-hobby/) - For many years now, I have enjoyed electronics as a hobby; something to keep my grey matter engaged and a creative outlet to solve real-world challenges. I view every "problem" which I encounter to be an opportunity to devise an overly: designed, engineered, built, complicated ... (pick one) solution. Were I a real bona fide - [2 Year update](https://ve3bux.com/2019/01/2-year-update/) - Well, Perhaps it is time to pull the plug on this blog? I haven't updated in two years mostly because (unfortunately) this place has taken a back-seat to the daily grind. With two young children, there is not much time to spare (at the moment) so I find it difficult to put time into some - [Yaesu FT-8900R Repair - Part 01](https://ve3bux.com/2017/01/yaesu-ft-8900r-repair-part-01/) - While visiting family in Espanola, the three of us (Julie, Felix and I) stayed with one of Julie's cousins (Denis), who as it happens is a fellow ham (VE3OOZ). Back in May, Denis showed me some of his radio gear and lamented that he had a nice quad-band radio which had the magic smoke escape. - [Hidden attic dipole antenna installation](https://ve3bux.com/2015/12/hidden-attic-dipole-antenna-installation/) - So it has been forever since I've posted anything, let alone made any serious attempts at "playing radio" so I figured that I should change that! I've had too many excuses not to get this project done; time to make good on a promise to myself. A project which I've been meaning to complete for - [DSP232+ and the RTS / CTS fix](https://ve3bux.com/2016/03/dsp232-and-the-rts-cts-fix/) - If you own a Timewave DSP-232+ TNC and are trying to connect to it using a USB to serial adapter, then you have likely come across issues when trying to operate in KISS mode. No matter what the settings, it appears that the DSP-232+ requires hardware flow control using the RTS (ready to send) and - [On the topic of USB-to-serial adapters](https://ve3bux.com/2012/03/on-the-topic-of-usb-to-serial-adapters/) - Awhile back I saw some USB-to-serial adapters which were extremely slick. Imagine the whole package in the same form-factor as the DB-9 (serial) pin header. That's right! The whole adapter fits in the same footprint as the serial port connector which your device uses. Now instead of a USB-to-serial cable connected to your device, you - [DSP-232+ and KISS operation](https://ve3bux.com/2016/02/dsp-232-and-kiss-operation/) - While I wait for my DS1243Y-120+ samples to arrive, I thought I would spend a bit of time working with my DSP-232+ and a Raspberry Pi. Although the DSP-232+ is capable of acting as a standalone system, I would like to press it into service as a simple TNC for VHF packet and APRS use. - [Modifying a Timewave DSP-232+](https://ve3bux.com/2016/01/modifying-a-timewave-dsp-232/) - Now that I have a feedline to the attic, I can really start to make use of my radio and its accessories. Some time ago I picked up a Timewave DSP-232+ TNC / full featured radio modem. I thought it might be fun to hook up the TNC and set up a packet / APRS - [Raspberry Pi & Soundmodem - It works!!](https://ve3bux.com/2013/10/raspberry-pi-soundmodem/) - It is a bout time for an update on my Raspberry Pi APRS project. (Part 01) Many months ago I was working on getting a Raspberry Pi working for APRS work.

It was quite a unique experience as we had not planned on delivering at home, however, Felix's arrival was uncomplicated and very welcome. Everyone is healthy and I look forward to sharing the magic of radio with the little guy. - [Heliax Cable](https://ve3bux.com/2015/02/heliax-cable/) - Back in October, I acquired 250 feet (~75m) of LDF2-50 (3/8") Heliax cable for approximately $150. The cable also came with 9 x 41PW connectors which sadly are of no use to me presently as they are for the more common 1/4" Heliax. The price of the 41PW connectors alone is higher than what I - [APRS / packet radio / TNC fun](https://ve3bux.com/2014/07/aprs-packet-radio-tnc-fun/) - Hi all, I've had a crazy summer so far, and as a result I've had little time for tinkering and ham radio. Despite this fact, I've managed to acquire a new (to me) piece of kit: a Timewave DSP-232+ DSP radio modem. I purchased this unit from Rob (VE3???) for a decent price - a - [Changes ...](https://ve3bux.com/2014/01/changes/) - Well, the end of an era has come. I just cancelled my 15+ year colocation contract in favour of hosting my domains in a more budget friendly sense. In a way, I regret cancelling the colocated server service as it has afforded me great autonomy with my hosting, etc. though I have failed to fully - [APRS & Soundmodem](https://ve3bux.com/2013/12/aprs-soundmodem/) - I was not satisfied with my prior results with the APRS testing, so I setup soundmodem in an Ubuntu environment on my trusty netbook and set-off to decode packets. As expected, everything went well - soundmodem was decoding local packets with little trouble. To be sure that the sound card itself was not at fault, - [AFSK packet investigation](https://ve3bux.com/2013/11/afsk-packet-investigation/) - To further my investigation as to why the soundmodem TNC appears to be flaky, I decided to scope the output of some local APRS transmissions. After setting the squelch to the point where no background noise was seen / heard, I set my DS2202 oscilloscope to single-shot trigger the AFSK data. To see the audio - [Soundmodem update](https://ve3bux.com/2013/11/soundmodem-update/) - So I had some initial success with the Raspberry Pi and using soundmodem as a software TNC for APRS packet radio. The success seems to have been short-lived. I am able to decode packets from test wave files that I've been using, but the APRS over the air does not appear to be working! For - [Interface v0.20 laid-out](https://ve3bux.com/2013/10/interface-v0-20-laid-out/) - Having recently explored the signal integrity issues in the Interface v0.11, I've re-tooled the board to use the TY-311P transformers in v0.1 which meant a total redesign of the layout. In the most recent version, I've grouped the components in functional blocks which in principle should reduce any digital noise in the analog side of - [More testing ...](https://ve3bux.com/2013/10/more-testing/) - I thought that I would do a little more side-by-side comparison between the transformer and the capacitor methods of signal isolation. My test bench consisted of: DG1022 function generator DS2202 oscilloscope Sound Card Interface v0.11 As I found that there was a direct voltage saturation type effect of the DA102MC transformer in previous testing, I - [Sound Card Interface v0.11 - initial testing](https://ve3bux.com/2013/10/sound-card-interface-v0-11-initial-testing/) - So I received my v0.11 boards back from the fab house and soldered one up last night to begin testing. I managed to squash a few bugs in the initial design, as well as identify a couple of new ones (which were relatively easy to bodge for now). Luckily the only minor issues I found - [Sound Card project delayed ..](https://ve3bux.com/2013/10/sound-card-project-delayed/) - The boards never made it from the fab house - I've got another batch which should enter the production stage soon.

I do my very best to help my fellow radio hobbyists within the scope of my abilities, which in most cases means - [Radio-Computer Interface](https://ve3bux.com/2013/06/radio-computer-interface/) - So I'm back on the topic of interfacing a radio to your computer - this time with a bit of a twist. In the past, I've discussed methods by which you could decouple your radio from your computer (and the importance of this) and I've even gone as far as to design a couple of - [New test gear & and update](https://ve3bux.com/2013/06/new-test-gear-and-update/) - So I've been very bad at updating lately but to be honest, there hasn't been a whole lot to say! Back in April, I placed an order for some test equipment which I've been drooling over for a few years. It took a year's worth of working extra shifts, saving birthday and Christmas money, etc - [Moved in - lots of work still](https://ve3bux.com/2013/05/moved-in-lots-of-work-still/) - So its been a month since my last update here and I figured this is long over-due. We've moved into the new house and have started tackling some of the myriad projects we bought with the house. I started by installing the house's first sump pump since it was built - it was long over - [Update: Nine days and counting (down)](https://ve3bux.com/2013/04/update-nine-days-and-counting-down/) - Well, only nine days until we take possession of our new house and I couldn't be more excited!

I really am a geek. There was no OVMRC radio class tonight and I was a bit bummed out. This week's homework is to memorize the phonetic alphabet and to learn some of the Q-codes.

I attribute the score to the random chance that I get all of the easiest possible questions from RIC-8 (the Advanced question bank) and fumbled on what should have been simple questions.
