If you're coming to this page because we just had a QSO, this is probably where I was operating from. This is my "shack" and my home office.
I was probably opearting my Yaesu FT-840, which is constantly undergoing upgrades and mods to correct design flaws from the factory that cause the PLL to unlock and to add more features that should have been included from the factory. So for, I have add or corrected the following:
- I have relocated the R2213 3W resistor to the rear of the chassis and replaced with a 30W power resistor and added a much needed heat sink. The resistor, as originally designed, always fails, and literally toasts the board as well.
- I have replaced all of the electrolytic caps on the local unit, and a lot of them on the main unit as well.
- I have added an internal Arduino based K3NG keyer with a paddle jack and command button on the rear of the chassis.
- I have added a G4HUP high-impedence buffer and pre-amp board to tap the IF, giving me the ability to use an RTL-SDR dongle and HDSDR as panadapter, complete with "click-to-tune" to tune to signals on the waterfall just by clicking on them.
- I have built a USB-to-Serial adapter that also monitors the CAT commands and illuminates a super bright green LED when receiving, and a super bright red LED during digital mode TX to make it easier to see whats going on with the rig while operating modes like JT65. It also has a flashing green LED on the front to show when CAT commands are flowing.
- I have built a KF5INZ "EZ-DIGI" soundcard isolation interface with PTT (not currently using the PTT since building the CAT interface).
Upcoming projects for the FT-840 are:
- Route some lines from the mic connector to the rear of the case to allow for digital mode AF-in while the mic is still connected.
- Make the current USB-to-Serial adapter an internal component with a USB connecton on the rear of the chassis for rig control.
- Add multi-color LEDs to the front panel and S-meter. Considering making the panel or meter backlight shift from green to red depending on the RSSI.
- Considering adding some LEDs to make the buttons readable in a low light setting since they are not currently backlit.
Here are a few pictures of the FT-840:
My other interests are cycling and kayaking.
I also enjoy spending time with my family when they feel like spending time with me (those of you that have teenagers will understand...).
I also occasionally dabble (poorly) in woodworking, mainly to make things for the kids, like this planform replica of one of the guns used in the Halo video game.
Thanks for stopping by!
