Your brain will tell you you can’t
But do it anyway
Your body will say quit
But keep going anyway
Others will tell you it is impossible
Prove them wrong

I grew a plant from food!
I had given up on it but the ginger I bought from Kroger has sprouted! In two places. I have no idea what comes next, how long to let it grow, or when to harvest but I grew a plant from food!

Early to rise…
I’ve become an early riser again out of necessity. I feel it but I’m loving it. Nothing compares to the calm of pre-dawn and the productivity it brings.

Such a beautiful day to be a programmer?
So you want to be a programmer? Be prepared to watch the perfect spring time weather pass you by as you pound on the keys of your keyboard and day dream of working on your yard and your house.

The devil is in the details
I use a paper planner to keep me productive. I know..tech dude says what.
Today my todo list says “Reset PW”
Someone needs to be a little more specific.

The stress addict’s prayer
Give us this day our daily Xanax
Calm the mind and lead us not into day drinking
Forgive us our craving for the productivity of cocaine
Ritalin this Batman
Speed our inattention away
For twenty, fuck it.

One step forward, three steps back
I should have spent my weekend working two 8 hour shifts. Instead, I spent it mostly building pipes to replace the rusted out galvanized steel pipes from the kitchen to the basement and snaking the cast iron pipe in the concrete foundation.
Good news! In the end, I was able to run 8 gallons of water through the pipe.
Bad news. I have no idea where the water went because it never made it to the sewer cleanout just outside the house. Well, I know where it went. It went into the ground because the pipes have collapsed and the plumbing snake came back with clay all over it.
I really need a month dedicated to working on my house. It would help if I could bring in a 20 foot shipping container for storage of stuff in the house as well as building supplies. It would doubly help if I owned a truck or SUV and put new wheels on my trailer. All of this needs to happen in the next 3 weeks which perfectly coincides with an absolute overloaded work schedule that will have me working night and day. And of course, they sold my $1.3billion lottery ticket to someone else…again.

Those colloquialisms
Sometimes words come out of my mouth and I’m not sure why, where they came from, or if I could even define them. Today? “Humdinger”

Is it a duplexer or diplexer that I need to work satellites with one full duplex dual band radio?
Ok. I think I just answered my own question by actually reading the article the following quote is sourced from. I’m going to post this just in case others have the same question.
TL;DR: Duplexer is the answer.
Diplexers separate signals based on frequency, whereas duplexers separate the transmit and receive path of signals based on their direction.
Source: https://resources.pcb.cadence.com/blog/2023-diplexers-vs-duplexersThe Venn diagram in the above source really brings it home. “Duplexers separate the transmit and receive path of signals based on direction”
My confusion started as I was googling around and found this Reddit thread: https://www.reddit.com/r/amateurradio/comments/eq7tal/do_i_need_a_duplexer_for_satellite_work_with_a/ with answers in both directions.
OP asked “Do I need a duplexer for satellite work with a full duplex radio?”
Answers included:
“devices meant […] specifically for separating HF and VHF/UHF”
As the terminology is commonly used, that is a diplexer, not a duplexer.
Then another support for diplexer:
A duplexer (the english speaking world) is a device to combine or split RF paths for a specific frequency, generally in the same band and traditionally use cavity filtering to accomplish this. A diplexer is a device to combine or split frequency ranges of different bands and typically uses a LC filters. The designs come in arrangements of low pass/high pass (diplexer), low pass/band pass/high pass (triplexer), and various low pass/band pass/band pass/…/high pass designs (multiplexers).
The reason you see duplexer often (mistakenly) used in place of diplexer…has to due with the lack of the specific word in the language used in the country the product was manufactured in.
Then the contradiction:
Yes. You need a duplexer to send 70cm to the 70cm side and 2M to 2M.
Along with a link to build duplexers: http://k0lee.com/duplexer.php
And finally, a suggestion to buy a diplexer.
You need a diplexer. Get an MFJ-916.
But the MFJ-916 isn’t a diplexer. It’s a duplexer. https://mfjenterprises.com/products/mfj-916b
I feel like many people are misusing these terms.

It’s about the journey
Oh to imagine where I’d be had I stayed on the path. Walked the line. Followed the rules.
But then, would I have had this most excellent adventure?

S.M.A.R.T. Goals – Achievable vs Attainable
S.M.A.R.T. goals are often interchangeably written with the A as either achievable or attainable.
Attainable is wrong.
Achievable refers to something that is capable of being accomplished, while attainable refers to something that can be reached or obtained. In other words, achievable is about possibility, while attainable is about accessibility.
The Content Authority – https://thecontentauthority.com/blog/achievable-vs-attainableWhen defining goals, you are looking to remove ambiguity. Therefore the A needs to be achievable because we are interested in assessing whether or not the goal is possible. If it is not possible, then we have not written a clear goal.
S.M.A.R.T. goals are a way of setting oblectives that are clear, trackable, and achievable. S – specific; M – measurable; A – achievable; R – relevant; T – time-bound
