funniest QSO ever!

Posted: 22 Apr 2022 04:05 PM PDT https://www.reddit.com/r/amateurradio/comments/u9rbj5/funniest_qso_ever/


Ok I just Had the best (facepalm) QSO ever. This dude was calling CQ on
20m, I won’t give his entire callsign but it contained an H, He used the phonetic “ Jalapeño” ! At first I thought it had to be a joke but he seemed
oblivious. I had to explain it to him. submitted by /u/moesentme

PSA: buy and learn to use a manual tuner

Posted: 22 Apr 2022 06:57 PM PDT https://www.reddit.com/r/amateurradio/comments/u9ulj2/psa_buy_and_learn_to_use_a_manual_tuner/


it is absolutely amazing. went from being able to tx 2 bands to being able
to tx 7 bands. its really really really great for hams who have limited
space to put up an hf antenna like i used to be. the radios often have an
auto tuner built in but they cant help at greater than 3:1. submitted

W6SFM On-Air BUG ROUNDUP

Posted: 22 Apr 2022 06:03 PM PDT https://www.reddit.com/r/amateurradio/comments/u9tl9k/w6sfm_onair_bug_roundup/


Announcing the W6SFM On-Air BUG ROUNDUP
The Samuel F. Morse Amateur Radio Club -- a CW enthusiast club based in Sacramento, California – invites you to a special time bringing bug
operators together on the air. This 24-hour event is not a contest; rather
it is a time dedicated to celebrating our CW and Bug key heritage. In the
same spirit as ARRLs Straight Key Night, participants are encouraged to get
on the air and simply make enjoyable, conversational CW QSOs using a Bug
style key as the sending instrument. There are no points scored in this
event, and all who participate are winners.
This is an opportunity to exercise, share, and exhibit your personalized
fist. Amateur radio operators of all ages and levels of experience are encouraged to participate. There is a very easy and quick registration form found at https://w6sfm.com/bug-roundup/ (registration is optional). Once
youve optionally registered for the event, simply Call "CQ BR" so folks
know you are a Bug Roundup participant. Grab that bug, clean those
contacts, and let’er fly! We want to hear that “Banana Boat / Lake Erie Swing" or that commercial KPH/WCC quality fist.
Reserve the date! The event begins on May 22nd 00:00 UTC and concludes
Sunday May 23rd 00:00 UTC. Thats 5:00 PM Friday evening until Sunday 5 PM Pacific Time
For more information, to register your station, or to help in spotting (potentially increasing QSOs) an online chat link can be found near the
bottom of the Bug Roundup homepage located at
https://w6sfm.com/bug-roundup/ (the link will go live when the roundup
starts). Once the event has concluded, optional logs may be submitted to
the W6SFM through the link on the Bug Roundup web page.
We hope to hear you on the air!

Did I luck out with DMR?

Posted: 22 Apr 2022 03:21 PM PDT https://www.reddit.com/r/amateurradio/comments/u9qdwj/did_i_luck_out_with_dmr/


I had seen people talking about the complexities of getting DMR radios provisioned and working and Im trying to figure out if Im not done yet or
if I misunderstood.
I registered my callsign and such with the radioid and broadlink nets, got
my DMR number, found a repeater, and Ive made a few parrot calls and Texas group contacts without issue.
I did run into a very weird issue with my Anytone programmer though.
Initially everything worked great reading and writing to the radio, but I
ran into an issue where edits were not being reflected in the radio so I
had to wipe everything and start with a blank slate to resolve that.
So is there anything left to do or just go explore TGs and make friends? submitted by /u/kodack10

On 14.225 USB on an online sdr I heard a station from Rome Italy very clear
but nothing on my actual radio, but I was able to hear the other ham radio operator answer his CQ on my radio? How can I fix that I’m using an end fed wire antenna and about 30 feet in my trees is about as tall as I can get it easily? submitted by /u/Routine_Watercress76

Is it Possible to Send and Receive Email over Winlink with Mutt?

Posted: 22 Apr 2022 06:38 PM PDT https://www.reddit.com/r/amateurradio/comments/u9u8pm/is_it_possible_to_send_and_receive_email_over/


Is there a guide to setting up Mutt) on a Linux box so it works with
Winlink over RF? Ive looked but I havent found anything especially useful.
Im still getting used to Winlink and Ive only used the Windows client, so please forgive me if Ive missed something in the documentation. Thanks! submitted by /u/s-ro_mojosa

My HF noise floor is pretty high. Would a low pass at 30mhz help that? if
so, wheres the best place to buy them that can handle some power?

FT-101 Extender Cards

Posted: 22 Apr 2022 05:12 PM PDT https://www.reddit.com/r/amateurradio/comments/u9sm6q/ft101_extender_cards/


I was wondering if anyone had a good line on some FT-101 extender cards?
The only place Ive found is eBay. The price is okay at $95USD for the set,
but I was hoping to find something better.
My second question is whether they use standard board edge connectors?
Some more googling for me tonight, but if folks can get me pointed in the
right direction ahead of that, much appreciated! submitted by

[OC] The art of troubleshooting the digital world.

Posted: 22 Apr 2022 06:00 PM PDT https://www.reddit.com/r/amateurradio/comments/u9til4/oc_the_art_of_troubleshooting_the_digital_world/


The lure of digital modes and the opportunities they bring are enough to
tempt some amateurs to begin a journey into integrating their radio and computer to make a new world come to life. This isnt without pain or
challenge, but the outcomes are so enticing that many embark on this
adventure every day.
As a person who has made this trip its heart warming to see the joy writ
large on the face of an amateur who makes their first FT8 contact on a home brew wire dipole rigged together on a Sunday afternoon to take advantage of
the latest opening on the 10m band.
On the flip side, its heart breaking to see an amateur falter at the first hurdle, attempting to make their computer talk to their radio and giving up because it just wont work. At first this attitude bewildered me in a
community of experimenters, but over time Ive come to understand that
sometimes an analogue approach isnt suited to the digital world. There isnt really a place where you can attach your multimeter and see why the serial connection isnt working, nor is there any universal document that can walk
you through how to set things up.
So, for you, if youre in a place where youve all but given up, let me see
if I can find words to encourage you to keep trying. Ill skip the
propaganda about going digital and move straight to making it work.
This might come as a surprise, but in the digital world, things are built
in complex layers of interdependence. Said in another way, using an
analogy, to turn on a light you need flick a switch, which depends on power
to the switch, which depends on power from the fuse box, which depends on
power from the street, which depends on power from the substation and so-on.
If you flick the switch and the light stays off, you need to figure out
which part of the chain failed. Did it fail at the bulb or at the
substation? If the street is dark, do you need to check the fuse box or the bulb? Thats not to say that either, or even both, can also be faulty, but theres no point in checking until the street has power.
From a fault finding perspective, the number of variables that you have control over, in the case of a light bulb not switching on, is strictly limited. You can control the bulb and the fuse and in most cases thats
about it, the rest of the chain is outside your direct control.
In attempting to make a computer talk to a radio you can be forgiven in thinking that the level of complexity associated with such a trivial task
is just as direct and straightforward. Unfortunately, youd be wrong. Its
not your fault. A popular slogan "Plug and Play" made people think that computers were easy to use and control.
The truth is a far darker reality. One of the hidden sources of frustration
in the digital world is the extreme level of complexity. In our quest to standardise and simplify we have built a fragile Jenga tower of software
that can collapse at any point. Most of the time this is completely
invisible but that doesnt cause it to be any less real. Computers are
simple, but only if you control the environment. And when I say control, I
mean take ownership of each change.
Updating the operating system? Installing a new application? Adding a new peripheral? Changing location? All these things, innocuous as they might
seem, can fundamentally alter the behaviour of your environment.
As an example, consider the location of your device. Lets say that you
changed the location of your computer, either physically or via a
preference. All of a sudden your Wi-Fi network stops working. The one that
you used for years. Turns out that changing location changed the Wi-Fi
driver to stop using a particular channel, not permitted in your new
location. If youre curious, this happened to me last week.
The point being that troubleshooting is about controlling change in that fragile environment.
So, when youre trying to figure out how to make your serial connection
work, you need to stop fiddling with everything all at once and change one thing at a time. Discovering the layers of dependency makes this difficult
at times, but not impossible.
For example, a working serial connection requires that both ends are
physically connected, speaking the same language at the same speed. That depends on the radio being correctly configured, but it also depends on the computer having the right drivers installed. It also depends on the
software youre using being configured correctly to talk to the right serial device and the operating system giving your software permission to do so.
It depends on the software using the right radio mode and it depends on the radio being switched on.
Now, imagine the serial connection "not working".
Do you check the radio mode before you check if the radio is turned on?
What about the physical connection?
When youre troubleshooting, you cannot just look at the error message on
the screen and follow that path. You need to ensure that all the underlying things are working first. You dont check the bulb until theres light in the street. Same thing. No need to worry about the error until youve discovered that the radio is on, the cable connected correctly, the driver installed correctly, the speeds set right and the mode configured properly. If and
only if thats all correct, then look at the error.
This becomes harder if it worked yesterday. What changed between then and
now? Did your operating system do an update? Did your radio forget its settings? Did the cat jump on your desk and dislodge a cable overnight? Is there an earth fault that caused the serial connection to cease working? Sometimes, despite your best efforts, you cannot find the problem.
At that point you need to take a step back and think about how to prove
that something is working in the way that you think it is. Multimeter to a light bulb to check continuity - style. In the case of a serial connection, what can you use to test the link if your favourite tool doesnt work or
stopped working suddenly?
Ive said this before, but it bears repeating, since its not obvious. Troubleshooting is all about discovering and controlling change.
Pick one thing to test, prove that its correct, then pick the next.
Eventually youll come across a "Duh" moment. Dont sweat it, weve all been there. Now do it again!
Whats your best troubleshooting moment?
