Dutch expat now hamradioactive from North East PA. I was first licensed in 1985 as PE1MBI but didn't really become active until the late 90's as KG4ECV and now KR1ST.

I'm interested in more things than can be explored in a single human lifetime.

Yesterday I completed the initial setup/config of my TH-D75A. I hit a snag with the RT Systems s/w import of the memory files and another with getting APRS to beacon and work properly. But I was able to debug both issues and now things are working as they should... Pretty soon I should be able to start investigating the many new-to-me features.

TH-D75A, debugged and up and running, with APRS working and I can reach my local repeater.

@croyle @wd9ewk Did you notice on the same page where you download the FW they also posted an in-depth manual in May. It's at the bottom of the D75 list. It has some good tips.

@croyle @wd9ewk Wow, this is cool. Before the FW update I used Kenwood's Memory Control Progam to load all current settings and saved it as a backup. I did it again by exporting all the settings to the uSD card. Then I updated the firmware and did a full reset. I then loaded the settings from the uSD card and it restored everything, including the current operating parameters, like which bands and memories band A and B, including VFO's were turned to and the KISS 1200 that was turned on.

@croyle Interesting. I hadn't considered that option/feature of the RT Systems software. I have it for the IC-9100 so it's not that I'm unfamiliar with it. I need to check into that. I usually don't use memory channels except on HT's and scanners of course, mostly because I don't have the patience to program them. 😃

@croyle Congrats on your new rig! I'm sure you will have a lot of fun with it. I know I do. It's such a capable little rig. I don't use the RT systems software with it, just the free Kenwood stuff. Please share your findings and the cool stuff you learn about this radio and how you use it!

@kr1st@mastodon.radio avatar

@croyle I saw that @wd9ewk posted about the firmware update and then promptly forgot about it. I forgot if the Kenwood software stores all the settings. That's the only software I have used so far. Thanks for reminding me about the firmware update!

kr1st,
@kr1st@mastodon.radio avatar

@croyle @wd9ewk Then I did the same thing after another full reset using the MCP software and it worked the same way. Everything was restored as if I never touched the radio.

So if you don't want to use the Kenwood software, you could still use the uSD card option to save and restore everything.

Remember when the internet was fun and new?

Usenet
Gopher
FTP
Telnet
IRC
Netscape Navigator
Cisco Routers where cool and not just overpriced junk

I offer equal time for an opposing view.

@HopelessDemigod I think it was indeed FidoNet!

That article about Shortwave 2.0 made me think of this idea that was once floating around about broadcasting a lot of data in a cyclical format, like Teletekst on TV's in European markets, where you can select a page number (say WX info page) on your receiver, and as soon as that page was transmitted your receiver would pick it up and display it. Of course your receiver could cache all the pages if it had enough memory available.

@kr1st@mastodon.radio avatar

@HopelessDemigod What was that dialup network called that worked a bit like Usenet where you would download pages of posts of subjects you subscribed to? You could write your own posts and responses and once you uploaded them it could take a long time before it was distributed because all these servers had to call each other and exchange data. I can't remember the name of it. It was kind of precursor to the Internet.

I decided to re-enlist (heh) in the . There are small but positive signs of progress there, and I figure that they probably dismiss complaints/observations from non-members out of hand... My hope is that they step up and show some actual leadership with regard to politics, diversity, hate speech, etc. It's a ridiculously low bar but it would be a further step in the right direction.

@VE2UWY @croyle I agree, LOTW is a terrible implementation of a hamradio activity (award chasing) that they tried monetizing on.

They should have gamified it. It's a perfect candidate for it. But no, they made it into a boring laborious product that soon no one will care about, if they're not careful.

QRZ.com seems to understand this. You log a Q, can check immediately if qualifies for an award. If it does, bam, another badge on your profile. It's all about badges these days, baby. 😄

@tsherrygeo @ai6yr
If you attend a college or university in the US, or work there in any capacity (as long as you have access to a .edu email address), your school may be offering a free unlimited digital subscription to the NYT and WSJ apps. Check with your school's library or do a search in their portal for a link to these services.

I know my employer does and happily use those services. 😀

@ai6yr I made 59 6m AU SSB Q's. It was nice to see 6m packed with CW and SSB signals for a chance as AU renders FTx useless.

I'm visiting family in Indiana. When they asked what I was teaching this semester, I told them about the doc course I teach that is about quantitative research within a Critical Race Theory framework. I could almost see some heads exploding 🤯 I explained to them that I couldn't teach that course if I worked in Florida or Texas, and that may be the case in Indiana in the future based on the latest legislative efforts here.

    Santa brought me Quansheng UV-5k(8). A YTer in a recent video said he couldn't recommend this HT because it was "dirty" and showed a screenshot of TinySA Ultra from which the viewer was to infer that the radio was not satisfying FCC requirements.

    The FCC requires harmonics to be 40dB down from the fundamental and the video showed that the second harmonic was "only" 38.8dB down. I'm including a screenshot of that video.

    Time to do some measurements!

    Keep an eye out for Aurora Propagation (AU) happening right now.

    Here is a sound sample I just copied from NA2O calling CQ on 6m (50.102). Note the raspy CW sound.

    My antenna was pointed at 330 degrees. NA2O is due south from me and I would normally not copy him.

    I can only laugh when a YT reviewer or influencer says that the cameras on a particular phone are not impressive.

    I took this photo last night through a double pane window with the phone supported on the window sill. I'm no photographer, but color me impressed that a phone with a camera and sensor that can fit in less than a cubic cm can take a picture of the moon like this.

    It also transmits SSTV:

    I continue to be impressed by OpenWebRX (Plus). I just added a discone antenna to the RSP2 that my OpenWebRX instance is using, in addition to the active HF loop antenna. I'm currently listening to my hotspot that is streaming BM TG 204 DRM on 70cm.

    Now I can listen to my hotspot on my phone from anywhere. Tell me that's not "real" hamradio. 😂

    I went nuts and set up 40 profiles covering 500 kHz up to 1.3 GHz. Now on to setting up bookmarks...

    With the last two Q's on 17m with ZD7CTO and VK3GJG just before midnight EST, it makes it official. Today I made 180 QSO's on every HF band from 160-10m running 100W and a wire.

    Since the autotuner is still waiting for a relay, I broke out the trusty (if you can say that about an MFJ product 😁 ) MFJ-949E manual tuner for this exercise. 😀 Worked a bunch of POTA stations on SSB and also worked a lot of stations on FT4/FT8 as well.

    I consider it a well spent Saturday afternoon and evening. 😁
