Hi

I guess it fits there: I was a bit frustrated by my FT-450D because of its lack of waterfall display when I was a listener. When beginning the hobby I was on 11 meters, and listening on 10 to 12m, didn't want to spend more than that, but I already knew that hacking your hardware was part of the fun...

Now it's fixed, more like hacked ;)https://toobnix.org/w/qkkH3wsSNC4cGT4Sccsaj4

Using an RTL-SDR that was sitting on the shelve, and a 60€ IF card adapter, it's a whole new thing!

Maybe this will encourage you to upgrade this nice and affordable transmitter, use it more and pass your exam ;-)

Kind regards F4IPZ

What cool stuff is going on with IP over ham radio? I want to build simple services accessible to other hams in my area, and would love to learn about what's out there.

  • New Packet Radio: This looks pretty cool, although until the FCC makes a decision on updated VHF/UHF bandwidth and symbol rate restrictions, I'll hold off on buying any dedicated hardware

  • Broadband HamNet: I'm not sure if there's any existing network in my area. Since it's 802.11 with yagis and amplifiers, I feel like you'd need a good density of local users for anything cool to develop.

  • AX.25 with TCP/IP: I might play around with this. It doesn't require equipment except a UHF/VHF radio, antenna, and a computer, so it might be easier to convince others to try it too. Obviously you're very limited in bitrate, but it would be fun to set up a gohper hole or a BBS.

Are there other technologies or projects worth looking into? Even though I'm not personally interested in buying new equipment for it, I'd still like to hear what's out there.

I'm really intrigued by digital modes. Stuff like JS8Call seems really cool, and I want to get into it.

I don't have any HF equipment. SSB isn't very interesting to me, so I was thinking of getting a digital-only transceiver and saving some money. I think it would be cool to take a small QRP box with a laptop or raspi, and do digital mode Pota with it.

I've seen the QDX which looks exactly like what I want and seems to get good reviews. Any others that I should be aware of?

I'm just getting into ham (my technician exam is tomorrow night), and I'm looking for ideas on starter kit.

For now, my interest is in making contact with a friend who lives ~10 miles away, as well as other amateurs in the county (there's a repeater ~2 miles away). This friend needs to reapply for his license, but he has a mobile 2m/70cm transceiver from his old call sign. Eventually, we'd like to get into digital communication between our houses.

Even further down the line, I think long distance HF sounds cool, but that looks like a money pit I'm not quite ready to dig just yet.

I don't want to set up any crazy antennas just yet, as partner and I are house hunting. This also means we could end up more like 15 miles from my friend, depending on what we find.

I was wondering if anyone here could suggest beginner's equipment for my goals. I'm ok to spend a bit more on systems that are still useful if my interest in ham expands beyond these initial requirements.

Hey ham heads - Was/is anyone using SMSGTE with APRS? It appears the service is currently down due to regulatory issues. If so, is anyone aware of an APRS to phone SMS gateway alternative?

tnx es 73 de w4luc

Would the perfect title for the blog post I hope exists somewhere. I, like a few other posters, just grabbed one of these things. I also took the step of reading through a good chunk of Ham Radio For Dummies just to get a handle on the basics.

  • What can I (legally) do with this thing without a license?

  • Any pointers for learning the basics on this particular machine?

  • I should read the manual cover to cover, right?

  • Looks like it's easier to program from a computer, any tips on that?

Hey Everyone,

I got my license (General) a few years back and have played around with short wave a bit but wanted to start to get more into the FT8 side of things. Does anyone have a low cost introduction to FT8 or even some good resources to start to learn more about it?

It's nice, looking at a computer screen outside for a change :-)

Hi -

I have a Yaesu FT-70D, and I have had it for almost exactly one year now. My review is this: it's OK. It's not great, but it was also pretty affordable, as far as VHF/UHF HTs that aren't just junk go. (It normally runs about $175, but seems to go on sale pretty frequently for quite a bit less.)

First off, a disclaimer: I really only use VHF/UHF when I travel and for events. I'm not a big FM rag chewer. An HT is a tool for me, not something particularly exciting. I have a mobile radio mounted in my vehicle, and I have at times (I do not currently) had a mobile set up as a base station in my home for either voice or digital traffic, or both.

As far as positive features, the FT-70DR is a very comfortable size, has a very serviceable loudspeaker, and the transmitted audio quality is reportedly good. It does have Yaesu System Fusion (although I've been able to exercise this very little due to lack of convenient local support). While there are many online complaints about battery life, I have found it quite satisfactory; I don't work it too hard, either, though. Fitments (such as the belt clip, battery pack, etc.) all seem quality and durable, and while I haven't put its IP rating (IP54; dust protected, tolerant of water splashes) to the test, it's clearly a tight enclosure.

My list of gripes is longer.

The antenna that came with it was fairly deaf; I tried a cross-town chat with a friend of mine who had an HT on a rooftop antenna, and we really struggled. After tuning around a bit and comparing signal strengths, it appeared that my reception was quite poor. I purchased a simple dual band whip from MFJ (I think it was under $30, maybe under $20?), and my reception improved noticeably. It is, of course, longer and more stabby than the Yaesu rubber duck.

It has no dedicated memories for the weather bands, which surprised me, because at least some of the Yaesu mobile radios that share its design language have this feature. This feels very unfortunate, because while the local weather stations can be entered into memories easily (it has something like 1,000 memories, you're unlikely to run out), they'll stop scans if they're included in a scan; the mobile radios have a feature where they only stop on weather stations if they're playing an alert tone, and they scan them frequently enough to catch one if it's there.

Speaking of memories, dealing with the memories sucks. You absolutely need the manual to do many things with this radio, unless you just use it all the time. I'm a "set it up once and don't look at it again until I have to" user for VHF/UHF, so when I travel (for example) I have to make sure I have the manual PDF with me, because otherwise there's no way I'll get local stations plugged into it.

Speaking of plugging memories in, I never was able to get it to communicate reliably with computer control software, despite the fact that it has a USB port right there on the side and comes with a USB cable. You have to do some ridiculous dance where you power it off, then remove the battery, then plug it into power while holding the power button, or something like that, to get it to go into programming mode. It's bonkers, and it's also unreliable. I'd blame it on user error, except the Internet is basically filled with people having the exact same problem, and then some reply guy coming in and saying it's never been a problem for him, he just has someone lend him a third hand while holding it upside down after taking it directly out of the freezer and then it works fine.

In general there's clearly never been a UX person near this radio. Changing the volume requires holding a button and turning a knob at the same time. There are rubber flaps on both sides of the radio, both of which can be picked out rather easily with a fingernail, and one of them is the control buttons but the other one is the charging, USB, and headphone ports. To top it off, the bottom symbol on both sides is related to power. Guess which one I've picked off by mistake more than once to plug in power? Guess which one is a LOT harder to get back in than it is to get out? The menus are impenetrable, and every button has three functions (push, hold, function+button) or more.

The model number of the charger that it comes with is SAD-25, because it's really sad, and it takes 25 years to charge the battery. However, if you pay $50 to Yaesu for a drop-in charger adapter, the exact same charger will charge the battery in much less time. Now, this might not completely be rent-seeking, because the cradle has a three terminal interface while the trickle charger has only two, and the smarts for rapid charging the Lithium battery might be in the cradle, but ... why?

Then there are the gripes I have about almost all ham radio equipment: why won't it accept a standard headset? Why doesn't it have support for a BLE headset, for that matter? Why doesn't it charge off a standard USB port? Why can't it charge and operate simultaneously? Using a ham HT usually feels like stepping back a decade. I do appreciate that radios like this are built to a different spec; I don't want it to have a color touch screen, or a glass back. I do, however, wish it respected the past two decades of electronic progress. I honestly feel like the Standard C-158A that I have from the mid-'90s with a Lithium battery pack would be a more ergonomic and easy-to-use radio!

In short, would I buy it again? I don't think so. I think I would buy a radio without System Fusion and with a simpler interface (these things aren't always guaranteed to go hand-in-hand), probably for a bit less money, if I were choosing a second time. Perhaps a FT-60R or FT-65R, or a competing radio from Alinco, Icom, or similar. I think I could save $30-50 and get a radio I'm at least as pleased to own, if not more so. Maybe things would be different if System Fusion had more buy-in in my area, or if I were more of a VHF/UHF guy.

One of the local radio clubs (of which I am a member) is hosting a hamfest tomorrow morning from 8 AM until we get tired (vendors welcome at 7 AM). Entrance is $8 for all attendees (vendor or browsing), vendors should bring their own tables. It will be at the Cambria-Wilson Volunteer Fire Hall on Cambria Wilson Rd. in Cambria, NY.

This is our second annual summer hamfest (we used to hold them in the winter), and last year's was very well attended. It looks like tomorrow's weather should be great, so I'm hoping for a good turnout again. We're close to Buffalo, Toronto, and Rochester.

I'll be wearing a navy LARA polo shirt with my call sign (KB8OJH) and (probably) a leather wide-brimmed hat. If you should drop by and see me, say hi!

They're cheap, poor-fidelity, horrible propagation radios with handfuls of bugs (the one I bought years ago has a lot of trouble with frequency bleed).

But they're also now less than $20 USD on Amazon.

This seems like a good community to have here since we have a large amount of interest in ham radio among SDF members. Let's discuss radio!
