The Ham Radio thread

It’s a Diamond X200 dual band antenna. It’s omnidirectional and can be used in the 2 meter band (144 MHz to 148 MHz) and the 70 cm / 440 MHz band (435 MHz to 450 MHz).

Out-of-the-box, the maximum frequency the radio can transmit is 450 MHz. I modified the radio so it can transmit up to 470 MHz. I thought, “Cool! Now I can use it for GMRS communication!” And it works well for that. But then I later learned that, if you want to transmit on a GMRS channel, the transmitter must be approved & certified by the FCC for GMRS communication. So even though it works on GMRS, I am not allowed to use it for GMRS. I am now looking to buy a dedicated GMRS transceiver that is certified by the FCC for GMRS communication.

Yes, the 7300 isn’t cheap, but there was both a manufacturer’s and store rebate (IIRC $100 each) plus I sold my old rig (Kenwood TS 140S)
There are probably good last generation rigs out there for a decent price.

New ham here. Passed technician and general exams the same day- there’s lots of overlap in the questions. I started with a Chinese 2meter/70 cm walkietalkie (handitalki) for less than $75. Made contacts immediately once I got the danged thing programmed. ( ‘Chirp’ is your friend- look it up!) It took about a month toget a 40year old Kenwood TS 440 on the air. That is ok for DX and local contacts. Great fun messing with antennas and making those first contacts!

Hang in there! Lots of nice people out there, (and just a few wackos). Ham radio has people of all ages and both sexes involved. You will learn things and make friends. Can’t beat it with a stick!

As did I! Sorry funny–I went in only intending to take the technician exam. I passed the test easily, and it was early–and the guys running the session asked: hey, if you have some time, you can try taking the general exam. $15 later, I take the exam–and fail. But they tell me I’ve only missed by one question, which I suppose isn’t bad for having only studied for the technician exam (as you say, there is overlap on the questions, but not complete). And it’s still early, so I can try again for another $15. That time I passed!

All that said, I’ve only ever used the license for a high altitude balloon launch, using homebrew SDR software for reception.

Unless they offer me a new contract, I will be forced to retire in a few weeks. Getting my ticket is on my bucket list.

It appears (according to google) to be constructed from 5/8 wavelength vertical elements and, as expected, is matched to a 50-ohm feed line.

That’s when I did it, too.Being retired is fantastic for about 6weeks. Then you need projects or you go crazy.

Oh man, the 7300 is a great rig, and one I’m considering buying, but like any good hobby, the possibilities to spend money are endless. Here’s that IC-7300’s big brother.

Be ready to part with more than 12 grand to play in that league.

I’m (mostly) content to live in the DMR world. I can punch in talk groups on the local repeater that let me talk to people all over the world just using an HT (and some internet ‘cheating’ on the back end of the repeater). If I do get an HF radio, it will be to play with FT8 and other digital mode fun.

I had also intended only to get my technician ticket, but realized while using the Hamstudy site that the question pool was so small, it was the work of a couple evenings to just memorize all the questions and answers. The extra question pool was enough larger that I knew I couldn’t do that the same way. So I went on test day and passed technician and general in just a few minutes (doesn’t take long to fill out 20 circles), then took a crack at extra. I came real close, but in the end couldn’t quite pull it off as that test required some actual knowledge I couldn’t extrapolate from the memorized questions.

I did get some admiration from the hold guys administering the test because I showed up with a slide rule for any math I’d need to do. The only calculator I could find was my phone, obviously verboten in that environment. And I needed something that I could do logarithms with, and conveniently I still remembered how to do that on a slide rule.

Oddly today I was bragging to one of my (younger) teachers about my age. I told him I knew how to use a slide rule. He had honestly never heard of one.

It cannot replace all the expensive hardware, but if you do like cat whiskers and valves there is GNU Radio software that allows you to wire up blocks for arbitrary signal processing. Plus you can experiment with weird modulation and experience 7G or 8G digital modes today!

I’m a ham and, like many others, my interest and, interests within the hobby, have waxed and waned over the years. I started out heavily into public safety Motorola gear which was not easy to break into in the mid-late 90s. There was a lot of pirated software to acquire and grey to black market radios to sniff out. Cool crypto stuff, though not allowed on ham bands, it was around.

Then, I shifted to commercial HF rigs, especially those capable of embedded Automatic Link Establishment / ALE, a digital mode which can help determine the best band for a certain location and time of day. I have several different Motorola (which Ma Moto spun off, first Mobat, then Elbit) Micom HF rigs, some with pretty rare but awesome autotuners, very important for ALE use. I picked up a neat Barrett 2050 along the way, though it doesn’t have the ALE option flashed.

Then, I got into some green radios: military HF manpacks. Modern rigs are ultra rare and, since you’re trying to bid against literal mercenaries, cartels, paramilitaries & militias, the prices are astronomic. I lucked into finding one that was $$ when it should have been $$$$$^3. Someone from Sweden told me my particular rig was $70,000 new. 1.6-60MHz, embedded ALE, GPS, all sorts of other data modes, silent autotuner, waterproof & airdroppable, the works. Even the batteries are cool.

I’ve been to Dayton about half a dozen times though not for the last 5-6 years. I was able to check into three nets with my sweet manpack: one each on 80, 20 & 6 meters. And who wouldn’t want to hang out with guys like this (That was from the 6 meter ‘Cold War’ net/eyeball QSO in 2015)? Watch out for those storm clouds with those antennas! I met up with another doper at Dayton years ago, forget his username & call, oops.

However, while a lot of this has happened in the last ten years, my true interest during that time has been QRP SSB. The only rig I have that is marketed to hams is my trusty Yaesu FT-817ND. It is 5 watts maximum and I don’t use an amplifier. It’s like the power of a nightlight. My antenna is made of scavenged CAT-5 strung up as a dipolish in my attic rafters, perhaps a 30 foot span overall. I rely heavily on favorable solar conditions which haven’t been so good for a while now. But I have a few confirmed ‘1000 miles / watt’ contacts which is truly amazing in any case, especially since I don’t have a beam antenna. The guys on the other end probably do but to think of how little signal squirts out my radio in many directions, I still find it amazing.

To OP’s question, if I lost it all and had to build fresh, I’d really consider some of the new Chinese stuff that’s been developed lately. The Xiegu G90, for example packs quite a bit into a sub-$500 rig. Remote head, built in autotuner, colorful display, respectable 20 W output. I think more attention should be paid to the antenna but you can’t really study what works for your particular situation without a radio.

Well hell. I wish I hadn’t seen that.
