Cool radio, I fondled it at the fest :gay: any plans for an antenna?

I still need to get some sort of VHF/UHF rig in the house. Right now i'm looking at ic-706mkiig's since it will be useful even if I get a ic-9700 or something cool down the road. I'm looking into building a tripod mounted satellite tracker for the next project. Besides getting my station from trash to decent level (Johnny gonna help me with that I hope)

I have one! It's hard to see in the photo, but I have a 40m hamstick mounted on my balcony. So far I've been receiving CW and phone signals from up to a few states away which isn't half bad!

You guys aren't going to believe this, but that guy is our games teacher.
I've finally decided to get a ham radio license (hi Jonny :wave:, the Z-Cast belatedly inspired me (I was the guy constantly complaining about being in a basement apartment in a valley, and I still am, so I'm just going to do handhelds for now)). I've run through both the Technician and General exam questions on hamstudy.org and I'm feeling pretty confident that I at least know where/how to study for my weak areas... except for questions related to antenna theory/design which I have pretty much no background in. Does anyone have any good, beginner-oriented (and preferably free :v:) resources I could use to study up on antennas, at least to the level of proficiency needed for the General exam?

Before the exam, cram cram cram, don't worry too much about actually learning anything but maybe take notes for later. I remember the General having stuff about atmospheric layers and propagation that caught me up in particular.

For after the exam, I've found the most useful stuff to be in books:
- ARRL antenna book is pretty much the benchmark for antenna information. Worth checking if there's a library nearby that carries it. It doesn't change much between editions.
- I really like Practical Antenna Handbook (Carr/Hippisley), it has things neatly divided into sections by antenna type and also includes gif information about actually hooking things up, grounding, diagnosis methods and tools. I actually like this one more than the ARRL antenna book.
- I think there's also an ARRL "antennas for small spaces" that's supposed to be good? I've heard the catch is that "small spaces" is relative and just means anything that isn't traditionally measured in acres.

Those look pretty neat, I might grab one for a portable/camping kit. I'm also now on 40m's and all the other bands, although not very well. Put up the CHA-250b, its pretty conspicuous. I'm sure the neighbors hate it. Nice living in a place with no HOA though.



It's also coming down soon, It's not quite a safe distance away from a couple of electrical supplies to the neighbor's and our house. I think I'll put a Diamond X300A on the mast and also use it as a tie off for a long wire type deal to the tree in the back.

If anyone wants to try some 40m SSB tonight or tomorrow let me know :)

Yeah, that's how qrp rigs work. you're paying for miniaturization and portability in place of PEP. Besides, think about hucking a 991 around on a backpacking trip with enough batteries to run it for more than five minutes at 100 watts. It's gross. People try, then they fail, and then they buy a purpose-built QRP rig.

this isn't made to be a shack centerpiece, it's meant to live in a Jansport alongside a hunk of wire and a logbook for your day hike.


Pimblor posted:

My pessimistic guess, being a 7300+9700 koolaid drinker, is $1499. I've already heard rumblings that I might be high, though. If it comes in anywhere below 1200 bucks i'll be amazed.

(my 9700 guess was $2500 and placed my preorder at $2099, HRO ended up knocking it down to 1899 because i prepaid on release day)

705 flyer translation is out

https://twitter.com/JO1NLP/status/1168148315419987968

further thoughts:

- rumors that theyre shooting for ~100k yen price. A thousand bucks would be an amazing deal.
- Sounds like no internal tuner, which sucks, but I have a lil qrp tuner, i won't die.
- compatibility with ID-51 and ID-31 batteries may cause me to buy into that ecosystem too
- General coverage RX up through 2 meters means that it'll be your am and fm broadcast camp rig too, nice. Hopefully they're wise enough to stretch VHF RX through 162 mhz for NOAA weather, fatal flaw in the 817 in my opinion.
- i'm buying the drat backpack for this one. I've been hunting for the 703 backpack for a year now and they are extremely expensive.

I wouldn't hold my breath. If Yaesu couldn't be bothered to fix that after 17 years (or whatever) of people complaining then Icom probably won't either.

Yeah I am contemplating selling off mine too. I will probably wait and see what the hands-on reviews are like before I make that call. Not to say I haven’t loved my KX3 but it would be great to ditch the external waterfall and the LCD digit screen for something a little more compact.

Honestly I'd love to have the PX3 and the amp, but oh man that price. I could sell off my TS-590S and get the amp pretty easily, but there are a few things I wish the KX3 had, like manually-adjustable notch filter in SSB mode.

Oh wow, congrats! I remember being able to get tech+general in one trip after studying for both. They offered the extra and I said sure for kicks. Ended up just returning the exam completely blank because I couldn't even understand most of the questions. Eventually came back and aced it about a year later, after 3-4 weeks studying whenever I had spare time

While reading through the WSJT wikipedia article, it suggested that FSK441 can be used on the 2m/70cm band to make contacts in excess of 1K miles, but I've yet to find any examples or tutorials for this.

Other than CW, are there any non-voice modes that can readily get long distances in the VHF or UHF bands? I've got general but one of my buddies only has technician and we're about 250 miles apart.
It'd be pretty sweet for us to be able to send messages even if it was slow and required a PC behind it.

Pretty sure they are referring to meteor scatter or moon bounce for those modes/bands. There may be some esoteric propagation mode for vhf and up that I'm not aware of (or forgot) but that sounds more 6m than 2m/70cm.

Yeah thats meteor scatter land. i run 6m scatter fairly regularly and have logged one 2m scatter contact to Texas from Denver but it took about a half hour to complete - my antenna's not very high.

lots of fun though if you're into staring at a screen and sipping coffee and cranking out massive amounts of RF at 4 in the morning
