Hi,


This did go quietly by...
https://factualradio.wordpress.com/tag/tokyo-high-power-labs/


Given Tokyo-High-Power heritage & quality I can only assume BaoFeng bought it for the expertise & IP
Looks like the there could be some interesting(cheap) products in the pipeline.
It will be interesting to see how Kenwood, Yaesu and ICOM will react.?

You rarely see people interested by am radio now .

Had some nice radios when I was a truck driver , but no big am radios .

If I were Kenwood or the other ones I would start to beware of them , they have a real cheap workforce but it s nothing compared to Japanese quality or Taiwan s .

Saw a big difference between Chinese & Taiwan made cb radios .

I think you maybe surprised how many Radio Amateurs there are, obviosly not like the heydays 70's/80'.
They are at an all time high in the USA: http://www.arrl.org/arrlletter?issue=2015-03-05#toc02

I think we are in the same position like Cars when the Japanese first started to export in the 60's/70's...
Unknown & Sometimes poor quality, but look at what happened in the 80's/90's they took over the world.

I guess in the next few years the Chinese will improve and adapt.

I bought a Chinese 2M/70cm FM Handheld for 29.99 @ $45.00 over a year ago,
it's still working fine, If it failed now not exactly a big loss.
(( I actually program it from LL 2.2 with CHIRP  ;D  ))

Hey cool ! did know that you could program it from LL ! A nice surprise !  Thought ham radio was way down .

Had a custom built antenna & had /have a modded 10Meter . + loads of moded cb radios , was some great years for me !

Thought at some time to have my am radio licences but had no time about these .

There are so many facets/angles to Amateur Radio...

- Just chat away to people around the world
- Communicate/exchange messages from your PC via Radio & Digital Modes, what I'm setting up at the moment
- Broadcast TV Pictures inc HD
- Communicate via Amateur satellites
- People who launch balloons with radio transponders
- Radio Foxhunts, orienteering looking for hidden beacons
- Just building stuff

There's something for everyone... You might get to speak to somebody on the ISS

Hello!

Icom, Kenwood, and Yaesu are in another league entirely. However, they're not THAT MUCH better, and this can't help but put downward pressure on what they charge for their equipment.

The Charlotte Hamfest is this weekend. I need a good HF rig, a mobile antenna, an antenna tuner, and an HT for my bro, KF4JBF.

If I can find a compact dual-band mobile rig as well, I'll get one, if the price is right. Of course there are always the neat things you didn't go there to buy, but just happen to 'discover' while you're there.

I will also look and see what's new out there at the dealer spaces. The Baofengs and TYTs get the job done, and they ARE affordable. I have a Wouxun KG-UVD1P Handheld, which is also supported by CHIRP.

For the uninitiated, CHIRP is used to program a wide variety of two-way radios. CHIRP sure beats entering all the parameters for each channel preset by hand, which is what I have to do with my Icom IC-207H. I just cringe at having to hack a control head extension cable to make a data cable to program it, building an RS-232-to-TTL converter circuit assembly for it, and then finding the software for it out there somewhere.

If I ever DO find an IC-207H extension cable for sale, I'll buy two. THEN I'll take my chances at hacking one up...

Hi Rob,

Yes, the Big Three are in a different league, but time will tell.

Seems you have a big shopping list...

I have dipped in and out of radio for many years, mainly because of moving around a lot with work.
I'm now likely to be where I am for the foreseeable future so I'm starting up again.
I was looking for weeks at what to get, "The Big Three" and at the New SDR type radios.

In the end I decided on an "ELAD FDM-DUO", Gives me a standalone radio, and SDR Capabilities.
If I want higher power, I can always add an external Amplifier at some stage in the future.
http://www.eham.net/reviews/detail/11933

It's working very nicely with FLRIG & FLDIGI on LL2.2
I did initially have an issue with USB/CAT port till I found I needed to:
Code: [Select]
sudo usermod -aG dialout username
I'm going to give WSPR a try over the weekend

GL at the Hamfest, hope you find what you want.

 Icom 207H pgm  cable adaptor I made one years ago , there are schematics on DKMODS  , the guts of it are in a small box, since then I have added other output cables  using junk rca jacks. I would go back and change out put to an RJ45 or a serial 9 pin d connector , I have not tried chirp on the 207H . It works with my W32's and the Chinese UV5Rs, got a pair of those<sigh> but they wont do air band   I see that almost every thing is USB now.
I want to use an RTL SDR but, don't know how yet, the part about python P3> made go back and study how to use that.I think I have to add it to my LL2.2 first. I was going to try and use this for a spectrum analyzer, albeit, not for accuracy, there are some old machines <cushman ce50a> I have, that have YIG osc,s in them and I would like to at least be able to hear them , they are above every thing I have for test equipment now. . A friend is bringing me some dead Boafungs to play with. ,,We shall see if they are fixable . Darrell de kb5zxm

Hello!

I had to look up the acronyms, but they both appear to be quite interesting devices indeed. As for RTL SDR, I don't think the USB TV dongles I have are based on that chipset. Will keep an eye open tomorrow, to see if there's anything compatible out there. Having a SDR would be cool...

Hi,

Yes, the RTL SDR(USB Stick) is very popular.
SDR Radio's are definitely the future.

I let WSPR run last night on 17M @ 2.0Watts
This morning I was surprised at where my signal was "spotted"
I have a temporary wire antenna @ 8M long at about 5M high.!

A guess at some possible country links:

USA: http://www.arrl.org/
UK:   http://rsgb.org/
NZ:   http://www.nzart.org.nz/
AUS: http://www.wia.org.au/

If you are interested you should be able to find info on:

@ altman,

If you intend to transmit, yes you need to pass various tests/exams.
Not sure how complex they are in Canada..??
Most countries have some form of entry/novice level tests/exams.

There should be info & contact details here: https://www.rac.ca/
