Re: Video: What is SINAD and overview

Thanks, Adam.

I've heard the term before, and had an idea what it was about but very interesting to see the test/measurement in practice.

He has a great youtube channel, well worth subscribing too.

Re: SG Lab 23cm Transverter - Anyone heard of them?

Thanks Darrell, Hristiyan really does look after his customers! The good news for me is that it seems to be a common problem, so I don't feel 'too' much like a muppet driving 100w into the transverter! The other good news is it seems to be a pretty simple fix, generally two resistors, sometimes two ...

Re: SG Lab 23cm Transverter - Anyone heard of them?

Bugga, during the field day contest I accidentally ran 100w ssb into the 23cm transverter and now I have no rx or tx on 23cm :wtf: :wtf: I'm after ideas on what may have blown. The front end 50ohm resistors all check out, I'm guessing it's something further into it. Mixer maybe, seems there's no rx ...

Re: Icom IC-9700 Pre-release brochure

A little bit more info, this time from ICOM :) You'll need to run the link through a Translator. The low down, ICOM said that they are aiming for a release date in 2018 (Japan may get it in December 2018) with an approx price of 200,000 YEN - price to be confirmed in December. https://www.hamlife.jp...

Re: What's on your Workbench?

Hi All, This is my first attempt at a BPF for 13cm to try and block some of the noise I have around here. The LNA I have is the Minikits 0.05-3GHz low noise pre amp and very broad banded, and it looks like it may be overloading the front end of the radio with all the nearby wifi and other crud float...

Re: low noise solar inverters

Hi Wayne,

The SMA inverter at my previous qth, and the fronius inverter at my current qth are both rfi quiet.

They do cost a little more, but well worth it.

Re: Icom IC-9700 Pre-release brochure

I'm wary about any information emanating out of the UK. And it is a bit strange that there is no further word on the IC9700 from Icom Japan, Head Office. You would think that they would be the first to release info, or at least have something on their website about pricing if it has been announced....

Re: Icom IC-9700 Pre-release brochure

Pretty much hit the nail on the head :thumbup: It'll be interesting to see how much Australia will get it for. Some say that it'll be higher, some say it'll be lower. If it settles at around the $2800 mark after the initial rush of sales it'll be tempting. All will be revealed in February :popcorn:

Hi Tim,

We might need a good aircraft between us to make a contact, but I'll certainly be up for some tests. I'll schedule 23rd Nov in and point in your direction with the cans on :thumbup:

Hi Tim, Apologies, I was one of those VK1's you mentioned above. In the future I'll note which chat group I am using. Could you confirm that you was hearing us? We did not use 1296 that night, but was testing our 2403 setups. If you did infact hear us on 2403.150 from your location I would be very i...

Re: Icom IC-9700 Pre-release brochure

Good find Adam! My wife can speak a bit of Japanese, I'll see what she can understand. I did notice at the 2min mark that while 23cm was selected for the top VFO, he tried to change the bottom VFO to 23cm and it didn't let him(?). Does that mean that it won't be able to do true dual watch (both VFO'...

Big congrats Steve, well done! Just on the subject of running FT8, one feature which would be nice is to have it transmit once every say 10mins, rather than the standard of every 15 seconds. You may miss the very short openings, but at least it would be more appropriate to run in the background whil...

Were these decodes via long path or short path?
