Sorry if this gets posted twice - it seemed to have disappeared the first try.? I wanted to respond regarding color not making much difference in temperature.? Being a retired NASA engineer I have a

Hi all (again) Here are some thoughts about a experiment I am thinking of trying and would like peoples thoughts I have done some measurements of my current 20m OCX All using a dummy load and external

As to the plastic vs metal... I'm a strong advocate for shielding.? It does two things keep bad stuff in and band stuff out. In the simplest form that is. In too many cases in the field and even home

Robert, Most cores are non-conductive.? However if you see damage to the enamel wire it does not rule out a turn to turn short. I see that most often with two hole cores as some tend to have hard

WRT? heat... There is no one best color in the unfiltered sun.? I've had commercial experience, so a grain of salt.? ?A Kiosk project that was to be in the sun (it was solar powered) painted all

you guys mentioning USB and IQ stuff reminds me of this now discontinued kit,?http://ae9rb.com/index.php?main_page=product_info&cPath=1&products_id=8&zenid=56f7ae4cc2ee385fbd8c6c06a2531a8d -Justin

Can you get CW decoded on the LCD while transmitting? If so, then that leaves one op-amp (and stuff connected to)....IC10A. If CW doesn't decode (and the menu item is ENABLED), then everything past

Perfect. When can you take my money :) Best regards, Chris Smith M0XTE

Chris Yes. The QSX has a green/yellow transflective LCD. The backlight may be switched on or off under firmware control. 73 Hans G0UPL http://qrp-labs.com

Spot on. Most of the absorption comes from outside the visible spectrum anyway so the point on colour is moot at least from a heating perspective. From an interface and usability perspective, things

Hi All recently got my QCX working just right on 20m, i can get nearly 5 watts at 13.8v and more if i increase the voltage so very happy with it, but i was just playing around with the presets and

Hi all 1) QSX will meet regulatory requirements in all jurisdictions on all bands, if built with the supplied components and following the published assembly manual, without changes. If you modify it,

Again, looking at the second part of your message you made. Hans is not the manufacturer of the/this radio, it is only a kit. You are reponsible for what your 'buildt'. You are a HAM-radio operator.

With some expensive electro-luminescence coatings we could even have the units change color from black when *OFF*, green when *Receiving*, and red when *Transmitting*. 8-*)* _._

The idea that toroid cores might cause a short comes up fairly regularly. If you perform an ohmmeter test across most cores you will find that they are not conductive. Even if the cores are metallic,

Always fun to watch the conversations from a group of builders. And building kits from Hans has been enjoyable for years. I would like to hear from the Master himself, whether a metal case is a must

Apologies, I didn't mean to stir things up so much regarding case color - I can see this discussion is taking away from Hans' valuable time.? I will be building a QSX regardless of color, so whatever

Next thing someone may request is a color fade from maybe pink on one end and dark green on the opposite end. Might even be a tiny market for camouflage paint patterns. 8-) _._ squirrox@...>
