Hi Paul, I saw you were spotted by VK7DIK. My working conditions are similar to yours (1W to low OCF dipole) and he spotted me too. Season seems to favor north/south paths on low bands. 73, Yan -

Thanks for the reminder Hans. I was just thinking ‘I wonder where my order has got to’. I guess I have a few more days to wait . I (and I’m sure most people here) understand and don’t mind

Good evening all A quick note about the shipping. Orders are normally shipped the next business day after they are received. The exceptions are: 1) When a huge volume of orders are received

Thanks. I was was heading in that direction, but thought I'd ask. Up here in the puckerbrush of Maine Radio Shack knows cell phone and almost nothing else, so I've got to order online !

Hi Frank, I used a separate 3.3v reg to supply pins 4 and 5 directly. no resistors were used anywhere on the gps unit. Pin 6 is pps and pin 2 is txd. Pin 3 is earth. Hope this helps. 73's De

How do you handle the additional 3.3VDC for the UP501 ?

I was surprised last night when no one on my continent copied my WSPR signal but I WAS copied for about an hour in southern Australia! 13360 km per watt on 80 meters I will take any day!

Just received my version 2.02a 20 minutes before heading off to work. Can confirm the unit fired up first time with gps working and calibrating the output. No fuss and no hassle. My gps is the UP501

On randomness and antenna length, I generally try to ensure with loops that they are at least a full wavelength long on the lowest operating frequency. If that is achieved you can tune them on that

Must have been a few oddities in previous tests with the U2 on 28Mhz. Now that I've moved mine up into the attic, and walked a mile away to do some listening tests using the FT817 the signal is as

Try it and see how it works Tony. As if often seen, random bits of wire work better on some bands rather than other, depending upon the distances in the doglegs etc etc. Sometimes results are

On the matter off loops, I am thinking of running wspr on two frequencies simultaneously and am planning to make an invisible horizontal loop of fine wire using the mountings for my plastic gutters to

Thanks, Andy, At present, I have a wire loop that goes all round the loft, following the pitches of the rafters. I'm always looking for ways to improve things, and you have given me a few

Hi David, It's nothing special at all - honest. It's a pure 8ft square loop which is fed at the bottom centre via a suitable matching unit in order to transfer as much power into it as possible

Hi Andy, Can you share a bit more info about your loop and its tuning? Especially for the lower bands. Best Wishes David G8XBZ -----Bits of Original Message----- From: QRPLabs@...

Hi Hans, Joking aside, I must admit to being drawn to your website some time ago as I was looking at stuff for various interests of mine. The valve tx being one, but it was more the NBTV stuff that

Kits for them next week then ? ;-)

Hi Andy Glad it's working so well! For those who are interested: the 1-valve TX is here: http://www.hanssummers.com/cwtx.html The receiver and ATU were also homebrew

Just for info,I've had the U2 and the UP501 module on ever since I got the beta chip in and never switched it off in the last few weeks. It's never skipped a beat! Today was the first time I'd

Do you mean that it starts high and then a few seconds later it drops ? Or do you mean that the higher the frequency = lower output ? With 3x BS170 @ 9v you will typically see:- 1.1w to 24Mhz 650mw
