So now that i’m into WSPR right now, i’ve started to think about all the different possibilities and combinations I could try out with my gear to see what my receive/transmit reports would be like. Here are my results as of late, and each time I make an adjustment or tweak the system, I’m trying to gain better results. I’m pretty happy with the results given I’m using compromise antennas. So far, the furthest I have heard is 16,659 kilometers on 30 meters (Australia):
And the furthest I’ve been heard is also Australia (14,767km):
When I started researching this mode more, I started thinking that maybe I don’t want to tie up my main HF rig, as I recently read somewhere online (can’t remember where) that I shouldn’t allow modes like WSPR on a HF rig like my Kenwood because the diodes can’t deal with the long and rapid heat up cycles. This would explain the reason for the drift reports that I receive/transmit when I first turn my rig on, I’m assuming this is happening because the rig is warming up. Even more reason for me to consider the higher quality crystal oscillator from Kenwood, I wonder if it would help.
Another radio operator pointed me to QRP labs. Said that this was a really cheap alternative to utilizing WSPR without needing a PC or your HF rig, problem is, it’s just a transmitter.
I think they have a receiver too though if i’m not mistaken. I’ve also heard of the SoftRock TXRX Ensemble, but that setup is a bit pricier, you can get started with a single band with QRPlabs for just around $50 after you get the gps receiver and shipping. Pretty nifty for just fitting in the palm of your hand!
From what i’ve gathered, the kits aren’t too terrible to assemble, so I went ahead and snagged one, i’m sure it’ll be awhile before it gets shipped here from overseas. There are quite a few instructions and videos on how to build one, and hopefully i’ll learn something from it. The KX3 assembly was a little over my head, I was just following step by step not really knowing what in the heck I was putting together!
