I'm sure it varies a lot from QTH to QTH, but here, over mostly volcanic ash and sand, I could see significant difference between 800 foot and 1100 foot. I never got around to trying longer than 1100

WSPR and WSPRnet.org are fantastic tools. Used properly, they make the Reverse Beacon network look like a kids toy. I have used the WSPR system to watch propagation and evaluate both TX and RX antenn

Milt, Are you familiar with WSPR, it's setup, operation, and it's relationship to WSPRnet? If not, then details won't help much. In a nutshell, it involves collecting data. Thousands, perhaps even te

Jim, Participation varies. At the moment there are more active WSPR stations on 630 meters than on 160! But as we roll into winter there will more show up. It is important to remember that this is a

Normally, I run 5 or 10 watts TX output on 160 meters depending on the specifics of the particular run. On 30 meters it's kinda dumb to run more than 5 watts out unless your antenna is a light bulb i

First thing, 160 meter is NOT the Topband and hasn't been for a number of years. 2200m is the Topband, with 630m in second place, and 160m a distant third. There are two areas of interest in the MF/L

RE: 2N5109 replacement With my supply of 2N5109's getting low, I looked long and hard at suitable replacement parts. There just isn't anything made in a leaded package that's worth while. I did find

Beware of ebay 5109's. Most, if not all, from Chinese vendors are counterfeit. They usually don't work well, if at all, in place of a real 5109. Larry - W7IUV _________________ Searchable Archives: h

FYI, since the genuine 2N5109 is so difficult to source (and the 2N3866), you might want to look at using a DCP68. This is a surface mount device that will electrically replace the 2N5109 in the W7IU

My RX is monitoring 160m FST4-60 and will be at least overnight. It is reporting to PSKreporter which does a good job of reporting activity if people bother to enable that function in their software

Yes. Quite a few of us are active on 630m. Activity is world wide although not so much during the summer months. There are always beacons to be heard, mostly WSPR and FST4W-120. QSO's via FST4-60 usu
