Hi gang, I got my new vise and put it together wrong the first time. But now it works just great. I can now build some more SMC boards and it will be a lot...
I just put up a wire vertical from W1FB's book and I can't believe how well it works. It's cut for 40M but it's closer to an all band antenna.My MFJ tuner...
... Hello Frank and everybody, I'm always interested in small wire antennas, so please, could you describe your antenna? It seems that works very well. Thank...
Hello, Here is the configuration to build the wire antenna I posted. The Vertical itself is a 14 gauge insulated wire up into a tree at about 40 feet at the...
I put up a couple of pix in an album. The first is a 40M transciever built in a plastic electrical 4"X4" box with about 500mw output. The meter is junked out...
... Hello Frank and everybody, Thank you very much for the explanation of your antenna. I'll try that configuration when I have the opportunity. Here, in EA8,...
Well,it's been quiet here for a while so I thought I'd ask if anyone is homebrewing anything. I'm personally working on a 2 watt xmtr for 40 M. Figured to...
I finished the 2 watt xmtr and it works fine. I used a 2N3053 for the PA and the keying is crystal clear. There are three xtals in the set and a front switch...
Hi All. I'm just getting back into QRP activities, including building. I had sold my old Heathkit HW 8 some time ago and have just ordered an Oak Hills 100 A...
Dave, The url for emtech is emtech.steadynet.com. They're very much in business and I build the NW-30 which I was pleased with. Terry KS9Y ... From:...
Hi Terry, Thanks for the note. Yes, that's the url I used. They never answered my email and when I called the phone number listed (twice) on this web page,...
Hi David, changing frequency is just a change in the number of turns on the various toroid forms and a crystal or oscillator that tunes 30 meters. It should...
hi David, Changing from 80 meters to 30 meters is a large change. Changing the frequency of various tuned circuits by just chopping the coils will change...
You can buy a 30 rig from Small Wonder Labs for $55.00 In my opinion, that would be the way to go. 73 ========================================= Radio Amateurs...
This Sunday evening, the Flying Pigs Amateur Radio Club International will be holding its monthly Run For The Bacon. This is a friendly, two hour QRP CW...
Anyone know if Emtech maker of the Norcal QRP antenna tuner sill in business? They list on there web site a Polycon dual section capacitor 266pf it dosen't say...
Joe , I had a similar experience trying to reach them a month or so ago and posted such. Someone posted back that Emtech was very much in business, but with...
I bought an assembled and used NW 80 and have had one contact with it and didn't notice, but tonight realized that both sidbands are un-suppressed on receive....
Hi David, You should only hear the one sideband, not both. Something is wrong with the rig. Check the xtals in the filter for solder problems. Also, the...
Hi Chris, Thanks for the response. I contacted the previous owner and he said that's normal when the bandwidth is wide and to narrow the BW and the "extra"...
... Yes, that cured it. I have been listening with the bandwidth control pretty wide open. When I turn it to about the mid-point, one sideband (the lower)...
I'm really enjoying the Emtech 80 meter xvcr. I'm impressed with it's sensitivity and I'm measuring about 3 watts out. Break-in is very smooth. This is...
Over recent years I have acquired several of Dave's SW series rigs and had terrific fun with the two I've built. But, and here's a sad confession, I never seem...
A rotatable wafer switch could be used to control some relays would really be (I think) the best approach. You really only want one rig powered up at a time so...
