Hello all, This is a reminder that the 2005 Oregon QSO Party is this Saturday, 12 hours only 14Z ma7 7 to 02Z on May8. All 36 counties will be active -- work them on both modes for a full multiplier
I had misgivings about colliding with three other parties but it was fun. I'll gladly trade a BERMA for a KLA OR, a Storey NV for a DES OR, or a DEL IN for a WHE OR. Now all we need is some software
The Icom's relay is rated at 60V and 0.5A. Using this to switch the Alpha's T/R line is about the same as no load. The current is < 2mA on key down. That's mouse nuts! Go for it, Clive. Dick Frey k4x
Sorry about the keying troubles with your amps, Dave. Clive's question was about switching his Alpha. I am very familiar with the control circuit in the Alphas. Their relay coils are never switched d
In addition to Googling Pluto II and JORN, try HFSWR. That is the proper current terminology. Our Canadian brethren are in on it too, but the primary domestic driver is Uncle Sam's own DHS. Dick Frey

Those eastern "alligators" who were S-8 here on the west coast and deaf to all the stations calling ...were probably using receive antennas with good F/B pointed elsewhere. When I operated from K8CFU
Rich, The way it's done professionally is with an active load. That's just a big transistor or two on a heatsink with an opamp to control the gate voltage or base current to keep the load current con
Dave, I got this thermostat as a sample 20 years ago when I worked for Ten-Tec. A Google search came up with this reference: http://www.ti.com/mc/docs/precprod/docs/6786.htm The 6786-2 is about as bi
Three weeks to go until the Oregon QSO Party. Go for the cheese! It's a 12 hour event on May 8th. All counties will be active. See www.codxc.org for rules, maps, and other help. Same weekend as the n
All computers run on DC sooner or later. It's stupid to supply 12V DC to an inverter to operate a laptop's 117V AC supply to provide some DC back to the laptop. The laptop has internal regulators tha
We have no experience with your unit but.... Our club ran a complete station - Omni6+ and SB200 amp from its smaller brother, the EU1000i. We also ran three 100W stations plus fans, computers, and de

Does anyone have experience using a TS50 with TR (or CT)? I am setting up for a state QSO party (see www.codxc.com) as a rover. TS-50, SG-239 autotuner, 12' whip, and a Dell laptop. I want to do inst
I am looking for a small rig to take on a low pressure DX-pedition. The country's power limit is 150W. The obvious answer is one of the smaller "mobile rigs' IC706, TS-50S, FT-100, etc. My question i
The purpose of my question was to determine which small 100W rig was best to take on a DXpedition where all rigs would be fairly close together but all limited to 100W. My thanks to all 25 who respon
30 responses received. No pattern. Astron, MFJ and Sanlex all equal. Everyone who has tried the small light 20/23A switches likes them for what they are - small and light. They are usually not noisy
