The audio spectrum looked real clean and flat from about 100 Hz to just under 3 kHz. The recordings through my SDR, with the drive set reasonably, sound pretty decent with my gravelly old voice. I didn't actually measure the intermods from the two-tone testing, but I had to drive it pretty hard to see them. Adjusted properly, it seems to have really good audio. There is enough drive using an EV-727 microphone to make the output look like just a pure carrier on the o'scope. The modulation looked good when properly adjusted. I also connected my O'scope to the RF output. I did some two-tone testing and some voice testing/recording through my SDR. Total RF to the dummy load was about 40 watts. Total input power to the rig was about 90 watts from the power supply. In the tune/CW (LOCK) mode I was seeing about 0.9 RF amps into the dummy load at 7200 kHz. With that, I connected it to an Astron RS-7A power supply, which gives me about 13.8 VDC up to about 7 amps. That let me test the receiver, and was enough to let me check the basic transmitter functions into a 100 Watt/2GHz/50 Ohm dummy load. But, it is only good for a maximum of 1 Ampere. I initially fired this "new" rig up using one of my old lab supplies on which I can set the maximum current draw from about 10 mA to 1 A, and I can set the voltage from 0-50 VDC.

I don't have a companion 200 watt TT power supply to run this series of rigs - my biggest actual TT power supplies are Model 210s for my 505 and 509. I'm contemplating how I'm going to handle this issue as I write this. I just need to get a second set built.Īnyway, I'm just one happy dude this afternoon.Ĭlick to expand.Thanks for the heads up. My N3ZI DDS-2 will get moved from the Argonaut 505 to the 540, and I'll order a new DDS. It will replace my little Argonaut 505, which will take on new duties. Brief checks of the audio and ALC, with the transmitter connected to a good 50 Ohm non-reactive load looked pretty good on an O'scope. I'm taking a break right now, but I hope to have it on the air tonight after I do a thorough check of the transmitter. It sure lights up a 75 watt incandescent light bulb on CW, and I only have a power supply that provides about 12 amps at 12.6 volts, instead of a 13.8 volt/18 ampere supply. Best of all, it has all the factory upgrades/accessories, like the second CW filter, all the 10 meter crystals, noise blanker, etc. I've got black woodstove high temperature paint to touch up the heatsink. I already found "faux black leather" to re-cover the top cover. Other than the the vinyl covering on the top cover, and some paint missing on the final amplifier heat sink, the thing is pristine inside and out. I guess everyone else was scared of it coming from a dumpster. I was willing to bid up to $90 more than I got it for. He said he didn't have a power supply or microphone to check the transmitter, but the receiver seemed to work. The pictures made it look kind of horrible. The eBay seller said he retrieved it from a dumpster.

I've been looking for a good restorable Ten Tec Triton IV - 540 or 544 for quite some time.
