Hi Mike, What I'm going to propose you is going to sound a bit crude, but it might help. If you have a receiver you can tune it to the frequency where the 555 is operating and instead of using an RF
Very interesting. My understanding of the datasheet is that they are good for 50 mating/unmating cycles and temperature at the junction will rise by 30 degrees with a current of 18A (when within the
Thanks Jim, I found the connectors not reliable enough when they get old... but perhaps nobody was expecting radios lasting as long as some of ours, or maybe it was decided to keep the molex in order
mmm... digital noise from the frequency counter? Can you cut the DC suply to that module and tell us what happens? 73, Carlos VK1EA across all bands and it is in the background. It measures about 1kh
Hi Lyman, I don't know why do you have that funny reading on 10 MHz. I have never studied the heterodyne VFO topology or which corrections is the frequency counter making depending on the selected ba
Hi Lyman, Happy to hear that. As others mentioned, you might have some noise getting into the DC bus that is not being properly filtered and finds its way to the audio amplification chain. If you hav
Hi Tom, It is not a difficult job, it is mostly about dismantling, cleaning, lubricating, and assembling back. Parts are small, some are fragile, and go in a certain order. The day I cannot longer do
Hi Steve, There is a cable inside the radio prepared for that, I don't think you have to make any wiring (other than passing the cable through a tiny gap in a PCB). Do you want me to take a photo? 73
Hi, Some TT radios have an RCA connector marked as "RX Antenna", together with a "RX / TRX" switch. I cannot make sense of the user manual (perhaps because I'm not a native speaker) and by looking at
Thanks a lot Carl, Anyone knows what is the RF level there when transmitting? Is it safe for an active RX antenna? Thanks, Carlos VK1EA _______________________________________________ TenTec mailing

Hi Bob, Please let us know if you find a source. I have a Corsair II with the wrong knobs, they are aftermarket ones from Mouser. 73, Carlos VK1EA that _______________________________________________
Gary, can you terminate the power amplifier module with a 50R load and measure RF/DC power there? Just thinking about some bad LPF. Carlos VK1EA _______________________________________________ TenTec
Hi Perry, I cut the main body (the four flat arms) with a dremel tool, leaving a thin ring only. Then I (very) carefully "peeled off" that ring. If you do it hastily you'll distort the aluminium part
Hi Jim, Does the current consumption go up as you turn the power knob to the right? I'm thinking of an issue in the LPF filter as Gary mentions. 73, Carlos VK1EA CW & no _____________________________
Well, it seems that RF is being generated but it finds no way to leave the radio. I would check the LPF board's relays as Gary pointed out. 73, Carlos VK1EA reaches about the 40% position (1100 or 12
They have to be different, as lots of old parts have become obsolete. 73, Carlos VK1EA have bought the Omni7 + that was on display at the end of the day. but basically its the same as the old Omni7.
Hi Mike, Thanks for posting this. I don't know how does the radio compare against a Ten-Tec... but the music that goes with the video (which, at the end of the day, represents their company) is annoy
Hi all, I just bought an Eagle 599AT with NB from a local ham in Canberra. This radio is very rare in VK, and even more finding somebody in your town selling one (Canberra is the capital city of Aust
Solved ! Following the advice given by a list member, I removed all connectors, dusted them off with compressed air (gently), including the potentiometers, and the problem went away. It was deffinite
