Last fall, on ARRL's emergency power day, I ran my Argo V at 20 W (also CW) with a 12 AH battery. It lasted for about 5-6 hours of operating. Maybe if I had run it at 5 W it would have lasted all day
No, the VOX in my O2 works fine with AUX input. You have to set the AUX input for very high sensitivity -- mine is set for 75, but the exact setting will depend on the computer output level. Rather t
I can't find a control for that either. It looks to be a fixed-level output, since the AF output control does not affect it. So, I use the computer's mic gain setting as the RX audio level control. T
I beg to differ, at least to the extent that I would like the audio response to be user-selectable. Reducing the bass roll-off would adversely affect the radio's ability to get through DX pile-ups, a
I've tried my old Autek QF-1 audio filter, which can narrow down to 30 Hz, but frankly I find the O2's DSP noise reduction to be far more useful in pulling weak signals out of the noise. A clear case
I don't have the white dot, but I also have my call stored in SEND1. Last night in the DX contest I did notice that I was losing the first few characters. This was the first time that had happened, a
An interesting thing happened to me yesterday. I wanted to record a CQ TEST in SEND 3, but the O2 tried to insert delays when I sent with my paddle. That didn't happen during normal operation, just w
Hi, I have posted previously about the start-up problem my O2 has had. As long as I left it on, it worked fine. If I turned it off and left it off for several hours or more, then turned it on again,
There is no separate connection for a paddle and a straight key. You can use a straight key by plugging it into the paddle jack and turning the keyer off. To get a "tune" signal with a paddle connect
Hi, I'm sorry to have to report another bug. The O2 simply stops transmitting and receiving, while the TFT display and meter light remain lit. The display is frozen. This happens totally at random --
Hi all, I have a question about the internal keyer in the O2. Is it just me, or does the keyer in your O2 seem to "fight" you after you've been sending for a little while? I know I'm not describing t
Further to my posting of last week about "Another O2 bug," here's what happened subsequently. Wednesday morning, the O2 crashed along the lines of my previous report. However, when I tried to bring i
Please forgive this dumb question, but now that I've downloaded the new firmware, what do I do now? I plugged the serial port into both computer and O2, installed the software into the computer, hit
Carl and others, Thanks! It turned out that the software was trying to use COM2 while the serial port was COM1. The new firmware is now loaded into the O2, and I've done the recommended master reset.
2.028 fixes several problems, at least so far. I'm still waiting to see if my no tx- no rx problem recurs. However, one thing it does not fix is the internal keyer. That still tries to insert delays
