Best AGC for digital modes?

Is there a consensus for the best AGC settings for digital modes? A recent presentation by the Contesting University recommended off if possible, or slow. Thanks for opinions.

Re: Which rear connectors to use for Navigator modem?

Thanks, Scott, I'll use pin 10. I haven't given up on virtual audio. But I have the Navigator hardware sitting here, and would like to run side-by-side comparisons. For VAC, I currently use Voicemeeter's A-B cables, set at 24 bits 48K sample rate and that works pretty well.

Which rear connectors to use for Navigator modem?

I'm going to try my Timewave Navigator modem with my 200-D, and plan to hook up through the rear DB-25. It looks like pin 1 is PTT, pin 21 or 25 for ground, pin 10 or 22 for line out, and pin 12 for line in. Is this correct? Also, is it only RX1 that is routed to the rear? Anyone using one of these ...

Tried Thetis again, now VAC is broken.

I have, from time to time, tried Thetis on my 200D and always with the same results. It doesn't work with VAC2. Up to now, I've been able to roll back to Protocol 1 with the bootloader and go back to 3.4.9. This time, however, PowerSDR will not work with VAC2, giving a port error (see attachment). I...

Re: First attempt at Thetis

Re: First attempt at Thetis

I've been trying different things all day, and it seems that, on Thetis, VAC 1 and 2 cannot be used simultaneously. VAC 1 will transmit only if VAC 2 is turned off, or set to ASIO (but then it cannot be piped to another program). I would like to hear from anyone who has VACs 1 and 2 working together...

Re: First attempt at Thetis

I have just found that, if VAC2 is turned off, the microphone will transmit, even if RX2 is on. If VAC2 is then enabled, with no other changes, the microphone will not transmit. Any ideas on how that could be?

I've been using OpenHPSDR 3.4.9 on my 200D, through a dumb network switch and a windows 10 i7 desktop, and decided to try Thetis. I used the bootloader and Orion_NP_v1.2_restored_4-17.rbf, which I had to rename metis.rbf. Bootloader reported successful programming of the protocol 2 firmware. I then ...

Re: Problem with multiple antennas

I connected RX2 directly to the splitter, bypassing the switch. When tuned to WWV at 5.00 MHz, the signal on RX2 ranges between -68 and -72 dBm if RX1 is on the other antenna, and -91 to -97 when they share the antenna. So yes, the approximately 25 dBm attenuation is still there when the switch is b...

Problem with multiple antennas

I have two receiving only antennas: a 300-foot Beverage and a nine-foot active vertical. They each plug into ANZAC splitters. Those run, for RX1, to PowerSDR antenna inputs 2 and 3, and for RX2, to an Alpha-Delta switch that controls whether RX2 receives from the Beverage or the vertical. I work a d...

Phil, thanks. I ordered a 2.4 GHz keyboard/mouse as recommended and will see if that helps the freezing. I've not had problems with either monitor (yet). I use only VAC for audio so don't worry about the line connections front or rear. Nice looking case for your 200D.

Hi Bob, As for distribution to multiple radios, since the 10MHz inputs on the Apache Labs radios are high impedance, you can generally get away with using T connectors.

After days of effort, I got ntp to work with the GPSDO. I still can't get PPS to work, but maybe it doesn't matter: the GPS shows delay of zero, offset under one, and jitter also under one, after running a few minutes. This is not something I would recommend to the faint-hearted, though. Buck ko0y
