It's kind of subtle, unfortunately

Wow... didn't even realize that was there. Couldn't see the trees for the forest. Thanks Scott.

During the big CW contest, using N1MM and the multitude of function keys, there were a few times where I would select a function key intended for N1MM but my Thetis screen was highlighted so pushing the function key would do "something" to Thetis. At one point, it displayed the frequency w...

Well? Just when you think you had everything grounded... Even though the Ameritron ARB-704 PTT box wasn't being used with the amp and/or the amp not even used, the box was not grounded. After grounding that box, no effects of frequency changes. Guess it was finding it's way back throu the RCA jack t...

I have a problem when using WSJT-X that when I transmit, say I am between 500-1000 Hz on 10 m (28.074 MHz) and the software will tell the radio to transmit at 28.073 like it should but when it unkeys, it stays at 28.073. This happens on any band. I have a beam antenna up 8m above the shack and trans...

You are not really "remoting in" since you are on the same LAN as the ANAN hardware. But, yes, having an operating position away from the hardware, and I do that as well, does require some changes to operating style. Very true on "remoting in." I've gotten so used to the equipme...

Dave,

Yes and that's isn't my question. If I hear it when I press TUN, why can't I hear it when I'm in CW mode?

I've been pondering and digging, not finding any references and this is leading to side tone with CW. I remote into my local radio in the shack (remote is in the house and the shack is about 50 foot away from the house). When I click TUN, I hear a tone on the speakers. I know there has been discussi...

Well, in the immediate answer, I have a fix. Not sure if it is the correct fix but it works now. If I need an education on how Muzychenko's Virtual Audio Cable works, I'm all ears. I don't have a diagram but I have my ANAN out in my shack, connected to a computer and network about 45 feet away from ...

If you could previously hear RX audio through your headphones but can't any longer, you've changed something in the VAC settings and need to revisit your VAC Settings page. I have a folder of screenshots of every Settings page so if I ever fat-finger anything I can get back to the configuration tha...

Thanks Gary and that is what it was for reasons unknown. I didn't take a screenshot but it was quite out of sync. It's reading zeroes now and doing fine and the overflow box disappeared. Still don't have any sound to the headset from the computer. One thing I didn't add before was this is from the r...

Just below VAC1, is this little red square, green square. I have Virtual Audio Cable installed and using Line 1 for transmit receive and Thetis is displaying reception on the spectrum. image (24)~2.png I'm using MRP40 and it will transmit CW using it, also lined up with using Line 1 for audio but li...

Scott,

I believe it does.

If and when it occurs again, I'll get a snap of the Thetis spectrum.

Sometimes when shifting modes and/or bands, I'm seeing this noise. There is no rhyme or reason to it and seems to affect 30 meters the worst. I have not seen it above 15 meters. When noted, I simply turn Thetis off and then back on, problem goes away. Is this a corrupt database and need to rebuild o...

Thank you, Scott.

One other question.

In transmit, where is the setting for TX or PTT delay? I saw for CW the transmit delay was set to 300 ms.

In some reading, I'm finding recommendations for anywhere from 15 to 30 ms for TX Delay.

Is there a separate tab for the actual PTT delay time?

Received the Ameritron 704 today.

Whew!

Works like a charm. I am a happy ham now. Can't wait to fire up some serious power now with the key. Huge lesson learned and avoided a major disaster.

To all, Thanks for the inputs.

Thanks for the check.

I'll be getting the interface buffer in a day or two. Hopefully this'll be the ticket.

John

Thanks, Scott.

I should have it in a day or two.

I'm still concerned about the 11 ohms. For any continuity measurement, that, to me would be out of spec. I'd expect less than .5, no more than 1 ohm.

John

I'm learning more and more about this amp. Yes, it was modified and this is what I have. It is a Russian GU-34 amplifier built into a Heath SB-230 case using the same power transformer and RF deck that the SB-230 used. It has GI-46 tube installed. If I need to get the interface relay for this, I wil...

Absolutely. With the holidays approaching, gonna be tricky but I'll get under the hood, time permitting and answer here.

John

First, to answer your tests in regards to the relay on the amp and two the PTT on the radio. No, the radio is not damaged. in receive, the PTT out reads infinity and when keyed, reads 11 ohms. Not sure what the parameter is for this but it does not read zero.  The amp relay closes when shorted acros...

I recently acquired a Heathkit SB-230 and the previous owner used it with an Icom IC-7300. Worked wonderfully. Educate me where I'm possibly missing a step. I have Ant1 going to the input of the amp. Output to an SWR meter and then into a dummy load (until I can assure myself this is working). I hav...

I agree, Scott. One, it will let me better understand the process of the level calibration with this rig and two, it will ensure that the S meter is where it should be. I will have to probe the locals for a good, calibrated signal generator.

John

Didn't even get that far with the battery.

Guess I'll never understand Gremlins. Reset the database and levels were back to normal. S Meter doesn't show that S5 level noise any more.

Thanks for the tips and off to work on re-building this database.

John

I will attempt the database from a fresh perspective first. Beyond that, I will have to acquire a well regulated, calibrated signal generator if the default calibration standard replacement proves no change. The power supply is a switching supply from Samlex Model 1235. The signal is being seen from...

Thanks, Gary. I'll take a closer look at the procedures and go from there, then report back the outcome.

I noted the other day, when I had my rig (7000DLE MKII) connected to a dummy load, tuned to the 40m band, I had an S5 level of noise. I went to all of the other bands and the S level was 0. Is there something that I should've done on receipt of this rig to ensure all bands were receiving properly an...

I do not get the yellow flashes. That could be indicative of a slow switch back to receive. Scott, I agree. I am wondering if the relay isn't releasing fast enough. What did you change to get this far? You talked about the under and overflows so I started making adjustments to the latency to make t...

Success! I have made two videos. One using the FT-450D and the other one using the 7000. In the 450, note the left gauge for audio input stays green the whole time during transmit and receive. https://youtu.be/MzyEaQLH9JE Using the 7000, note the flicker of yellow between transmit/receive on the lef...
