Thanks Mark! And I will advise either way.

Scott: Copy that!

Scott,

Fair statement.

Tell me, could the FPGA (the array is on the Orion board, correct?) be at fault?

Why wouldn't my Kenwood not exhibit this issue, using the same antenna?

Juha

Tried again this morning as the temperature in the shack is much lower and until now, lower temp has been the "saving grace." After about 30 minutes of monitoring, both RX1 and RX2 exhibited a very low noise floor. So, this appears to be getting progressively worse. How many separate board...

Tried another PC (laptop) and the same exact issue could be observed several minutes into monitoring, a carbon copy of the ebb-and-flow, on both RX1 and RX2. Same antenna, same band. At one point, I thought that perhaps I should include Thetis and The OpenHPSDR (in Roaming) sub-folder in exclusions ...

No joy. :( Rolled back to Protocol 1 and both RX1 and RX2 exhibit the same abrupt drop of noise floor after about 5 minutes. Floor sinks and bounces back to "normal" over a period of 1-2 minutes and this keeps happening once it starts. For the first 5 minutes, all looked good but I got my ...

Chris,

I am glad you haven't dozed off at the litany of questions and exchanges on this !

No, I haven't tried any other Protocol versions, but as Scott is suggesting, it may be time to try Protocol 1 for a look-see and it that remedies this anomaly I am fine with that !

Juha

I read you Scott!

One more "foolish" question. Will the latest Thetis version (2.9.0.8 - Pre-release) care whether I run P1 or P2? I assume that doesn't matter.

Thanks. Will do the experiment.

Scott, I have AC, but I don't run it always upstairs. By the way, Phil, VK6PH wrote to me yesterday saying "It gets to over 100F in my shack and I have remote access via the Internet so its not a temperature issue." It just hit me, you specified in a Firmware related post ( Jan 16, 2023 UP...

Scott, If 82F ambient is too high constitutes a serious flaw in the design and if this sort of temperature is "too high," then I think Apache-Labs would be encouraged to specify proper operating temperature. I live in Texas, so 82F is nothing untoward whatsoever. It is almost "cool&qu...

Mark, I sure value your kind suggestion and I may take you up on it :) ! My email is good on qrz.com. As for the mains voltage, it is in the range of 121.2V-122.0V, according my Fluke 107 meter (as of 9AM today, Sunday). Will check what the swing is on a weekday too. And, yes, I am no fan of PowerPo...

Shouldn't the DC power supply (Astron) be able to deal with minor swings in the mains voltage? And, no, I haven't been monitoring the mains, but did at some point think that perhaps my DC supply wasn't up to the task. Shouldn't I see a very low DC voltage displayed at bottom of the Thetis GUI though...

Tried it yesterday (monitoring for roughly 30 minutes) using the same antenna. After about 10 minutes, the noise floor went from around -119 down to -132 (occurred 3 times) before "stabilizing" and going back to -119. Decided to do it again this morning. After 30 minutes, no changes in noi...

Gary, I used the same antenna for both receivers, sharing ("common) the ADC. I went by what you had suggested.

Radio is ANAN 7000 DLE MKII (black front) that I've had for almost 2 years. It had been working flawlessly for about 1.5 years and it started acting up only a few months ago.

Juha

UPDATE: Tested again with the same antenna feeding both receivers (at least one less variable out of the equation) and the noise-floor went way down and then came up again to "normal" and this pattern continued for a few minutes, eventually, ending in both receivers exhibiting very low noi...

I will make another test tomorrow with the antenna connected to RX1 feeding both receivers and still another test with an antenna connected to RX2 feeding both receivers. Gary - NC3Z - advised me on this, using the ADCs. That way, we can take out the difference that having 2 different antennas conne...

Mark, I know what you are saying, but regardless of the scaling (it is a tad different, I noticed), the noise floor sinks very low, AND, the floor goes up and down so even with slightly different scaling (I will make them the same), it is obvious that something isn't right. Thanks! Juha UPDATE: Matc...

Mark, RX1 had an End-Fed-Half-Wave connected and RX2 is using an inverted V dipole at 33'. I will do the "swap" and post tomorrow. When it comes to signal strength, depending on where the station is, there can be a difference of 2-3 S units when I bounce between the 2 antennas. 73, Juha UP...

Gary,

No, the box is not checked.

Thetis version you can see at bottom of my post.

Again, I wish I could have attached a brief video clip but can't. The noise-floor ebbs and flows ion RX1 whereas it stays "steady" on RX2.

Scott asked me the same question many weeks ago.

Juha

"Last gasp" effort to understand why this is happening. To me, it would seem that there is something wrong with RX1. As I had reported quite extensively many weeks ago, RX1 exhibits a strange anomaly - noise floor dropping and then bouncing back several times in a row (regardless of band o...

Well, it is just a hobby, nothing earth-shattering and I guess I am better off going back to being an appliance operator and sell the ANAN. It was fun while it lasted

73,
Juha

I backed up the OpenHPSDR Program Folder and the OpenHPSDR Roaming Folder before deleting those 2 folders (Thetis still showed up in Apps, so I also uninstalled Thetis there), wanting to see if starting from scratch would make a difference. I won't go into the issues I had been observing, including ...

Scott, Router is plugged into the switch. Again, the hardware set-up is exactly the same as it was a few weeks ago. When I used the Bootloader I assigned ("WRITE IP") the IP address that I saw on the "H/W Select" form where it says "ANAN Address." From what you are writ...

Decided to go back to using the radio via an Ethernet switch rather than having radio talk directly with the PC (I used Bootloader to assign static IP addresses to radio and NIC in the PC). 1. Imported the Database that I had been using successfully (radio talking to PC via the Ethernet switch). 2. ...

For some reason, I had assigned the static IP address for the NIC incorrectly while thinking that I had found the problem

Got it fixed.......
Disregard

Not sure, but when using the Bootloader (to assign static IP to the radio, as I have done successfully previously), the utility finds the board in the ANAN and also displays the MAC address, but after I restart Thetis, nothing works and no MAC address is to be seen. See below.

I wait long enough for the hardware in the ANAN to be up and running before I click on the Thetis icon on my desktop.

ANAN is connected directly to the PC (static IP), no dedicated NIC.

Again, this has started happening only recently.

Juha

Lately, I have been seeing a pop-up (after clicking on the Thetis icon on my desk-top) to the effect that the radio isn't (hardware) connected or powered on, but it is. This is something rather new and I can get it all working after I restart my PC (powering down/power cycling the radio won't help)....

Thanks Steve!

How do you make sure that a meter floats (perhaps that isn't the correct term as I want the meter to stick to the GUI) on top of the main GUI? When I switch from GUI to surf the net, the meter shows up but not the GUI. How do I avoid the meter showing up (with no Thetis GUI visible) when I am in &qu...
