Frequency Tuning Delay

Al Matthews

I have a 6600m and a Maestro v2. I am using 2.4.9. On the 6600m there is a very noticeable delay between turning the tuning knob, and the frequency actually changing. The 6600m is wired directly to the router. The Maestro does not exhibit and noticeable delay, and it is running on the wifi network. The delay on the 6600m is severe enough that it makes it difficult to tune a station in. Does anyone have an idea why this behavior is happening, and what I can do about it?

Just another datapoint: I have a 6600M and experience zero delays tuning on either VFO knob. Running 2.4.9.

I have seen something similar with a Maestro A and a 6500 with 2.4.9. My hypothesis is that it's the router doing some kind of extra buffering or bloat. Next time I will compare with a direct wire btw Maestro and 6500. Bet that will eliminate the problem. If so, try swapping in a different router or (shudder) fiddling with router parameters.

One other thought: You mentioned that the tuning knob on the M front panel showed a serious delay. This interface is directly connected internally to the 6600 radio. However, they are on a common network connected via the internet jack on the back of the radio. What happens if you disconnect all internet connections from the 6600M? Does the tuning behaviour change? My thought is if there is a large flood of traffic on the network, it could definitely interfere with communication between the front panel and the radio. It’s easy to verify, and just a thought.

Actually, he said a Ver 2 Maestro was where he found the slow response - but I also wonder how the response is on the M front panel.

Al Matthews

That’s very interesting Duane. My WiFi connected Maestro V2. Has no lag but the 6600m has significant lag. I am using the same router that you are.

Al Matthews

The serious lag on the 6600m is still there without the Ethernet connection.

Since the only way you can run an M with no Ethernet is with the internal UI, it sounds like it’s internal to the radio, so a matter for Flex to solve. Edit: Have you tried a factory reset of the radio?

Sorry - missed Al's response above when I responded.  Carry on!

No Ted, I haven’t tried a factory reset of the 6600m yet

I have made some simple tests to discover the scope of the problem. When I turn the main tuning dial on the 6600m, there is an approximate 1.5 second delay before the frequency actually changes. This makes is extremely difficult to tune in any signal. If, for example, I spun the dial quickly for a change of 50khz or so, it might take 2 or 3 seconds to catch up. I tried without the internet connection, and no change in the behavior. The Maestro v2 on wifi, has no problem at all. SmartSDR also works perfectly. The issue only exists with the 6600m. Since there seem to be a number of us with this issue, and it makes the 6600m very difficult to use, I will file a report with support and ask for help.

Hmmm. It’s a puzzler Duane. My issue exists from boot up. The maestro and Pc work well without problem, and they are both on WiFi. It’s only the 6600m

Al Matthews

Thanks for the info Harold. It doesn’t seem to be universal.

I notice delays when on WiFi.  When hardwired there are no delays both on SSDR Windows and on Maestro.

Here is an interesting development. The issue has resolved itself with no changes to the operating state, other than turning the rig on this afternoon. The rig has been turned on and off many times while this problem persisted, but today, it is gone completely. It has been having this issue for about a month.

Hi Vidas

For a data point, I use a Maestro A and B both remotely with zero delays on the VFO's.  It is surprsingly good actually.

When we see this, we need to look at all the pieces of the path between the Maestro and the radio.  Even though you mention your WiFi works normally, most user operations do not required less than 100ms response time.  Moving Web data isn't the same as move HF radio data.  

If I was in your shows, I would look at ensuring that your hardware drivers are up to date for your devices.  I've seen this some solutions as simple as this.  

For your slow Maestro issues, if you did a test with a LAN cable connected to your router and not use WiFi do you still see the same Maestro slowdowns?  The other thought is you can try lowering your MTU value in the Maestro to a value like 1400 and see if that helps.  It is in the network settings/advanced.

Actually, the problem has returned. Before the factory reset, I will try removing the power from the supply. Thanks Warren.

Al,
What is the current status?
Flex says that delays is a software problem but is is not clear whey only soem Maestros have problems and not all the time.

This issue is still assigned to our software team for resolution.  It is one of the higher priority items in their work queue.  At this time I do not have any ETA information.

Al Matthews

I sent you an email some time ago Tim. The issue is directly related to the hdmi port use. The problem never happens on my maestro. If I have and hdmi monitor plugged in to the 6600m, the tuning delay is close to 2 seconds. Operation is normal if I simply unplug the hdmi connection. Its a very nice ability to have, but it doesn't keep me off the air. I will look forward to a resolution. 
Thanks
Al
