The Rigol DSA705 is a very nice spectrum analyzer.  I did a review of this for QST (July 2017).  It is $700 and covers up to 500MHz.  While it doesn't have a tracking generator, I show how to use a cheap noise source to look at filters in the review.

OP said he wanted to run WiFi experiments.  500 MHz isn't going to cut it.

The 811H is rated at only 1900 volts plate.

The PS is 1800V MAX before the caps are likely to go bang and running them at the edge like that is asinine engineering to start with.

No 811A manufacturer rated them there without documented proof, hearsay dont count.


Guess what? The caps do not GO BANG! If they did even a little the over 150 reviewers would report that issue on ehan reviews. However, I would never design an amp that uses caps at full rated voltage. In fact, I replace my AL-811 caps with 500 volt.

Here we are a year later and I just worked N4T/45 on 7.007. Claimed to be POTUS SES

Was it a joke ??

There are no  "perfect spectrum analyzers"!
So what is the budget? With this eqpt, there is a big difference between what you can afford and what you want.

actually I am more interested in clean signal generators rather than spectrum analyzers.

+1 on the Rigol.  They're present at Dayton every year, and offer it with the tracking generator.  Very nice brand, at an affordable price point.  Will probably pick one up this year.

Recently I have been trying to get the logging program "Win-Eqf version 3" to printer Qsl Labels on my Brother QL-700 Label Printer. The QL-700 printer uses drum feed labels that are 1.1 wide x 3.5 inches in length. For those that use that program, their is no setting for a label printer in a file called DDOCML.INI. That file has mostly sheet feed printer labels from Avery, etc. Their is a CUSTOM setting, which a user can set to the printer of his/her choice in that file. There is also a settings file for a QL-700 Printer that is found in the WINEQF2 folder, which I have tried to get to work. I have copied and pasted the settings in that file to the DDOCML.INI file's CUSTOM setting. Upon running WIN-EQF, and selecting to Print A Label, the preview window opens and shows the printed text in PORTRAIT mode, not LANDSCAPE mode. I believe that may be the problem. I have tried setting the QL-700 Printer Preferences to LANDSCAPE mode. Upon attempting to print, the printed label is in PORTRAIT mode. So, I am kinda stuck. I am using Windows 10.

I have heard all about the demise of WIN-EQF, and read all of the literature, etc. I still like and want to use that
program. So, there is no need to criticize me for using WIN-EQF.

Anyone have any suggestions. At one time their was a WIN-EQF group somewhere on the internet. That appears to have disappeared. I have seen the WIN-EQF Facebook page. It doesn't help much.

The maps scale is a little misleading.
If you look at it they only headed south for a little over an hour then turned around.  I think they are probably doing safety drills and testing the helicopters being launched and landed.  Just a guess on my part but I think a two hour set of test in open sea would be normal before taking on a task this large.


Could be, however yesterday's release said the only remaining hold-up was clearance to sail from the Navy.
