You can select the portion of the screen to read. if there is readable text there it can help. If the video has good verbal instructions with video demonstrations they can be of some help for a blind

This is probably a military format and likely Russians are involved. There is a war going on thanks to the Russian psychopath. {^_^}

You do not need any vision at all to use a screen reader. You need some sighted help up front, maybe, but cursor position can be known pretty accurately with sound cues, especially for people with ver

It may be an internal powersupply that takes 13.8 VDC down to 5 VDC. In that case there is no help for it without significant surgery. {^_^}

I have a SICK SICK mind. You made a broad statement and my head wondered if the 24 caret Gold Plated CW Key was all that absurd. I experienced my typical blur of possibilities fly through my mind and

I am not sure why contesters at multi-op stations don't use rigs with the best TX signals they can get. With adequate antenna separation you can place more operators on the same band. It's a serious p

Start as clean as you can achieve then use PS if it is available. Both right. There is no single perfect correct way. Judiciously combine methods to make it better. (Wash hands, isolate from others as

I was with you until that last snipe. It appears the 7300 MAY have a problem. If it has spurious at -3db from full output that are only 60 dB down removed 20 kHz and 100 kHz from the carrier that can

Um, 51dB (the fractions are imaginary) is not all that good even at 1 kW. It's better than what you can buy today, for the most part. But. it's not very good when 60 dB to 70 dB is available and achie

There is an economics pressure here. Who is going to be the first company to give up being price competitive in a small commodity market and will that company survive the hit to its bottom line? A LOT

Mark, I flashed on one of the favorite 6-meter hacks I communicated with. The other ham worked at a military radio repair facility. They had huge bins of 6AC7 receiving pentodes in metal encased bulbs

On a hunch - run the radio on batteries. That this could be power supply noise modulating one of the stages or (horrors) the D/A converter's reference. (And I sort of wonder what the instrument's own

Looking at the Keysight picture you posted it's hard to tell the characteristics of the peaks that appear beside the (was it?) 28.4 MHz signal. (The screen notation of 390 kHz is confusing. That is th

Um, I am not sure I understand that picture. That is the analyzer's specification or something very custom you have put together? I'm answering both emails here. If that is the noise level you are ins

I suspect your specification is still beyond the state of the art. Is your transmitter that good? It sounds like the 7300 is cleaner than average close in but has some issues fairly far out. That is a

OK, please refresh my mind what you mean by "clean". It certainly appears to be sending something much closer to pure signal concentrated within its intended bandwidth than most other transmitters. I

I am not clear what you mean by "between the modulation". The full feedback process for improving modulation characteristics attempts to make the transmitted signal as close to a perfect rendition of

Military contracts fall into the code names and acronyms to the point whole conversations seem to exclusively use acronyms without normal nouns, verbs, and stuff. I'm glad I am out of that now. {o.o}

So I learned as I read messages. I was suspicious that some meta data had gotten stripped off in the editor he used. {^_^}
