Re: Tariffs and zBitx Shipments #zbitx

 

If Trump is serious he will enforce the Rules of Origin that will tariff goods shipped to an entity in the US that does not perform "substantial transformation" of the product. Otherwise everyone could just rent an office in Delaware for a paper transshipment company and claim their products are made in the USA.
?
In the past suppliers like DigiKey broke out tariff cost as a line item in the invoice so customers could see the actual costs. Others may choose to do that rather than raise prices and take the blame for the cost increase. This seems to be the route that Europeans take with their VAT.
?
If a tariff applies to a product that we in the US buy, we get hit with a double whammy. Not only the tariff itself, but the carrier, like DHL, charges a fee for handling the paperwork. I experienced that when buying a telescope from Germany years ago that was over the De Minimis.

Re: Mike Black W9MDB SK

 

Thanks Ken, N2VIP for keeping an eye on what's going on.
Unfortunately, many people ignore all respect and understanding regarding the deceased amateur.
Unfortunately, this policy comes from the street and spares no one.

I thought about calling the questioner's attention, but who am I to instruct him in order.
A 74-year-old old man who knows how much time he has left, because our fate is not only influenced by our actions.

For me, Mike, W9MDB helped a lot at the end of December last year, when I asked in another forum how to eliminate the error message 'Error in SoundInput'.
Since then, with his help, I can use the jtdx program on sbitx without restarting.
So my thanks go to Mike, which I did back then in response.

Re: CW on zbitx

I recently powered up my zbit.? I had an official Pi keyboard and mouse connected through the supplied OTG adapter before applying power.? The zbit power and drive were both set to zero as I had no antenna connected.? The radio seemed to key OK from the keyboard, according to the sidetone I was hearing.

A couple of comments and questions.

Why is it necessary to use an HDMI monitor when updating the software?

I couldn't see the mouse pointer with the above-mentioned connection.

Re: CW on zbitx

 

I assume you can use extern's with these separate files.?? I suggest to use one.? As an example call the variable
cw_tx_now.? It will need to be defined as extern in one of the files and just declared in the other.

Re: CW on zbitx

Eric, thank you very much for performing that test. I read through your code and I think that you are calling modem poll on every tick.

That would certainly suggest that your newfound success indicated it needed to be called more frequently.

I have a suspicion that it will similarly work pretty well even if you call it every fifth tick would you be willing to try that? That would be four times faster than it is currently being called and I think that would allow people to get to 30 words per minute, give or take. I’m just curious because I want to see just where the effective “ Shannon limit “ is?
reached for human perception. ??

Again, thank you very much for trying that test. I don’t have the radio so I can’t make the test.

?I think somebody else explained it very well. That Ashhar was now reading the paddles extremely rapidly, but not acting on it rapidly. You apparently fixed the latter, ?with the fix we thought would work

zBitx SSB contact

 

I had a 20M SSB contact with NC from Chicago (640 miles)- got a 1/1 signal report but was able to exchange call signs and name. I think I have a slight amount of desense so probably need to work on that a bit but it definitely worked on SSB. I've had a few FT8 contact also.
