Re: de minimis shipping to US from China is ending
This is essentially an embargo, because it will slow down a package
for months. It is a part of the trade war which is wreaking havoc.?

Re: de minimis shipping to US from China is ending
It seems to say that IF it¡¯s under $800 AND not shipped via International Post THEN it will be subject to a tariff¡¡ maybe I read it wrong?
It clearly states China.

Here is text from the US government:
?
¡°Today, President Donald J. Trump signed an Executive Order eliminating duty-free de minimis treatment for low-value imports from China¡¡±
¡±
- Following the Secretary of Commerce¡¯s notification that adequate systems are in place to collect tariff revenue, President Trump is ending duty-free de minimis treatment for covered goods from the People¡¯s Republic of China (PRC) and Hong Kong starting May 2, 2025 at 12:01 a.m. EDT.
- Imported goods sent through means other than the international postal network that are valued at or under $800 and that would otherwise qualify for the de minimisexemption will be subject to all applicable duties, which shall be paid in accordance with applicable entry and payment procedures.
- All relevant postal items containing goods that are sent through the international postal network that are valued at or under $800 and that would otherwise qualify for the de minimis exemption are subject to a duty rate of either 30% of their value or $25 per item (increasing to $50 per item after June 1, 2025). This is in lieu of any other duties, including those imposed by prior Orders.
- Carriers transporting these postal items must report shipment details to U.S. Customs and Border Protection (CBP), maintain an international carrier bond to ensure duty payment, and remit duties to CBP on a set schedule.
- CBP may require formal entry for any postal package instead of the specified duties.
- The Secretary of Commerce will submit a report within 90 days assessing the Order¡¯s impact and considering whether to extend these rules to packages from Macau.¡±

Re: Feature Request List?
I¡¯d like to see the QMX and Plus be able to remember the last mode each band was in as you step through the bands.?
eg, I¡¯m using 20 meter USB and step through the bands to say 40 meters. It would be nice if it remembered that I was using LSB the last time I was on 40 instead of having to change it from USB.
Definitely not a need¡just a luxury. Maybe it would extend the life of the encoder a bit.?

Re: Do I have a 9 or 12 volt qdx, qmx
It's safe to run either one on less than 9 volts. You want to try to limit the output power to 5 watts or less. If it's built for 9 volts, then the output power into a 50 ohm dummy load will be close to 5 watts when using a 9 volt supply.
?
This is the empirical answer.? For example, on my QMX, wound for 12 volts
?
Voltage |? 60m |? 40m |? 20m |? 17m |? 15m
9v???????? | 4.1W | 3.6W | 3.6W | 3.2W | 2.8W
12v?????? | 6.4W | 5.7W | 5.9W | 4.9W | 3.9W
?
?
I would wager that if the QMX is a 12 volt units that you will see somewhere around the 4W range for 9 volts.

Hans, customs might be more of a problem this year if you are bringing samples with you to FDIM.?? You will probably need proof of origin because "all electronics must be from China". unless proven otherwise.? Plan on paying tariff at point of entry.? Good luck, see you there.

Re: QDX + Digital Radio Mondiale
Umut:? Announcing your intention to operate a pirate radio station on a public forum is likely to (or, should) earn you the disdain of other licensed Amateurs, who obey the regulations,
and perhaps contact by, or even a visit from, the local PTT or whomever administers radio regulations in Turkey.??
I would suggest you re-think your plans.

Joerg, maybe it's really hard (impossible) to give a reliable answer.
- Who knows. I never saw and heard about such a situation. Maybe others also not?
- (The same)
- no other information than the last time
"but programmed STM32s are not available. Without these, a complete repair would probably be impossible." Yes, and if you already know this which answer do you want to have?
In my opinion the only way to confirm your first assumption is to remove the controller or lift the related pins and check the resistance. What should someone do from remote?

Many thanks for this Hans. Great work.

Is the internal microphone still disabled in this release. If so, when is it hoped to be activated.

Thanks?

Re: QMX battery suggestion
My 2 battery options for the QMX .. 3S or Anker 2000 pack with USB 12 vdc trigger
|
Re: QMX battery suggestion
That's a great price on a 2200 mAh 3S battery for a QMX kit.? How do you ship without paying much extra?
3S batteries are great, I have 1 ea 3200 mAh?+ 2700 mAh @ $25 ea from Amazon DIM 3" x 1.5" x 1" with eBay T x 2.1 mm x 5 mm barrel connector dongle?@ $8 ea.
Makes for a nice compact QMX kit.
Wanted to give a heads up - I haven't seen this battery in stock for a bit and I think it is a perfect match for the QMX.? I thought they were discontinued...
?
It's the Turnigy 9xR
?
3S LiPo cell, very small (approximately a stick of gum sized, a little larger), and it has a protection PCB built in to prevent over discharge or over current.
2.2AH of capacity, 3.3A max continuous current, 12.6v fully charged
?
Can't argue with the price either at under $10
?

Re: QDX + Digital Radio Mondiale
The QRP Labs QDX transceiver is designed specifically for single-tone frequency shift keying (FSK) digital modes, such as FT8, JS8Call, RTTY, and Olivia. It is not suitable for modes that require multiple simultaneous tones or phase shift keying (PSK), such as PSK31 or Winlink. Digital Radio Mondiale (DRM) employs complex modulation schemes involving multiple carriers and phase/amplitude modulation, which are beyond the capabilities of the QDX. Therefore, the QDX cannot be used to transmit DRM signals

QDX sends a single carrier... So other modes that are not single carrier are not possible.

QDX + Digital Radio Mondiale
Hello there , New Ham , New QDX user where the radio has been donated to me by TRAC friends in Istanbul. I reached Australia , Antarctica and Greenland with a 5 volt pc supply and an untuned cable antenna dropped from a window on a concrete wall.
Now , I want to transmit a few hours daily in - digital radio mondiale - mode and I will make a pirate radio. Can QDX help me ?

I have already received various offers from OMs who would replace the STM32. However, no one currently has a programmed STM32. Furthermore, I have not yet received any confirmation as to whether my assumptions regarding the possible defect of the STM32 are plausible. I find this particularly frustrating because I would prefer to understand and fix such errors myself.

An official ssb release, wow... Many thanks to you, Hans!
BTW.. I asked once but might have been missed.. Could the difference since prev version of the manual be highlighted? It would be way easier to spot new things among those 130+ pages..
