II Iam once again attemptiing to learn CW. They say its easy, just like learning a second language . . . although I failed in learning a second language many ttiimes too.
With our MMX and DMX-40, forget the attempts. Just have QSO’s, enjoy. Let your brain do the work via cognitive association! It is the only way to learn CW without the effort.
@@preppcomm Right after sending that commentt I watched another video where the MMX was demonstrated and the various ways to use it. Very interesting. The video was a year old, but at the end of it, you mentioned several upgrades that were coming in about a year, including the ability to do field upgrades. Is that possible yet? IIm looking at the MMX Zero that I would pair with my IC-705 and IC-7300
Unfortunately @@WH6FQE no. But soon, we hope. But to be clear, it is in a new product, not the current products. The limitation of requiring factory updates of software is built into the microprocessors in the current products. All new products in the future will use a different processor.
@@preppcomm@preppcomm ok, that's what I was thinking. Trying to decide if I should wait for the new product or not since at these prices, I would not be able to afford both versions.
Yes, you can absolutely start using it with zero Morse code experience. It will take a few months of use for your brain to Learn code without any effort on your part, based on the experience of other hams.
If you own an MMX you can add any of the available bands by ordering the band cards you want. If you have a DMX-40, you can purchase a DMX-40 to MMX upgrade, and select which bands you want included in your brand new MMX. Read the directions - the upgrade menu item is in the Products menu. You will need to send in your DMX-40, and after we check it to make sure it is fully operational, we ship your MMX. And, the DMX-40 is factory refurbished and sold at a reduced price.
It does take a little practice to center tune a signal, especially if it is weak. Of course a strong signal does not require as much care. Essentially, as you tune, stepping up or down the band, when you first acquire a signal, keep stepping a few more steps and stop. Pretty simple and you are pretty close to the center. To get a feel for how many steps, try a few signals by counting steps from one side to the other. That will give you a good idea of how many steps you need for a typical signal to center the tuning. Note: number of steps depends on step size. If you are going fast down or up the band (100 or 1000 Hz steps), and hit a signal, you have no idea where the edge is, so you should drop to 10 Hz steps, find the edge, and step back to the center. Unless it is really strong...
I hear you need a 10w dummy load attached if you wish to use another transceiver. Does it come with one? Also should you use ferrites to help keep things clean? Heard it bleeds out badly if any cable is crossed. Even if that’s not true what kind should I get to help, just in case?
A 5W dummy load is fine, and you can get one from Amazon for around $7. No, it does not come with one. We are fighting the rapid increase in parts cost (up to 40% in some cases), so little extras are out of the question at this time as we hold our price. I don’t think you need ferrites, but if you do, putting one on the keyboard cable is OK. We have internal filters, but if you run your keyboard wire next to the antenna wire, you are going to have trouble. It is not “bleeding out badly” but it is RF off of the antenna wire - depending on your load, you may have a lot, or a little. It’s just good practice to not run RF power and low power digital together due to capacitive coupling. I would not worry about this - it is information blown out of proportion by whoever. Follow good practice and you should be fine. Another good practice - don’t have the keyboard wire running all over the place. Bundle it up so it is neat and tidy, and the connection between keyboard and DMX-40 is short. Otherwise, you are just adding an antenna between the keyboard and the DMX-40, and if you have RF in your shack, it will pick it up, and maybe even overload our built-in RF filters. SO, the word is, follow good engineering practice, and you should not have any problems at all. We offer these tips because many hams have no idea with good engineering practice is. We are not offering this information because there is something wrong with the DMX-40.
We do have exactly what you are looking for, introduced on March 12, 13 at the QSO Today Virtual Ham Expo. It is the MMX Multi-Band Morse Code Transceiver. It has 3 slots for band plug-ins. You can order one, two, or 3 bands, choosing currently from 80, 40, and 20 meters. check it out: www.preppcomm.com/products/dmx-40-transceiver?RU-vidQ
Not only plans, but fulfilled plans! On March 12 and 13 of this year, we introduced the MMX MultiBand Morse Code Transceiver! It has all of the bells and whistles of the DMX-40, a better (lower noise) power supply, and three "slots" for plug-in band PCB's. We currently support 80, 40, and 20 meters. Check it out! www.preppcomm.com/products/dmx-40-transceiver?RU-vidQ
KO4POA...how do we know we are in external mode. Do I hook up to key out to my key input to my external tranciever? Im a new ham and Im still trying to figure this out
Ah, sorry you don't like the music. When we redo them, we will probably just have intro music, but fade it to nothing in a few seconds... maybe bring it back up at the end.
Why did you use such a non standard, as far as Amateur Radio goes, antenna jack? Seems like a BNC should have been the logical choice. Other than that it looks interesting. 73 de KF7VUT
@@timk7749 The SMA connector comes with a PCB edge connector. I don't know of a PCB edge connector for BNC. Of course you can get a BNC to SMA adaptor and keep it attached.
