Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi
If I understood correctly your needs I solved 232->Eth conversion between my Node Red "Acom 600s web console" and the PA via its rs232 port by using an external (cheap) box (). It's really useful and easy to implement by its administration web page. From node red I drive it via a TCP in TCP Out nodes and the module cares of converting into rs232 buffering and so on, absolutely transparent. Unique limitation is that it handles only rs232 Rx-Tx lines (so no control lines). Power it On and nothing else is required. For more details download my flow here: https://www.ik1bxn.it/wp/2025/02/13/acom-600s-lan-web-console-v-2-3-cat-synch-to-flrig-macloggerdx-rumlog-n1mm-flow-cleanup/

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi
Hi Dave.? Been a while.? I originally had the RAAS-8a plugged into a PC and was using WA4MCM application to control it.? It worked well from the PC.? When I plug it back into the PC I see the followed defined for ports.? The Silicon Labs one is the RAAS-8a.

Re: How To : ser2net - Serial to Network Media Converter with a Raspberry Pi
Hi Domenick
Is it possible the USB device is showing as a USB HID device?
The LP700 wattmeter is like that.?
What happens when you plug it into a USB port on the PC?

Version 2.1 addresses a minor bug that occurred when the probability of the predicted R value for 1-2 and 3-5 was the same but very small (e.g. 1%). This brings up a problem with a lot of APIs that I work with. They are not well documented. It's easy to call the API and see what the returned fields are, but often I don't know all of the possible values that those fields can have. This was one of those cases. I had considered doing more error checking on the predicted R value, but having a predicted value of R be 1% for R1/2 and also 1% for R3/5 made no sense to me. The code was modified to handle these fringe cases better.

Craig,
?
Attached is my flow for the navbar.? ?The flow shows the current solar idx's along with any geo magnetic storm alerts.? ? ?It uses OpenWx for the current temp,? wind direction, conditions, and barometric trend (up, down, flat).? You will have to get an api key from them.? ?The lightning indicator shows the current radius and last strike time if the icon is green.? When the icon is red it shows the actual strike distance and updates the last strike time.? ?There is a default configuration in the flow and a page where you can dynamically set the parameters.??
?
? In addition,? I have css code for all the flows in the attached flow.? ?If it blows up please disable the css ui template.? You will have to modify it or use your own template in such a case.?
?

Please see the attached flow

Re: Flex6xxx and ESPHome or ESP_Async_TCP_Webserver
And to add a V3 layer of security, you can use TailScale or other VPN to access the Node Red web page. I do that with both remote accessible stations.?
TailScale works very well.?

You can build each of your antenna switch / rotator boards with a ESP_Async_TCP_Webserver, using websocket and create a simple WEB server to control it.
?
Then you can make a noder-red flow that connects to each board websocket and present it on one web page to display and control them all.
This way you will need just one port to forward and it can be secured.

BTW is your "ex.military FLP PA with 10 electromechanical memories"? from the USSR R-140 mobile transmitter?

Re: Flex6xxx and ESPHome or ESP_Async_TCP_Webserver
It's possible to control it, but you need to design your web page.
ESP_Async_TCP_Webserver with fast websocket is the way.
?
On other hand Node-red is a better way.
I have 3x Tuner / Antenna switch / Power / SWR meters, 3x WiFi rotators and PAmp with a Wi-Fi network based on ESP8266.
Using Node-red and UDP datagrams to collect all the information form all 7 nodes and display it on one web page.

Hamvention 2025 Node Red Presentations
Hamvention is upon us!? Hope you can make the show.? If you want to learn more about Node Red at the show, here are some things you might want to put on your calendar.
?
Saturday Forum Room #4 at 9:15am - Remote Ham Radio.? Mike Walker (VA3MW) and myself will be presenting how to remote your radio, with a special guest on a new product announcement!? You don't want to miss this announcement.? We'll be touching on some Node Red flows within the presentation.?
?
Saturday Forum Room #4 at 2:40pm - Node Red How To.? I'll be presenting a few slides at the beginning of the forum and then head directly into a hands on demo.? I'm not going to side show you to death with this one.? I've already done that and the guy in the front row napping after lunch in the air conditioning made it real clear the slides were a substitute for some Trazodone pills, so we are changing it up.? We'll start with a blank canvas and build some easy flows then we will plug in a KX3 and control the radio from Node Red with only a few nodes.? Easy stuff.? We will also load some flows we downloaded from the files section in this group for a KMTronics 8 port relay board and control the relays.? At the end we will take 15 mins to talk about the Sierra Radio Station Controller Node Red install and talk about some real world uses.
?
If you want to see the full Node Red presentation from years past: https://youtu.be/0G1RXr9k_jA?si=UJiJ37heXNCLK4Kb
?
I think some of the forums will be streamed live and/or recorded for later posting.? Watch the Hamvention YouTube page for those streams. ?
?
Come say hello before or after the forums!??

? I am pleased to release a major upgrade to my Solar weather flow -- Solar 2.0.

On the surface, it doesn't look all that different than the 1.x flow, but under the hood it has been completely rewritten from the ground up. There are numerous enhancements, but the star of the show is that you no longer have to average the data from nearby ionosondes to get an estimate of MUF and foF2 for your QTH. Instead, I am now doing a direct lookup of MUF and foF2 for your QTH based on the sophisticated interpolation that Andrew Rodland, KC2G, is doing on his excellent web site . I reached out to Roland a couple of months back and he graciously agreed to make an API available that will take your latitude and longitude (or Maidenhead grid) and return an estimate of MUF and foF2 for that location. This is much more robust because it does not rely on nearby ionosondes being active to do the estimate and Roland's interpolation routine is more sophisticated that what I was doing. This API works anywhere on the planet and does not require you to maintain a list of ionosondes. Thanks to Roland for this excellent resource. Keep in mind that the MUF you will see is directly overhead at your location, not necessarily the MUF along a path between you and a distance station.
Since we no longer need to display the status of nearby ionosonde's, I repurposed that space for displaying recent X-ray flux data in the form of peak solar flare intensity over the past 24 hours (left number) and 2 hours (right number). In the screenshot shown, the maximum flare in the past 2 hours was a C5.4 classification. This was also the largest flare in the past 24 hours, so the two numbers are the same in this example. The solar flare classifications and the color scheme I am using throughout the flow can be found here:
I have updated all of the readings (other than MUF and foF2) so that they now pull data from NOAA instead of 3rd-party sources. All of the displays have been modified such that the color scheme and thresholds match NOAA standards (as best as I could determine). The space weather conditions R, S, and G (as defined in the link above) have also been rewritten, particularly what is displayed ?for the "Predicted" values. This one has always been tough, since the NOAA does not predict precise values for R and S, instead giving a range of probabilities. This is difficult to display in the space allotted. In the new flow, I do a better job of representing this information. The display for predicted R can be R0, R1/2, R2/3, or R3/5. For example, if R1/2 is displayed that means the most likely peak R value in the next 24 hours will be R1 or R2. NOAA provides less granularity for the S prediction so the two possible values are S0 or S1/+, the latter meaning that the most probably S value in the next 24 hours will be S1 or above. For both R and S predicted values, the display is further color coded to represent the expected intensity.
?
The headings for all of the fields (except for the gauges) are clickable and will take you to a web site with more information about that measurement.
?
As always, check out the README node for information about how to use the flow. In particular, you have to set up some environment variables with your latitude and longitude, otherwise you will be getting the MUF and foF2 for my location instead of yours. If you don't want the header "Solar Conditions", just delete the Solar Title node. This flow was developed and tested with Node-RED 4.0.2, but it should work fine with 3.x.
