Re: W2 wattmeter support

#122

Hi Dave, Hay got the Elecraft W2 Wattmeter today and got it plugged in with the included USB serial cable BUT I am not getting anything coming?out of the W2 to the FLow wonder when you have a minute you could poke around here and see what I have wrong that catch's your eye. The USB serial cable shows connected in the flow and nothing popping?out looking at the Debug for that Flow?

Phone number here is 4357499012?

Thanks a lot

My display flow for the wattmeter is based on the decimal spacing returned from the F command, F00125D2; would be 1.25 watts. And if the third place in the information string is 1 then meter scaling is set for 0 to 2 watts. I was able to do some pretty cool stuff.

I just need guidance on what people want for control of the meter.

I use the metering in the KPA1500. I kept monitoring and control simple, to what I need for remote operation. But the nice thing with Node Red is any avalable command or info returned can be displayed. It is just how crazy you want to go.

For the people new to Node Red, install it and load some flows to look at the different nodes ?nodes to see how we manipulate the data. Looking at examples helps to learn.

As always, ask questions here. Pretty much any equipment with serial, USB, or IP can be added.?

Having used a W2 until last week (but for about 10 years previous) I found that I needed to hit 'scan' more than once.

Changing scales requires you to do math on the reported values.

BTW, for Scan, I think it requires a special firmware from Elecraft, but you would need to confirm they actually made the firmware public.

Hi Santiago,

Hope you are progressing with Node Red.

What wattmeter do you use now? Does it have connectivity either via serial or USB?

Hi all,

I have finished the display portion of the W2 wattmeter flow.

What control functionality would you like to see? Forward power meter in auto range or manually set? (I personally like auto range).

Sensor auto scan or manually selectable? Or a choice between the two?

What other controls?

Once I get some feedback I will be able to have a flow publicly available to test.

Hi Kevin,

Check out my flows in the file area on this group’s site. Read the readme which describes additional nodes you need to install and how to do it. Feel free to load up one of my flows to see examples on how it works. I have comment nodes (in white) for areas requiring customization for your particular station (IP addresses, etc).

An updated W2 watt meter flow will be posted later.

Re: introductions

Very nice looking!?

Tomorrow I am going to revisit the parsing of the rfpower= slider value for current TX band. I thought about it earlier and have some fresh ideas.?

When you do a C44|sub tx all on v2.61 or newer firmware radios it returns all info in the TX Band Settings table so there are entries for rfpower= for every band. To top it off the stream returned can be broken into several streams and not always the same lengths or positions in the stream. I need to look for band specific info for the key phrase for parsing, then count the number of characters for the start, then number of characters to actually parse.

I mention this for those not familiar with parsing so they may learn.

I ran into a similar situation when we upgraded our 9-1-1 system here in the County back in 2009 (I was Technical Manager for the County 9-1-1 center). New Jersey uses the Zoo ALI format for ALI info (the name, address, etc info tied to your 10 digit phone number). A residential call ALI length is different than a cellular call. Also position of the fields shifts. The vendor’s parsing software was written for parsing by start position and length of field. I worked with them to rewrite the parsing to use line/start/length, but also use different parameters based on parsing the call type first. Just some background info.

The part of Node Red I find challenging and actually enjoy is learning the different nodes and all the ways to do things with functions. I need to learn node.js as it is very powerful in its capabilities. (And I am supposed to be retired!)

Re: parsing characters after specific text in a string - ideas?

#113

The issue is the messages are not always the same length and the word rfpower= appears over 10 times. I need to look for a unique keyword for the portion pertaining to the transmit slice.?

The other option I have is to get band data from my amp flow (80 for example) then do an if then function where if (band == 80){

Msg.band = 80

}

Do that for all bands.?

Then look for band 2 in the stream and then parse the Number after rfpower=

Since the length and contents of the messages from the radio vary that is probably the best way.?

Hi Gary,

?

I have not gone back to investigate it since posting the question.

?

The radio returns rfpower= for the current TX slice plus every band set up in the TX Band Setting table. I want to parse only the TX slice power slider value.

?

I have an idea and can test tomorrow. Have to do some volunteer consulting for my former employer this afternoon.?

Re: UDP / GHE

#106

Indeed. I have a Green Heron Select 8 antenna switch (not using it wireless but with a RG6 run from roof to shack) with a GH Wireless Base. I use the GH software configured with automatic band switch using the N1MM protocol, which receives the frequency information from the my Flex 6300 thru the Node Red flow made by Dave. This have been working correctly since I deployed it and never have stopped working.?This same flow sends the same information to a HF Auto tuner for band switching.?

The flow gets the radio info from the Flex and then sends it to GH Software (N1MM port) for automatic antenna switching according to band.

I?m available for any help as far as my knowledge allows me.

Regards,

Santiago

Since I'm looking to incorporate this into a multi op contest station, I'd really like to chat with someone that has it operational with GHE to see what limitations it has and how it would work across my network. If anyone can assist with schooling the clueless, Send me a FB friend request Ron Koenig (Pic of NO Please COPY)

Once you haveNode Red loaded you can check out the file section here

/g/nodered-hamradio/files/wo2x%20flows

Read the readme on how to add the additional nodes I use in my flows. You should load the VITA49, FlexRadioV2, and HF Auto/GHE flows. Reboot after loading the flows. You will need to set the TCP address of your radio in the FlexRadio flow. There are comment nodes in various flows that describes anything that needs to be customized.

Hot to get up and running with Node Red - hardware and software

#104

Hi All,

I am running Node Red on a Raspberry Pi 4B 4GB model with 32 GB microSD card but it should run fine on a 3B or newer with at least 8 GB microSD card.
I have killed 3 Samsung microSD cards (they heated up and cracked when in a SD to microSD adapter in the PC. Not sure why but the cheap microSD cards from MicroCenter (no name brand) have been working in several Pi's (Node Red and PiStar).

Software -ah yes... Here are notes that I have taken while building a Node Red Pi last week. It is not formatted yet but I know there are several people who could use some help getting started. So please feel free to comment as you go through it and we can work together to make it more complete then put it on the site WiKi.

Have fun and ask questions if you need help.

Type y and hit Enter at each prompt. It will take several minutes

Once complete type sudo apt-get update and hit Enter

When it completes type sudo apt-get full-upgrade and hit Enter

Type sudo systemctl enable nodered.service and hit Enter

Type sudo shutdown -r now to reboot the Pi. Node Red should automatically start.

?

When the Pi reboots and Node Red starts open a web browser and enter the IP address if the Pi followed by :1880 (that is colon and 1880).

It will bring up the Node Red editor

You are now ready to create or import flows into Node Red.?

Some flows require additional nodes to be downloaded and installed.
