PGXL tuning solution memory

Les Brown
Les Brown Member ✭✭

I received my TGXL and have been setting it up. I have questions about the tuning memory. I understand that you can store up to 20 tuning solutions per band. My questions are:

1) What happens when you try to store a 21st solution on a band? Does it remove the oldest solution or does it remove the solution at the closest frequency to the new 21st solution?

2) How can you find out how many tuning solutions you have stored for a given band?

3) Is it possible to delete the tuning solutions for a given band, or a given frequency?

    Sorry, the discussion should be titled "TGXL tuning solution memory"

    Hi Les,

    Which model Tuner Genius? SO2R or 1x3?

    The 1x3 supports up to ten memories per band up to three antennas per band. You set which antenna ports are active on each band.

    The SO2R version when coupled with the Antenna Genius products will allow up to 10 tuning memories per antenna / per band with up to 4 antennas with tuning memories per band.

    I do not know when you try tuning the 11th memory if it overwrites the first memory or closest.

    you do not need to use all ten tuning memories for each antenna, depending on the antenna’s SWR. If an antenna has a range where the SWR is fairly resonant (under 1.3:1 for example) you can have the tuner automatically go into bypass for that range, therefore you do not need as many tuning memories. Also for antennas that are fairly broad banded you may only need 4 or so memories.

    Here is an example of how I use the tuner on my antenna I use on 80 meters. It is not resonant anyplace on the band. Since 80 meters is 5 MHz wide I used all ten memories for that antenna. I started at 3.525 and tuned every 50 kHz (3.525, 3.725, 3.625, etc) all the way up to 3.975 MHz. That is ten memories. Now wherever I go in the band SWR is below 1.4:1.

    For my 5 band Yagi I programmed portions of the band to bypass the tuner for ranges below 1.3:1 SWR. On 12 and 17 meters I used two tuning memories since the bands are small.

    You do not need to tune every 10 kHz or 20 kHz like other tuner manufacturers suggest.

    To clear the tuning memories completely, you can reset the tuner, which also resets the configuration. Make sure to document your settings when you set it up, but it is straightforward to configure if you do reset it. To reset the tuner, turn off the power switch on back of the tuner. Hold the Operate/Standby button on front panel and turn on the power switch. Continue to hold the button until the front panel (or app) shows Config Reset. Then go back in and configure the tuner and retrain the tuning memories.

    Hi Dave,

    I have the SO2R version. According to the preliminary manual, clause 6.3.1.4, "Up to 20 solutions, keyed by frequency can be stored for each band".

    In clause 5 of the preliminary manual, the following messages are listed: Manual Tuning, Tuning Saved, Memory Cleared, and Config Reset. I am thinking that the message 'config reset' would apply if I do the reset procedure you mention. What about 'memory cleared? It seems that there must be a way to clear the stored tuning solutions.

    I understand the tuner bypass for a resonant antenna. For me, the issue is really only with my 80m Optibeam Yagi that uses relays to resonate in 4 different band segments. It seems that you can only pick 1 segment to bypass. I don't know of a way to make the Tuner Genius understand that it is like 4 different antennas for the band, so I'm stuck with needing tuning solutions across a wide frequency range. I did manage it with 20 tuning solutions, I believe.

    But my 3 questions still apply. Likely someone at Flex or 4O3A will need to answer them. Thanks for your input on this and thanks for helping me with my node-red issues.

    that was a preliminary manual. I was told it is 10 memory tuning solutions per antenna per band.

    I have an idea that might help you. What are the four segments for your 80 meter antenna? In other words for each relay what is the start and end frequency and what is the SWR at edge of each segment?

    you could use Node Red on a Raspberry Pi to switch the relays to change tuning on the antenna then maybe two to three tuning points in each segment can keep SWR under 1.4:1

    Something worth discussing as the Tuner Genius is excellent and maybe that could work for tour station

    you can contact me direct if you like

    To confirm it is 10

    memories per antenna per band with

    maximum of four antennas per band with tuning solutions. The exception is 160 meters which allows 20 memories per antenna.

    the Config Reset is the only way to clear memories at this time That may change in the future.

    Dave,

    Thanks again for the info. For now, I guess the quickest way for me to clear the memories is to do a factory reset. I did a sweep of the SWR for all of my antennas to figure out bypass bands. Now that I know it is 10 memories per antenna per band, I'll redo my tuning solutions. I was way too aggressive the first time, setting the tuning target to SWR = 1.1. Some of my resonant antennas don't get below 1.3 or even 1.5, so I needed to redo them anyway.

    I'm having another problem with my PC with the Flex software at the moment that I need to figure out. The display is getting randomly mangled with blown up font sizes or no refresh of the display. I'm not sure if this is related to recent windows updates or the installation of node-red. It only happens with Flex software windows.

    After I sort that out, I'll talk to you about using node-red to select tuning for my 80m antenna. I ordered a Raspberry PI 4, which should arrive Monday. I decided it best not to load up my PC with anything more than necessary, and I'm still learning the hard way to do regular backups.

    Ok, did you ever have version 3.2.31 installed in tour radio? In the release notes it mentions possible radio database corruption with that version. If you have issues due to the database corruption with 3.2.31 there is a procedure in the release notes to reset the radio and restore profiles from prior to 3.2.31.

    No, I went from v3.1.12 to 3.2.34 and then 3.2 39. It's a strange display update issue. I submitted a ticket with a bunch of screen captures to see what they think.

    Ok, Help Desk at this point is best way to go. Hopefully something easy.

    Dave, WO2X is an Alpha Team member and is well versed on all things Flex, including internals. At the moment, he is our leading expert for the TGXL and he knows where to escalate as required.

    If you are having a problem with the TGXL, do not hesitate to open a support case. Keep in mind that the TGXL firmware is under daily development as well.

    If the TGXL FW changes frequently. Where do we go for updates?

    Peter

  • Mike-VA3MW

    They will be released once Alpha and QA Testing is completed. We will notify you when this happens.

    Ok understand.

    regarding the PGXL radio interface I read the TGXL FW contains a complete rewrite and the new interface works well. I’m interested in knowing if this will be adopted for the PGXL?

    if the FW will be but obviously isn’t available now can the TGXL drive the PGXL to the correct frequency?

    thx

    Hi Peter,

    Sorry for the delay, I was up at ARRL HQ yesterday which made for a long day with travel.

    What exactly are you asking when you state "can the TG XL drive the PG XL to the correct frequency?" Both the PG XL and TG XL get interfaced to the radio for frequency and band info. The tuner does not send band info to the amp. What is your station configuration with radios?

    Ok you answered my question.

    I am driving the PGXL with two Icom radios. 7610 and 7851. The Icom CAT data isn’t read properly by the PGXL. I’ve been through the help desk. Elsewhere up here someone told me the radio interface was completely rewritten for the TGXL. I’m hoping that will be ported over to the PGXL FW.

    I’ll have my TGXL tomorrow and am looking forward to seeing it correctly follow the radios

    again you answered my question about how the TGXL and PGXL work together so thanks for that


    Peter

  • David Decoons, wo2x

    You can change the radio's CI-V address to work with the PG XL. You can now use Icom 7000, 7800, or 775 CI-V address.

    The TG XL will accept any CI-V address.

    Something I'd like to see in some future firmware upgrade. When frequency memories are saved in the TG-XL, small indicators show up on the SmartSDR screen corresponding to each saved memory; perhaps color coded for Ant 1, 2, 3 for the 1x3 model, and A and B on the SO2R model.

    I have to ask this question, just to understand the thought here.

    Can you elaborate on why this feature would be required? What advantage would be gained? Would it be just a ‘nice to have’?

    (I’m trying to ask in a curious nice tone :) ).
