Video

Thanks for your comment and appreciation, to respond to your questions : 1) I am not sure I understand correctly your question but the way I use to do it was to track myself first, this is where I can adjust the RIT accordingly so I can hear myself. Then I can track other stations with the VFO wheel. 2) There are stations how do NOT have doppler control and they track everything manually so in that case, It is going to be difficult for you to tune on them because they are always shifting on frequency. I don't know if I ansered your questions but thanks again for your appreciation. It took a while for me to make that video and I am always grateful when other find the information valuable.

That is awesome ! Thank you for your kind comment and I am glad you found my video helpful ! Enjoy your tuned 7300 !!

23Hz is quite a lot on SSB, clearly audible, no wonder why you needed to use the RIT to hear everyone on frequency !

Thanks for your comment ! I hope we will get such activity in the upcoming months !!! It was a fun mode to experiment with !

thank you for your appreciation !

thank you for your appreciation I'm glad you found the information helpful !

I did calibrate my nanovna with the usual OSL method and this is what I got in the video as per the instructions.

I don't think so since it's "line of sight" direct communication, we are not using those layers for getting to another terrestrial station. That comes directly from the satellite. Solar flares might impact reception though. But that is my interpretation. I might be wrong...

you're welcome ! glad it was helpful !

you're welcome and thanks for your appreciation !

awesome, thanks for your comment ! I made another video demontrating the attenuation factor and it is quite effective well below 20dB, you can find it in my ham radio playlist ! the balun as been installed on a small compact 2el yagi that cover 40/20/17/15 and it works wonderfully well even at 600W+. 73 !

I understand all of what you are saying. My goal with the SWR testing is because I had unkown PTFE wire and I wanted to see if it would have a bad mismatch of impedance. I KNOW this is NOT the goal of a balun. I have another video where I do test the common mode attenuation and it is really efficient and this mode of wiring is well documented for a proper choke. Last thing I would need to check, as you mention, the efficiency of the balanced work such device provide. I will look into it. If you read the video description, you will see where I got all the info from Peter's TRX Bench where he got all the info from Wolfgang DG0SG www.dg0sa.de/ now your turn, all in German. A LOT of information about baluns, chokes and measurements. Family graciouly left Wolfgang website up after he passed away. 73

thanks for your appreciation !! back in the days, I could not do really long videos I guess I could remake that one for many hours ! Glad it helps you get to sleep !

so the resistors are there to load the balun choke to the proper impedence and have the proper measurements. Since it is a 1:1 balun choke, it requires 50ohm load. If you look at the description, the link explain what value resisitor is needed depending on the radio of the balun and how to correct the gain of measurements.

Hello Herbert, when you do not use the -vvv switch, rigctld get connected but you get a blank screen, if rigctld would not connect, you would see an error message or rigctld window would shut off. There is another important thing is that the FT991A is NOT a dual band radio and cannot be configured as seen in my video. Your 991A would be setup as Simplex TRX for the radio type. In that mode, it might work a little bit clunky because rigctld has to monitor when you press on the PTT so it changes band and when you let go the PTT return to the other band. For that to work, you need to set PTT status at Read PTT. I am not sure how this will work with the 991A as I have never used one. But my guess would be to change the configuration in gpredict. I think your rigctld works if you see the status ok when the -vvv switch is there, if you remove it, it will also be connected but won't show it to you. If you want to see more, you get set a -vvvv or -vvvvv, I would not recommand for regular use because it generate a lot of diagnostic stuff but just for the sake of it, you will be sure you see activity and rigctld talks with your radio. Good luck, I hope this will work for you ! Claude VA2CST

@@Aleziss Hello again Aleziss, you have done a fantastic job on your video here. I tried the older version of rigctld 4.0, still won't work, but now I get the message "main: #0 vfo_mode=1" so I moved to the SatPc32 platform and it is working fine on CAT with my FT-991A. Thank you so much for your time and your great video.

@@roboticsdiy390 Sorry you could not make this work with your 991A, another user in the comment section seemed to have some success with my procedure and FT991A but as long you find an application that suits your need that's great, you figured out a way to make this work. I just to like satpc32 and wanted to find an alternative to that old clunky software and I did my best at describing how to do this. Seems other people liked your move to go with satpc32 but thanks for your appreciation on my video. If I ever find procedure with the 991A I will reply here. 73 !

Nevermind. I red the captions

No problem, thanks for your appreciation ! I would be awesome to have such satellite in working order, hopefully amsat will go ahead with the golf project, then we will be able to have awesome contacts for many hours at a time ! 73

@@Aleziss Ive been bitten by the satellite by bug, so I'm going through everything I can on them. Thanks for posting. 73

@@KC9RXP you're welcome ! I was really active in 2019-2020 but I feel I have made everything possible on satellite, only leo sats and a single one that sometime touch europe and my part of Canada for 4 or 5 minutes... If the GOLF project goes on, we will have AO10 style satellite again... there is also plans to have satellite around the moon and a repeater on the moon but not sure that will happend... 73 and have fun on satellite !

if it is the case, I'd like to know in which one and at what date ! If they are, they never asked me any pictures and I am not aware of my cars being in those magasines, if you have information, I would check that out ! Pictures of my cars were once on a car audio website where I use to buy some stuff, if they did it, they have stolen pictures from there and never ask me permission !

thanks for your appreciation ! I did the calibration from 3.5 to 29.7MHz using the aligator clip you see in the video, did the open, short and connected the 50 ohm dummy load on to the aligator clip. It is not super precise but I think it is giving a good idea of the performance of the balun and specially I could compare both the original balun and the one I did build (which works way better than the original one). I would not use aligator clips on higher frequencies, even at 29MHz I could see the reading started to derail a little bit, maybe half of a dB error but for what I wanted to test, i'd say it is not a big deal and it will give you a rough idea on the performane of your balun. Have fun testing !

You're welcome and thank you for your appreciation ! Many computers are thrown in the garbage because of the mechanical drive failing or getting extremely slow while the computer is powerful enough. You will enjoy your computer like never before ! Even when it was brand new it never had that performance compared to a M.2 drive! Best update ever, I still use my computer every day and it perform exceptionally well ! Enjoy your "new" computer !

thank you for your comment, it works really well, it's been installed on a small compact 2el yagi that covers 40/20/17/15/10/6m. I have made another video where you can see the common mode current attenuation and it is really efficient only with a single core.

thank you very much for your appreciation ! It means a lot to me, I worked hard to make that video so I hope it will be helpful for you to run gpredict on windows. 73 de VA2CST

true ! it seems that video helped quite a bit of users so I'm glad I uploaded it and just left it there... we never know...

yep those were great years for car audio and music !

Yes I know and I took care of specify it in the video description from the begining, not many people read that information though. I also shared the german information from Woflgang website url even though he is SK, his family left the website up so information can still be share around the world.

at Bell ??

this one was clean because he was really loud and strong station... when it is a lot farther away, it is way tougher to understand... way worst than cart titan !

no it is wound around a 2.4 inch ferrite core mix 43

it is for areas with fiber infrastructure only at this moment...

thanks man ! I really enjoyed clean installs and HQ sound systems !

that is cool !! I always wonder how good ham radio communication would work in a plane ! the day it happened to me was totally random and luck ! I did a contact with a station, talked for a couple minutes and the other station told me I could take the frequency. I logged the contact in qrz and started to read some stuff while keeping the radio at that frequency and I heard the /AM station in Germany ! I wasn't sure of what I heard, I waited a moment to understand clearly what he was saying and other station quickly responded before me but I was there when he did his first transmission, I wasn't just sure of what I heard ! You having a friend who can do test like that is so cool ! I hope to be able to pick another /AM station one day ! that was a fun contact !

Haha ! Nope ! AMC, Chevrolet and 3 Honda accord !

what version of hamlib are you using ? tryi with the version describe in the video, I also had difficulties with newer releases

@@Aleziss it is hamlib 4.4. sorry i misspoke, it should have said when rigctld opens.

@@TheKiltedHam try with v4.0, this is the one I am currently using and it works perfectly, it should also work on your end too since we have the same equipement !

Hi, at the end of the video, you can see the full list of supported radios by hamlib, scroll the video until you find ICOM and you will know if your radio world with hamlib, of it does, that should work

@@Aleziss do you have that list in print?

@@TheKiltedHam it's acutally in the rigctld help switch, it will show all compatible radios this is where I got the list from

@@TheKiltedHam I think if you type rigctld ? you are going to get all the available switch option, there is one with all the radio list

Hi Gregg, thank you for the nice comment ! it's sad that they are never on the air anymore, they just do voice contacts with schools these days and the FM repeater is a mess here, everybody talk ontop of each others... I also did a nice contact with MIR space station with the actual QSL paper card as confirmation, not too long before it was destroyed ! Those were pretty fun days in my ham radio journey ! 73 de Claude VA2CST

Bonjour Didier, c'est possible que tout soit correctement configuré mais que la version de hamlib que tu utilises te cause ces problèmes... J'ai eu plusieurs commentaires que les versions récentes de hamlib ne fonctionnent pas toujours en suivant ma procédure et je ne sais pas pourquoi... Ça serait peut-être à vérifier en prenant une version plus ancienne, tu règlerais peut-être ton problème. La version utilsé dans le vidéo était hamlib 4.0 (Backend version: 20201018.1) est c'Est toujours celle là que j'utilise puisque ça fonctionne correctement, j'ai pas vu l'utilité de faire de mises à jour. Merci pour ton appréciation !

@@Aleziss Merci beaucoup je vais essayé cela ..C'est vrai que j'ai pris la dernière version mais je vais en prendre une plus ancienne pour voir , je te tiendrai au courant..en attendant encore merci pour cette vidéo. 73

Thanks! Saved me.

well, I do think there is a battery inside your garmin device, it might be a problem if the battery isn't keeping it's charge that it loses it's calibration... I am not sure about what I say here but if your gps does not run for long on battery, that might be your problem. At least you now know how to calibrate it ! thanks for your comment !

@@Aleziss oh yeah, full charged battery in my Garmin is 10 minutes of GPS, but on full charge it can idle for like 2-3 months, so I will try to keep it charged, thanks for the answer!

@@det0xix you're welcome !

Well thanks for your comment! Hope it reminded you some nice souvenirs !

about 800W no problem, you can stack two if you need over 1.5kW

possible, still got 20dB+ of attenuation when I tested that choke with the nanovna, it does the job ok for my need... I think mix 52 is better for higher frequencies but to the detriment of lower frequency, the antenna I currently use run from 7 to 50 so no need for me to go below 7MHz so I might try one day with another core... but I paid 5$ for a single FT240-43 and now they are 15$ a piece... I should have bought much more back then, same goes with the other mix, price have sky rocketted over 2 years only since there is a lot of demand for those cores

@@Aleziss as we are not able to use the 6m band a lot anyhow😁

@@on2mvh937 yeah specially in my antenna, it is only a dipole for 6m so not much efficiency but there is a "big gun" station in my province that run a 6el 6m on a telescopic tower and he makes many contacts every day so I guess we are too cheap for 6m hihi !

you're welcome, I'm glad you found my video helpful !

hmmm I don't think it will work, the connector had a special form that let the eSATA cable connect, you cannot connect an eSATA cable in a USB port, it simply won't fit, mine has a special design and it is identified as USB/eSATA... just so you do not damage anything...

@@Aleziss thank you for your response. No I wrote my USB should fit into the eSATA port; the motherboard I am looking to buy has a "Powered eSATAII/USB port"; similar to yours, but it seems it will be limited at USB2.0 speeds.

@@hitbm4755 ah ok, I missread that, at least you did not do what I thought you were about to try !!

@@Aleziss haha no thankfully not!😂

Hi Leo, unfortunately I do not test with the 991. I am not sure the 991 has satellite mode though so not sure how this will work. If it does work anyway, it should work the same with the L button active, use the RIT on the 991 to fine tune the receive end only and not the TX. If the 991 has no satellite mode, I am affraid it is a different configuration that is required. I'll see what I can find about the 991 but it will be difficult since I do not have one to test.

Last but not least, a small addition .. I know, of course the 991 is not a duplex radio but you can set it like that ( doppler functions: also during transmission the corrections will be executed, it works then too ). For full duplex to use a second (t)rx. As far as everything works very well for VHF / UHF satellite and it may be worthwhile to work with the (CLAR) function and the L button in gpredict ( as with 9700 RIT ). But can not find a adjust / configuration method for the 991 that this works. Also I tried hamlib versions above 4 and -x 1 in the configuration files ( rigctld ) ..

@@Leon55494 I suppose you have configured gpredict that it is not full duplex right ? I've seen gpredict work with non satellilte radios with vfos being swapped when transmitting, it was working correctly.

continued : anyway, when using the L button (here) always within the cycle time is switched back to the basic values transponder frequencies .. regardless of the CLAR function, I wonder if this could be due to the configuration of the 991 something I have overlooked

@@Leon55494 it reset the CLAR value to 0 at each refresh ?

if you open the case and see the M.2 connector then I am pretty sure it will work.

thank you very much for your appreciation of my tutorial, I've worked hard to make this as clear as I could... it was difficult to make it short but I did my best so thank you again for your nice comment. as for the revision of hamlib, I too have problem with other version, I would have to investigate why this is happening. Maybe some parameters have changed like setting "civ transceive" to off, maybe with newer version, you need to leave it on... Since it was working, I never touched hamlib version to newer versions but if I do find out why this is not working with newer version, I will add information in the description box. 73 de VA2CST
