Евгений добрый день!, подскажите как активировать кнопку выбора поддиапазона LFMF для возможности работы в диапазоне 136 кГц (2200м). В режиме "extendet" на передачу ниже 200 кГц не работает передача, точнее все включается есть тон и переход в режим TX, но на выходе уровень 0.
Hello, I have a question about Thetis SDR software and I hope you can help me: I installed the software and waited the remaining 15 min while the DOS window was displayed and the Thetis program opened normally but it didn't work. didn't last very long... When I wanted to close and reopen the Impossible software, it blocks and a sound from windows sounds :-( Disappointed I wanted to see the program!! I uninstalled the software properly using Revo uninstaler and deleting all registry keys in the Windows registry to try to renew a new clean installation of the software... Impossible!! The software seems to install but when clicking on the desktop icon to launch and initialize the start of the program !! No effect it blocks and I no longer have this DOS window present during the first installation ... What to do, do you have any solutions for me because I do not see myself doing a complete formatting of my machine for the reinstallation of this software ... I would rather repair Windows correctly ... Is it possible for Windows to crash when installing Thétis? I look forward to your responses please thanks in advance Cordially
@@RZ3QS Good morning, Thank you for your quick response... But I'm really disappointed that I can't install Thetis again... Here is my problem I tried to delete as cleanly as possible and all the folders and files possible from Thetis in the Windows disk under Windows10 But the problem persists... I tried your method again but still the same! During the new install it hangs when I click on the desktop shortcut sending me a windows beep but without an error message ... When I check in the folders I just observe the Open HPSDR folder but not the second one the place indicated in your file!! I think it's here that it malfunctions because I think files are missing because I no longer see the starting DOS window during the very first installation ... What to do my dear friend of the radio? Do you have other solutions please!! Because I absolutely do not see myself doing a complete reset of the computer !! Too many things and then I said to myself that I should have done a full system backup before installing Thetis... I think that in my HDD disk that harmful files are still present for a new install of Thetis and that's the problem because all my other programs installed before on the machine work correctly Please bring me another solution so that Thetis works again and I thank you deeply for the first advice 73's
@@RZ3QS Good morning, I still have the same problem... unpacking and installing the installation file by the installer is done correctly... the desktop icon is displayed correctly... I have the Open folder fine HPSDR which is present with all its files as you represent in the document !! but I don't have the second folder in the other path!! when clicking on the icon it launches the program window in blue and this window blocks with a Windows sound !! it is therefore impossible for me to go further and see the DOS window appear as at the beginning of the very first installation!! same installation and reinstallation does absolutely nothing ... It's a Windows problem that blocks the rest I think but which one Did you know?! Do you have any other solutions?? please
There is a reserved IPEX RF socket, near the BALUN position, which can bypass the 64M LPF at the input end to achieve undersampling. More information about the interface description of TRX_DUO can be obtained here drive.google.com/file/d/1_PL2uzQUZsRnVVM2YfEZz9fLbAYRF3bT/view
Do you know how to amplify the output from a TRX DUO transmitter? I have seen an inexpensive RF amplifier at AliExpress that might produce a couple watts of output, but it has no filtering, which I am afraid would generate too many spurious signals.
Здравствуйте Евгений. Недавно удалось достать TRX-DUO. На средне волновом диапазоне прием коммерческих станции с большими шумами. Прилагаю короткое видео. Это ожидаемый результат или у меня дефектный TRX-DUO? Спасибо! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1TWslLsgMYQ.html
@@RZ3QS Спасибо. Запустил на 14 мегагерц без антенны.. получается -130дб порог шума.. как то не реально. У вас - 120. Моя прошивка стоит новая от Franko Venturi Linux Alpine 3.19 она использует все 16 бит (в отличие от 14 от Павла).. также пробовал прошивку от Павла прием АМ был также с большим колличеством шума. У меня нет источника сигнала сделать калибровку. На порог шума не калибруется. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-izWk5m5grtI.html
@@RZ3QS Понятно.. NanoVNA вряд ли калиброванный источник, непонятно какой у него уровень сигнала на выходе. Буду полагать что TRX работает и прием AM осложнен наличием QRM в зоне приема и зеркальными помехами. Попробую поставить полосовой фильтр на входе для теста.
@@RZ3QS Спасибо за обзорчик. Мне интересно а периферию можно аналогично подключить как в Ред Питая? По i2c расширители 16-ti jan I2C SMBus I / O для подключения коммутации HPF, LPF. Так же интересно как согласованы уровни на, аналоговых входах для измерителя swr?
@@RZ3QS Особенностей в работе в отличии от Ред Питая пока не заметили не каких? Смотрел Ваше видео по плате коммутации перифирией там так понял stm контроллер общается по i2c с ред питаем?
