November 14, 2024 Yaesu FTDX-10 The less is.... more
Receiving S9Z from São Tomé and Príncipe.
I have a tall mountain very close to me in that direction, so signals are weak.
AMP1 has no amplification, AMP2 amplifies both noise and signal, thus no real improvement.IPO decreases the amplification down to the point to cancel the noise. Real improvement.
At the end with just 50 Hz of bandwidth there is some ringing.
The external loudspeaker, an old Kenwood SP-230 is kinda deaf, so the AF amplifier of the radio cannot produce a loud sound.
Further tweaking with the RF control could produce an even better result.
Bottom line is, what matters is not the S meter reading but to produce the best signal to noise ratio.

receiving V55LA -Namibia- with a 8m long vertical, 12m up. Temporary set up and filmed with the phone. Not good quality for sure, but it gives an idea. The edge to the FTDX10 comes from the digital Noise Reduction. The Lowe-225 il not really meant for such kind of traffic, but the signal can be read anyway.

    The FTDX10 seems to be the winner. But it should come as no surprise with it's advanced technology. But the older rigs still deserve some respect for being state of the art in their time.

    • @germibestia
      @germibestia Месяц назад

      un ricevitore moderno usato... come un ricevitore moderno è meglio. Nel caso del FTDX-10 il DNR fa miracoli. Tutto il resto dei vari aggeggi digitali aiuta pure non poco, a patto di prendersi il tempo e imparare ad usarli in modo efficiente. Fra tutti i ricevitori professionali anni '70-'90, e li ho usati quasi tutti per lavoro, lo EKD RFT-300 è l'unico che può ancora rivaleggiare con la tecnologia moderna. Di gran lunga il migliore di tutti. Poi vi sono cose strane come i Lowe HF-225 e HF-235 che per la ricezione di stazioni di radiodiffusione AM sono, sia per l'ottimo circuito di sync che per la resa audio, anche meglio del moderno. Ovviamente questo è il mio parere, che vale né più né meno di quelli totalmente diversi.

    • @germibestia
      @germibestia Год назад

      in effetti a quei tempi ha permesso di costruire delle radio a copertura continua con una ottima stabilità. La accendi, ti metti su un segnale, torni dopo due ore ed è ancora perfettamente sintonizzata. Lo stadio d'entrata non è una roccia e tende un po' a intermodulare, ma con poche modifiche si ovvia in parte anche a quello. Oggi quello che da più grane sono i filtri Murata che con gli anni si spostano un po' in frequenza.

    • @germibestia
      @germibestia Год назад

      Ciao Claudio. I Lowe sono ottimi. La genialità di John Thorpe è stata di disegnare un ricevitore performante e allo stesso tempo molto semplice. Ho un 225, un 225 Europa e il 235 e sono tutti pratici da usare. Anche per la possibilità di immettere velocemente la frequenza dal tastierino. Il JRC NRD 61A l'ho riallineato velocemente, ma ha ancora qualche difetto da sistemare. L'audio ha una tonalità troppo bassa, quindi qualcosa nel circuito dell'amplificatore di BF non funziona a dovere. Potrebbe essere semplicemente un condensatore che con il tempo ha cambiato valore. In USB il filtro a 3 kHz non è centrato. Da vedere se è una questione di allineamento o proprio il filtro medesimo che con il tempo ha cambiato caratteristica.

    Hi, image and IF rejections are the weak points of all down conversion transceivers (FTDX101, FTDX10, K3, TS890...). Up conversion transceivers like KWM380, TR7, PT8000, IC7700 were conceived to eliminate this problem. The only goal of manufacturers is to be high in the Sherwood chart, even if other parameters are neglected. Only Icom, Flex, Anan, and now Elecraft with the K4 are using the right technology.

      hard to find a difference between the 3 radios. I have not yet tried them with a large outdoor antenna. What makes a huge difference, is the condition of the radio. We are talking about a 30 + year old device. So most of them by now are badly aligned and with some sort of faulty contacts. So it makes sense to buy one if you know how to service and align it, and have all the necessary instruments.
