Re: Yaesu FT-818ND Discontinued Manufacturing
You have a very simplistic view of the industry - you seem to believe that every hard-won technical advancement beyond superhet receivers with 'slabs of quartz' is a step backwards performance-wise

Re: Yaesu FT-818ND Discontinued Manufacturing
SDR's are pretty crappy for REAL RF rejection. An SDR is taking everything and only tailoring it's output to end user expectations. But at the end the DAY, unwanted signals still enter the "front
Re: Yaesu FT-818ND Discontinued Manufacturing
John, I read the "crazy" product description as in "crazy, outside the box thinking, design", not bad, wrong, or any other way AT THE TIME IT WAS INTRODUCED. He also mentioned the ultra-compact FT-90:

Re: Yaesu FT-818ND Discontinued Manufacturing
Geert How does the FT-817 become a "crazy design" when they probably sold more of these than any other radio of the past twenty years? What data supports this "crazy" statement? If they cannot get

Re: Yaesu FT-818ND Discontinued Manufacturing
Once the Hilbert transform made nearly perfect filter performance possible, using digital processing (at the price of latency), mechanical filters and all their intermodulation issues were doomed. A

Re: Yaesu FT-818ND Discontinued Manufacturing
Nearly all modern radios are direct conversion (I/Q translation) followed by DSP to make the bandwith. The days of a hetrodyne receiver converting to 455kHz for IF filtering with a mechanical /

Re: Yaesu FT-818ND Discontinued Manufacturing
Yet, somehow Yaesu can't source filters for their radios... Yaesu can sell those 'lumps of quartz' for $150/ea, if there was a source, they'd still offer them IMHO Ken, N2VIP

Re: Yaesu FT-818ND Discontinued Manufacturing
A valid question. But I think the manufacturers are illogical. A xtal filter, all you need is ONE lump of quartz in series with the 455Khz signal to make a CW filter. SSB filters actually require more

Re: Yaesu FT-818ND Discontinued Manufacturing
I would think with Yaesu discontinuing the FT818 is more to do with competition and drop in sales. If the rig was selling very well I would think Yaesu would find a way to keep it in production.?

Re: Yaesu FT-818ND Discontinued Manufacturing
What surprised me was the 818 short production run. Most radio models stick around for longer than that.? ?I look forward to whatever will replace it. Yaesu has always had the right HF radio for me

Re: Yaesu FT-818ND Discontinued Manufacturing
"Keep xtal filters"? Sourced from whom, exactly? And they tend to be physically large, forcing certain compromises regarding radio packaging - modern, QRP/Portable radios are built like HTs for good

Re: Yaesu FT-818ND Discontinued Manufacturing
I was thinking more of the form factor. By all means design out the problematic parts, but - retain the form factor - better support for user build battery packs so that we don't rely upon 3rd party

Re: Yaesu FT-818ND Discontinued Manufacturing
I got my FT-817 in 2004 as my first tranceiver. It never had any problems. Since 2013 it sits in my shack as a back-up with a small HF and VHF linear besides its big brothers 'Icom IC718 and FT991a'.

Re: BNC Connector is Loose FT-818
I have used needle nose plyers for such nuts around a RF connector.? Anything where one can force the rotation using both sides at once. But as said getting to the nut will require removing the front

Re: BNC Connector is Loose FT-818
Would a split-ring pliers work on that nut? How about a needle-nose? I don¡¯t have a loose connector, but both of those have worked on that kind of nut on other devices. Kevin N5KRG
