Hi Simon and all, Although I already have the IC-705 which I like a lot, I am keeping my 2 X FT-817 radios because they still work FB and I still use them when I operate portable. They both have minor

Ken Unfortunately the replacement for the FT-817/818 is already on the market. However it’s made by Icom. My 817 won’t be coming on the market any time soon… well while I am alive anyway. Simon

Well personally I love my 817. Had it for many many years. Got the cw filter from some place in Huntsville,Ala. Don't think he is in biz anymore. I take mine on trips to different cites when I travel

Baofengs HTs are SDRs. Ken, N2VIP

Speak for yourself! Ken, N2VIP

Just for information a rig that is SDR does not mean it has tunable filters or newer tech except it is more of being computer controlled.? SDR means the operating system is in firmware and can be

I have often described the FT-817/818 as a perfectly balanced set of compromises, and almost any changes would be viewed negatively by someone in the community (I remember list members that were

Sorry, wrong :) Look at the block diagram / schematics. The IC-7200 is a superhet SDR. Yes, it has traditional conversions, a roofing filter… But the last conversion is a digital stage (at the time

Borja I have both the 7200 superhet and the 7300 SDR The 7200 survived a brief mini tornado downpour whereas the 7300 would have gotten waterlogged The 7200 seems to be a redone 718 but the 7300 has

In that case you completely ruined the compact design and form factor of FT817/818… radio + dsp unit + tablet + another accessories …huh ;) Petr

Or the spark transmitter, or Grandad's special pencil for drawing grid leak resistors… 73, Stay Safe, Robin, G8DQX

The problem is, is there an alternative for Collins filters offering a similar performance at that price point? I got the optional SSB filter for my 817 and its performance is unbelievable. Fitting

As a matter of fact, the optional Collins filters were mechanical ones, not crystal. Not that it matters though. And unless I am very wrong the rest of the filters are ceramics. It is understandable

Hi all, Time marches on – just as well we’re no longer reliant on the coherer! 73….Eric VK2VE. Sent: Wednesday, 11 January 2023 02:08 To: [email protected] Subject: Re: [ft817] Yaesu FT-818ND

Circa 2000, aside from Collins, did you provide Yaesu with a list of alternate sources for 'slabs of quartz', or was Collins the only supplier still in business? So if Collins was the only source for

I called out Yeasu for making one company (Collins) it's own Achilles heel in within it's supply chain. Do you know what an Achilles heel is Ken, and do you know what yours is ? ;-) Goodbye ! 73 de

Has anyone seen anything about Yaesu being able to continue offering repair service on the FT817's ?Rich, W1GBBSent from my Verizon, Samsung Galaxy smartphone

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

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
