- In a world of SDR Radio's, let's see how the Icom IC-7800 holds up tuning around 40m and a crowded 20m band. The IC-7851 (the next model after the 7800) sadly will probably be the last of this line up. If the speculation is true, that brings to an end a 37 year legacy that started with the release of the IC-781 back in 1987.
Has the mega-dollar 'big boy' radio become a thing of the past in favour of cheaper to produce SDR Radio's? Let's hope not. - Наука та технологія
Hello Andrew. Thanks for the fine deonstration of the 7800 super station radio. Remarkable find ... my guess is that they did manufacture very many of these expensive radios. Love the big old radios. Interesting to listen to "local" VK stations on 40m. Thanks again. Take care and 73 from Mike VE3XLF.
Great radio! Enjoyed the video - Best of luck with it! 73s
Owned my 7800 since 2004 and is still the best,quietest rx in the shack,not to mention the best built and easiest rig to use ..a true classic !
Was great radio at the time, this radio came with advanced technology and a price tag that made it unaffordable for many , now we have the mini version of IC-7610 and its little brother IC-7300, i believe the IC7300 is well priced for what you are given.
Thanks for a great video.
Thanks! I've also got the IC-7300. Great radio and won't be going anywhere! The IC-7610 is amazing value for money.
Awesome. I love different Base Stations , and the older ones are great.
Near as I can tell, there are no dying breeds in ham radio. I have a Hammarlund HQ-160 communications receiver I still use, an Icom FT-101 I still use, a Heathkit 104 I still use, an Icom 706 I still use, and a couple of (tr)uSDX transceivers I use. That's quite a long history of gear plugged in and sitting on my station desk. I know other hams running stations covering even more ham history. I like to use all of it. I figure there's no such thing as an obsolete ham radio.
That’s a beast!
I’d love to have one of those!
Good Day. What a Wonderful "TOY"!
I wish that I could afford to purchase something like this.
Very good video.
Thank You & Best Regards.
That sure is a pretty rig.
I’m still pretty new. Only been a hamster for a year.
So, these rigs are all eye candy to me.
We were all in your shoes once. Keep learning and working hard. Things will happen more quickly than you expect 🙂
Still a beaut of a radio and still command a high price for an older radio here in the uk for a mk 2
on the wish list cheers from u k
Thanks for sharing what a beautiful radio! I would love to spend some operating time with either a 7800 or 7851! I have the 7300 and 7610 as well. I had the 7300 since 2017 and even though I have the 7610 it’s often easier to fire up the 7300 for listening or for a quick contact plus it uses allot less power than the 7610 ( especially when just listening) but I do love them both! 73 K4BBC
Maybe we have different definitions, but I tend to think that radio IS an SDR - just one with a superhet front end and up conversion in the TX. It's taking the IF, feeding into an ADC and then doing all the IF and audio processing in a DSP before sending the results out to a DAC. On transmit, it does the same thing in the opposite direction - takes audio in and feeds it into an ADC then generates a modulated carrier mathematically inside the DSP and finally outputs it using a DAC.
You make a spot on point! I have no arguments against you and find myself nodding in agreement.
The display looks very much like a newer Yaesu radio display.
I wave at you Andrew from down South (ZS1WC). Thank you for the nice video. What a sound mate. I have an IC7610 in the shack. How would you personally compare the 2 rigs? I think the 7610 is noisier and prone to static and noise we get lately due to solar panels and inverters. 73's
G'day mate, yes by their very design full SDR radios will always fair worse under tough conditions in noisy RF environments. The IC-7800, my Drake TR7A and Collins KWM-2A always beat any SDR radio hands down in noisy environments. Although the KWM-2A is at a disadvantage without a noise blanker. You can still run external band pass filters to help, but the FPGA in SDR's will never compare to good old crystal and especially mechanical filters. That's where the 3khz roofing filter in the 7800 is so powerful especially.
Lovely radio. The only thing that would be distracting for me is the very slow refresh rate of the spectrum scope and waterfall - it looks to be about 2 per second
It can run faster than that (not as fast as a 7300 or 7610) but I deliberately slow the refresh rate right the way down because I like to keep signals in the viewfinder for longer. Just personal taste there.
Most hams can't afford a rig like that. Yaesu, Icom and Kenwood better figure this out. The Chinese will be taking over the market eventually.
That rig wasn’t meant to be sold to most hams. It was top line and it came with a top line price. It would be like telling Cadillac that they better start making more affordable cars for the everyman.
That's not a radio. It's a computer/video game. I'm using an Icom 718, an Icom 728, and a Yaesu FTDX560. I totally rebuilt the 560, and it is my main HF radio. Real radios DO NOT use software.
I also have a similar Yaesu to yours (FTDX-400) as well as many Drake and Collins radios. Personally I think the IC-7800 is the best of both worlds been a Superheterodyne and using DSP technology to drive the Scopes. You can turn the video games off if you like and just use like any other radio, complete with the excellent filtering.
Real radios need to have their plate dipped….but I have also been told to _get with the times_
why do amateur radios have so many knobs and controls compared to commercial professional radios ?
Probably because it's what the market demands. It's not as cluttered as some of the Yaesu rigs!
It’s to do with application. Most commercial radios are fixed mode and locked in to certain frequencies. Focus is on exchanging information. Pick up a mic, say what needs to be said, confirm receipt and clear the frequency. The simpler to use, the more efficient the use of commercial time.
Ham is about playing and experimenting with all sorts of modes on all sorts of frequencies. Tweaking and tuning is required as well as desired.
Back in the day, a commercial operator needed to be someone who understood enough radio technology to tune antennas and finals. Radio officers often would also have to fix and maintain the radio equipment
But yeah. More knobs and buttons === better.
@@MidlifeRenaissanceMan Perhaps its because commercial comms equipment is already optimised so does not need adjustments. For example; 'IF shift' is not required on a high dynamic range receiver with high performance IF filters. These Amateur Radio panels are probably a legacy from the days when radio amateurs built their own equipment and were experimenting with design tradeoffs to achieve optimum performance with limited components.
@@__logan__duvalier__Collins equipment which was the commercial standard of it's time and of the design you were talking about does indeed have "Rejection Tuning" an early version of notch filters. We can debate this until the cows come home, so I'd suggest you make a video of your "Commercial Equipment", upload to your youtube channel and compare against an IC-7800 or similar under tough band conditions. That would be a lot better than just trying to tell me. If you can prove what you're saying, I might just try it! Otherwise I'll stick with my IC-7800 and will be buying the 7851 within the next year.
As a hands on comparison, I had a play with a friend’s Icom M710 marine radio. Support for RTTY, CW as well as LSB, given marine traffic is usually on upper.
Really vanilla radio. Set up was made for channelised marine ops. It had some simple features such RIT, squelch and split
Definitely a dying breed, a modern sdr can do all that and much, much more for a fraction of the cost.
Well now there's a shoot from the hip comment with no logic. SDR's fall apart under tough bands conditions and there's no substitute for real roofing filters. Let's see an SDR deal with an adjacent 30 DB over 9 signal. Add an LDMOS amplifier and bravo, you've got the typical modern ham station polluting the bands with distorted signals today. Full of RF feedback as the smaller SDR manufacturers can't be bothered with RF Shielding and hours of R&D. At least ICOM did that with the 7300 and 7610 (only SDR's I would ever touch from a real radio manufacturer) Last time I tried to tell a guy on air politely that his signal was distorted and he should go back to his Yaesu FTDX-5000, he took it personally and emotionally. Sadly that's how it is with a lot of Ham's these days. Lot's of money to spend on SDR's, no ability for technical debate or troubleshooting. Still I believe in freedom of choice so have it your way. You get what you pay for mate!
No one can win a Multi contest with an sdr, they don't have the blocking capabitily
It is the last of the overpriced poor performance radios, or i should say status simboles! Ridiculous
Too poor to be used by top DX and Contesting stations and to find their way into Government and Military use as well I guess!
Wonderful , i have one '73 PU2XZB
Now that's a radio......
Lovely radio
Would be wasted on me
Besides the Minister for Finance. Entertainment and Shoes has decreed: “No More _projects_ until I either fix or flick all the current _projects_”
I have a workshop full of broken dreams
Sorry to hear mate! Can always try to fix up the broken dreams or at least get as much cash as you can to justify something else.
@@VK2XXL it’s not a bad thing. I’ve got some sweet tube guitar amps that have had the magic touch and are working again. There is another 6 in the queue
There is my old FT101B where B is for Boat Anchor that is itching to get on the air
There is also the house to fix up, the old 20th century Corolla with the _Anti Theft_ 5 speed box
Then there is the house. Currently fixing up the loungeroom. Taken the acne away from the old lime plaster walls, now I’m fixing the horse hair plaster patterned ceiling. I was patching that up on International Morse Code Day instead of joining in.
I’ll have a lounge room by the end of this week, so I’ll have some time to fix the 3 tube guitar amps that I keep looking at….after I sort out the switching between the QRM Eliminator and the old Yaesu FT747GX which is in bits on the bench….
It gives my life purpose. Never can I say “there’s nothing to do”
Last of "mega dollar big boy radios"? Wait till the PW2 amp gets priced in the USA. It is 20k pounds in Europe. de K2XT
