Jerry,

When you decide, check out the Main Trading Company (located in Paris, TX) https://www.mtcradio.com/

These people have great pricing, free shipping, the best customer service I have seen, and are really good radio people.  (They have a thing now that if it snows in Paris Tx on Christmas, you will be refunded your money and the rig will be free).  If you find something at a lower price, call them with the information, and they will match any price.

Bought my 590SG there (drove there in person), and was thrilled with the deal, and how they work hard to make sure you are happy.
I am not affiliated with them in any way!

The Kenwood 590SG is a good rig as well.  It's about $1299.  All of the prices I mentioned here are good through the end of the month, by the way, except the IC7300.  It's good through the end of the year.  They're all coupons or rebates of some sort.

I *think* your 1000MP has a built in AC power supply, so you'd need to add a 25-30 peak load power supply in for either of these rigs as well.  100w on SSB voice peaks draws 23 amps (typical of most T'cvrs, anyhow) for reference.

Let us know what you come up with.

Good luck and Happy Thanksgiving!

Im with Barry, I have the 7300 and love it. I had one glitch where I had to replace the Pre Driver at Icom, but that

was only $109.  And it was because my 35 year old Diawa tuner shorted out.  Its only 1 cable to the rig from the

computer for all sound card interfacing. 

Good Luck in what you decide.

PS If I had no money limits I would go FLEX but those are way outta my league.

Jerry,
You asked, so here is what I am using:
uBITX v6 by HF Signals with a Nexus DR-X cross-patch by Budd Churchward, WB7FHC.
I really enjoyed putting together both of these kits and learned a whole lot in the process. The Nexus DR-X is actually the top HAT (Hardware Attached on Top) that stacks on the FE-PI audio board HAT. The FE-PI is stacked on top of a Raspberry PI 3. So you wind up with a little triple-decker. I didn't know anything about the Pi in the beginning. Fortunately Budd's associate, Steve Magnuson, AG7GN, has put together all of the needed software and operating system into an "image" that can be downloaded to a micro SD card. That little micro SD card functions as the "hard drive" for the operating system as well as for data storage on the Pi. About once a week, I use a menu item on Steve's home page of the Raspberry Pi to check for updates. If updates for the operating system or one of the Fldigi components are available, the menu item will perform all of the updates.
My little station isn't in the same league with the big guys, but it is still a lot of fun for a new ham (and new 070 member), like me. By the way, "thank you" to those of you who answered my calls last Sunday. I had a great time and hope you all did, too!


Re: Rig

Jerry N9AVY
 

Hi All !

Thanks for all the replies. Am trying to digest it all. Lots of good info.

Let me say that I plan on keeping the FT-1000MP as long as I can. If repair is still available, it will be done. One of the techs who worked on it said it had one of the hottest receivers he ever saw.

The plan is to buy a newer radio as a back up to the FT-1000MP and for the eventuality that main rig would go South during a contest. BTW, I do own an amp (Ameritron ALS-500) which I used for chasing DX, but with only 3 entities left (Scarborough Reef, North Korea, and Bouvet Is.) . There doesn't seem to be any of these on the calendar so I may never work them, but if the opportunity arises I'll be ready.

Had a 756PRO3 I had found at an estate sale for $600, but I missed the bid (rats!). Am leaning towards a used rig as am on a fixed income now (retired a year ago); so price is a concern.

Anyhow, thanks for all the input !

73, Jerry N9AVY

I use a ICOM 7200 strictly for digital. 
I bought a 7300 years ago when they dropped to under $1000. 
The 7300 has been great for phone work.  Even the internal speaker sounds great for these old ears that don’t hear so good. 
Get good reports on the stock mic. 
Never have owned a amp so always run barefoot. 
Never used the 7300 for digital work. 
The touchscreen is fun to play with. 
But as Milt sez the best radio is only as good as the antenna.

One suggestion? Don't buy a radio that's far beyond the capabilities of your antenna's. You can have the greatest, most sensitive receiver(s) on the market, but all they hear is the mini-micro-nano volts of signal your antenna's capture.

Re: Rigs

Bill Williams
 

When I got my license in 2001 I bought a Kenwood TS-2000 because it filled the HF, VHF and UHF categories in one box but more importantly one price.  I knew it did not have a great receiver but economy dictated.  Since then it has done phone on all those bands, many digital modes including PSK on all of those bands and still does.  I have considered replacing it but would keep it for the digital modes anyway so have not spent the money.  I work very little phone. The radio is almost 20 years old and Kenwood actually made it all that time closing production last year.

My go kit radio is an FT-857 and it has done all those modes also.  No thoughts on replacing it.

For psk and other HF digital modes I have used:
1. TenTec Eagle 599AT
2. Elecraft KX3 and KXPA100
3. Icom IC-7300

Of those I think the KX3 hears very slightly better than either the Eagle or the IC-7300.  The filter adjustments on the Eagle drove me batty, the filter arrangement on the KX3 is a thing of beauty and a delight forever, and the filter arrangement on the IC-7300 runs a close second to the KX3.

The problem with the KX3 is that any setup rapidly devolves into a rat’s nest of cables connecting the Signalink, the computer, the KX3, the KXPA-100, and (if I’m going to use is) the PX3 panadapter.  Plus power to everything.  It’s a nightmare.

In comparison, the IC-7300 has just the antenna, one USB cable to the computer, and power.  Very simple and neat.  The internal sound card works really well and avoids the myriad RFI issues I have had with the festoons of cables to get both rig control and the SignaLink USB connected with the KX3.

On transmit my KK7UQ IMD meter suggests that the KX3/KXPA-100 is slightly cleaner on psk31 than the IC-7300, with the Eagle bringing up the rear but not by much.

In terms of ease of use when you’re switching repeatedly between CW, PSK, and SSB phone, the touch screen and UI of the IC-7300 have a slight win over the KX3 and it’s long list of menu items.

Getting things configured for PSK31 was surprisingly easy on the Eagle, a bit of a head scratcher on the KX3, and a snap on the IC-7300.

In terms of bang for the buck the IC-7300 is the hands down winner of the three unless you are a heavy CW sort of person - the KX3 wins hands down for CW, with better filtering, onboard decode for when you can’t quite keep up or get lost, automatic zero beat tuning, etc.

I am not really a DX chaser so the slightly better receiver on the KX3 most often loses out to the convenience and UI of the IC-7300 and my shack is going thru a reorganization to reflect that.

I’d be super interested in the experience of others with various transceivers.

Hi Jerry,

I have definitely partaken in the Elecraft Koolaid® here.  Love my K3/100 for digital and phone.  Saving for a KX2 now for SOTA excursions.  I think Eric and Wayne are really on to something up there in Aptos.

Too bad about the FT-1000MP.  Venerable rig.

Re: Rigs

Paula K7PAX #1739
 

Jerry, I am trying to decide on a new rig too. My hubby said I could have a new radio of my choice for my birthday. I was thinking the Yeasu FTdx-101MP because it will give me 200 watts - an improvement over my IC-7000 at 100 watts. But someone said if it were them, they would get an IC-7300 AND an Elecraft KPA-500 amplifier, and save $700 over the Yeasu. So I have to ask myself, would I ever use all the bells and whistles on the FTdx-101MP or would the IC-7300 keep me happy, and I get an excellent amp I could use with any rig down the road? I am not a contester, except for casual contests, but mostly like to work digital and chase DX.

That's a shame to bury that rig.  My 1000MP went out last year and I sent it to Technical Specialists in Tampa where Lee does circuit board level repairs.  Might want to send it to him if it ever goes out after you get your new(er) rig.

McIntosh, Deputy Director of the National Center for Atmospheric Research in Boulder, et al., has concluded that Solar Cycle 25 could be among the strongest sunspot cycles ever observed, and will almost certainly be stronger than the just-ended Solar Cycle 24 (sunspot number of 116). The scientists say it will also most likely be stronger than Solar Cycle 23 (sunspot number of 180). As the abstract explains:


Sunspot cycle graph dating to 1700. [SILSO Graphic]

"The sun exhibits a well-observed modulation in the number of spots on its disk over a period of about 11 years. From the dawn of modern observational astronomy, sunspots have presented a challenge to understanding -- their quasi-periodic variation in number, first noted 175 years ago, stimulates community-wide interest to this day. A large number of techniques are able to explain the temporal landmarks, (geometric) shape, and amplitude of sunspot 'cycles;' however, forecasting these features accurately in advance remains elusive.

"Recent observationally motivated studies have illustrated a relationship between the sun's 22-year magnetic cycle and the production of the sunspot cycle landmarks and patterns, but not the amplitude of the sunspot cycle. Using (discrete) Hilbert transforms on more than 270 years of (monthly) sunspot numbers, we robustly identify the so-called 'termination' events that mark the end of the previous 11-year sunspot cycle, the enhancement/acceleration of the present cycle, and the end of 22-year magnetic activity cycles. Using these, we extract a relationship between the temporal spacing of terminators and the magnitude of sunspot cycles.

"Given this relationship and our prediction of a terminator event in 2020, we deduce that Sunspot Cycle 25 could have a magnitude that rivals the top few since records began. This outcome would be in stark contrast to the community consensus estimate of Sunspot Cycle 25 magnitude."

Re: PODXS Club At The Beginning

There are many sites which have little or no history. My local club started by myself and 2 others goes back to 1978, but our "Club Historian" died and everything he had was lost. No one else picked up the job and there are lots of blank spaces through 70s, 80s and 90s - bummer. Club now has over 100 members who are curious...

Good for whomever kept PODXS 070 history !!!

What amazes me about archive.org is that someone had the foresight to start it
only a few years after the WWW was born (the browser part we think of today,
not the text-based internet).  Being able to go back to 1997 is a real gift.
