Hi All..just a suggestion if your Toyo heater displays E-0..it might be a case of non-grounded generator..for a couple decades I have been using a Monitor 2100 with my generator..no problem..never grounded it since the manual never said it was a must..well our brandy new Toyotomi Laser 731 would not function without seeing a ground..we use HD ext cords..best solution for me was a 4' chunk of copper rod driven in right next to the generator and attached (our generator is outside 8' from the house)
                       Call me a dum dum for never grounding that but in case someone else has this heater..ground your generator !! I'm saying this because we just went thru a whopper of a Nor'Easter..and it can get mighty chilly in the shack..
                                 Take care ya all  stay warm  73 de DAVE WB1EAD

Hi Bill,
Thanks for the suggestion. I had an SDR-IQ about 10 years ago and loved it. Ultimately I ended up moving to a Flex 5000 and then a 6400. I do have an RSP which is set up as my WSPR receiver 24/7 that reports up to PSK reportere. But it is not working now.

So I am comfortable with the radio and set up.

Anyway, I want to free up some space on the AM side of the shack and have decided to sell my TMC GPR 90. I want to replace it with a smaller receiver that will do a good job on AM and SSB to run with my CE 20A.

I am starting to think about a JRC as they seem to have good reviews, but am hoping to get some real world feedback.

73 and see you at NF. No power supplies for sale this trip.

  Just a thought—some might object to tying their radio activities to a computer—(and I get that) but a few years ago I went over to the dark-side and started using an SdrPlay unit, the RSPDX, and I love it. It's about 3.5" X 3.5" square, and I've got mine stuck to the wall with Velcro tape. Using the SdrUno software, I can do things with it that are otherwise impossible with the typical stand-alone receiver, allowing me to keep operating in the face of hardships like deliberate jamming and heavy adjacent spatter, which would have me simply turning off my old HQ-170 and giving up.
  It admittedly lacks the charm of an HQ-170, SP-600, or R-390—in fact it has no charm whatsoever; it's a soulless little black box—but it's a powerful little thing that pretty much goes everywhere and does everything, and it's quite cheap.
  I know—I totally get all the objections; I'm a hollow-state guy, but don't underestimate the power of the dark-side.

The radio in this subject is a Hammarlund HQ-110A. The attached photo is of the piston-type trimmer for the 2mc end of the 160 meter band. It is a 1-8pf trimmer. Note that the piston is all the way in as far as it can go. Does that mean it is a full capacitance (ie 8pf), or is it at the least capacity? There is one wire leading to its transformer. I assume since there is no other wire, that the chassis is the second contact. Hopefull ysomeone can clear up these 2 questions. Thank you.

I am considering adding a general coverage receiver to the boat anchor station. The criteria is as follows

Gen Coverage .55- 30 MHz
Good AM with filtering as well as SSB/CW with product detector
Good construction and technology.
Prefer a smaller footprint, but will consider a larger size.
Would prefer Sandstate but am open to a good tube unit. something like an R4B if it had better AM reception and continuous coverage.
Need not be built by a ham supplier.
Any thoughts?

Shane:

I am sorry to hear of Brandon's passing. While we did not QSO on the air, we did email.

As a fellow ham from Louisiana, there are not too many AM'ers in the Gulf South.

RIP Brandon

Hi Bill:

Looking forward to hearing it on the air. Note that often a Super Senior will trip due to carrier pinch-off (i.e. excessive negative modulation), so make sure your modulation is not too high.

Also about 240 Watts carrier is a good spot to set the power as with +100% modulation, you are not running out of modulator headroom.

See an interesting thread here of our experiences with Peter W1ZZZ's Super Senior a few years ago:

Yes Bruce is a good guy.

  Well, I finally broke down and got myself a K7DYY Super Senior, the 80/40 version, a decision I made with some trepidation, not over financial concerns but rather over concerns that it might pull me away from my interest in my own HB stuff. Little danger of that, I think, and if anything, it might just raise the bar a bit for my own projects, which isn't a bad thing. Mainly, I wanted the Super Senior for my summer rig; I just can't get into running the tube gear on sweltering July and August days anymore.
  So, first impressions:
  It's very nicely built; looking in through the rear of the enclosure reveals what looks to be a modular sort of construction, with the major assemblies each built into their own cast-aluminum boxes. Very nice work.
  The fans are a bit louder than I'd expected, but not terrible. Given the rig's high efficiency and low heat output—even when the buzzard flies far from the roost—I suspect that they could be slowed down considerably with no ill effect at all.
  The SWR protection is very sensitive: I run an excellent Heathkit roller-inductor tuner, and even when tuned for exactly 1:1, I will still get the occasional trip. The trips only occur right at key-up, though, so I'm wondering if there's more going on there than meets the eye. A beep or a bright flashing LED might be nice to warn of a trip, since I'm usually not right in front of the rig, and the small "High SWR" text that flashes on the little LCD doesn't grab my attention. But, as Steve very helpfully pointed out, the REA mod monitor has a "beep on carrier loss" setting.
  The first time I had it on the air, I was getting notable distortion, sounding very much like RF getting into the audio, which I thought was odd, since I was using the very same audio-chain—DBX286S and Inovonics 223—that I use with my DX60 with no RF issues at all. My audio/PTT setup includes a switching/junction box, and I went in and installed bypass caps on all the switching signal lines, an RF choke in the audio circuit, and then shotgunned the whole audio chain with snap-on ferrites. No more RF on the audio.
  As far as audio quality, everyone says that it sounds very much like my DX60, with the WA1QIX mods, which is pretty much what I expected, since both rigs have a wide frequency response, and I'm using the same audio chain.
  Finally, it's not a "full legal" transmitter. I'm not accusing Bruce of false advertising, but as it comes out of the box it will not output 1500 watts PEP. What I found is that, if the carrier is adjusted to much over 300 watts, the modulation percentage rolls back to around 80%, both negative and positive, no matter how much audio you put into it. At 300 watts of carrier, I can get a nicely symmetrical 100%, but above that, the internal limiter kicks in. Bruce is very forthcoming if you ask him for advice, and he told me that he does indeed set that limiter for around 1300 watts PEP, and that there's a pot, which is shown on the schematic, to adjust that. He seems to be very conservative in his design approach; making the valid assumption that many operators will be using the rig without an effective hard limiter. In my case, with the Inovonics 223, I'm confident that I could tweak the pot a bit and give myself a bit more headroom, but I see little justification for the risk. If I were sitting on a big pile of FQPF11N40's, maybe, but really, for an extra smidge of RF that no one would notice, why bother?
    Overall, a very nice little summertime rig, or a backup rig for your big iron. No buyer's remorse here, at least not yet anyway; time will tell about the reliability.

Transformer found.
Thanks,
Tom N5AMA

He has a very good channel. I’ve learned a lot from him
