IC-R75 w/DSP and power brick
Yaesu FT450D w/Samlex 1223
Grundig Satellit 750
I mention these here in case someone comes looking to make certain y'all know its legit. I have them listed on QTH and Facebook ( well, the Grundig isn't on QTH as of this writing but I'll get there )
I now have multiple Lampkin 109s. As expected, I can make some cards for these that will make'em a bit more useful and am working on this idea a bit. Hardest thing is how to access additional features without modifying the front panel.
In other news, I finally have an antenna up at my QTH. 31' wire in a vertical using a Jackite pole. SG237 Smartuner and a few multiband radials on the ground. Ain't much but only required a little bit of hammering to get it installed. Yay me!
73,Just figured I'd update. Tested the TARGETuner with the TS2000 and it works great. No other updates at the moment. After using my Truck as a test rig I now need to go out and clean up wiring again so I can go operate a bit...
Go buy one! : West Mountain Radio TARGETuner
73,California realestate just got too expensive for me and I needed a change of scenery anyway.
Got a TargeTuner box from West Mountain Radio. They have since updated the Firmware to support the Kenwood TS480 and send me an interface box to test, which I can confirm works perfectly. I need to test it with the TS2000 and then return it to them as its a factory sample. Anyhow, if you need a Screwdriver Controller for Icom, Yaesu, and very soon Kenwood and you don't want to have questions about how they sourced their IP and the like ( see my Feb 2014 post ) now you have an option.
As a side note, I'd love to hear that the TurboTuner2 was handed off from N2VZ and not just a clone that was similarly named and shaped. If it was a From Scratch device thats cool too, but from the look I have to assume that its intentionally a very close clone that is intended to be confusingly similar to the original. I'm sure it works and feel free to buy it, I just have issues.
So, time for another pet peeve of mine. Everyone has equipment they love. Sometimes it was purchased at full retail and sometimes not. When you go to sell a piece of gear, keep in mind that what its worth probably has no relation to what you paid for it.
So, I've decided the net needs more info about the Lampkin 109 Communications service monitor and whatever other Lampkin gear I can find details for. I haven't scanned the full manual yet. I really don't want to see it show up for sale on Ebay... If you happen to be in need of the manual, email me and see if I've gotten around to it.

Yeah, been slacking.
Gear is finally all mounted in the truck. TS480HX and TM-D710. Dual band VHF antenna ( 2M/440 ), 6M FM antenna, Screwdriver for HF. I still need a Kenwood Screwdriver Controller. I'd buy the one from N2VZ but he seems to be out of business. The only other viable option is the Turbo Tuner 2 from TennaTronix but it looks like a straight clone of the N2VZ design with no credit given so they won't be getting my money. The solution for the moment is using an Ameritron SDC-102 while I build my own automatic tuner which will be open-source open-hardware. Yee-Haw.
I'd love to find out that the TennaTronix box was either licensed or a fresh design but seriously its the same box and everything so I can't help but think at least they wanted it to be mistaken for the original? If its legit why not just say so? Email responses were vague or non-existent. Sad.
Next up for fun is hacking on my TS2000. Going to replace the ceramic filters with Murata ones ( you can buy them from Mouser, don't get the generics from Taiwan that you can buy from that UK outfit on Ebay. I don't get why companies get all furtive when you want to know where a part is from. Anyway, the proper Murata ones are standard parts from Mouser for a few bucks each. I also ordered some PIN diodes to do a minor upgrade and a Z10000B buffer amp to add a first IF output to use to feed a bandscope. Looks fully possible to use RTL-SDR as a cheap Panadapter which would be kinda sexy...
73,Not many updates in the last year and a half. New job, other projects, lack of time.
Prepping for Field Day 2013 right now. Just purchased a TS2000X to use for the VHF station that I normally run. I dont have much else to prep for this year except coming up with an upper bearing for the antenna mast so I can run out some guy wires this time. Should make it easier to erect too and I'll have less heart failure during the tilt-up/down portions of the day.
On the mobile front, I bought a full size Ford truck to put all my gear in, then let it sit for a while due to some noises it was making. I'm now working on the truck and planning to mount all my gear and antennas in it. As part of that I'm on the hunt for a TS-480HX to put in it to replace the IC7000. Nothing really wrong with the IC7000, I just don't like the interface. I sorta seem to be going All Kenwood. Well, I'm going to keep my IC706mkIIg for the moment but good shance I'll sell it off too.
Hopefully soon I'll actually do some operating again...
73,I dragged my Alinco DJ-X11 out again to play with a new project and for some reason decided it was a good time to update the firmware. Simple I thought since I had purchased a cheap clone of the ERW-7 programming cable.
The Firmware update software, the cloning software, and the remote software all seem to have been written by the lowest bidder. And they were drunk at the time. And possibly suffered from massive head trauma. In any case, do not expect to enjoy using any of them. They *do* work to some extent I suppose. I will say I was unable to get them to work under Windows 7. I had to resort to a Windows XP box to make anything work reliably. Even then using the ERW-7 I bricked the unit on my first update run and had to do the restore, which worked after a while although was very slow. I would suggest perhaps lowering the transfer speed as suggested by the instructions for the firmware software.
While doing battle with the software I thought I had a bad cable, so I dug around on the net for information about them. I couldn't find much directly but I did determine a few bits of info that may be helpful. The ERW-7 is apparently wired the same as the Icom OPC-478. And furthermore the OPC-478 is the same as an CI-V interface cable if you swap the tip and center conductor or if your CI-V cable has just a mono plug you just have to wire up an adapter to connect Sleeve toegether and connect the CI-V Tip to the new plug's Ring ( tip will be disconnected ).
I happened to have an FTDI TTL-232R-3V3-WE cable ( available from the usual suspects like Mouser and Digikey ) so I wired it up to a 3.5mm stereo connector I had around. Black wire to the sleeve, orange+yellow to ring. It still didn't work under Windows 7, but it *did* work under Windows XP.
At this point I had an upgraded radio and a working ERW-7 ( actually two ) so I decided to see about making an ERW-8. I found some information on this page http://gm.stackunderflow.com/blog/pivot/entry.php?id=161 which got me started. I took apart my charging cradle to confirm its wiring per the page, then cut the mini-usb plug off a cable and wired it to the above mentioned TTL-232R-3V3-WE. Low and behold it worked with the remote software and cloning software just as poorly as before.
Assuming you cut your USB cable open and it has the standard red/black/white/green wires:
| USB Cable | Description | TTL-232R |
| Green | Data | Orange+Yellow |
| Black | Ground | Black |
| Red | VCC (+5vdc) | Red |
White is not connected
So, why? Well, you can get the TTL232 cable for about $15 easily and a miniusb cable for a couple bucks, and make the ERW-8 cable which costs about $45 and no one ever seems to have. If you wanted to get tricky you could make up some adapter cables and replace the ERW-7 and ERW-8 with a single TTL-232 cable. If you already own an ERW-8 and bricked your DJ-X11 during a firmware update you could also just make an adapter cable using a 3.5mm stereo plug and a mini-usb female from a mini-usb extension and a little soldering.
Enough ramblings for tonight. I figured at some point someone else might be looking for ERW-7/8 information and want some more resources.
73,Not that anyone actually reads this site, but figured I'd mention I now have a mobile rig set up in my car and I'm quite excited.
Icom IC7000, High Sierra HS1800Pro, BetterRF screwdriver controller and tune control, Diamond triband 2m/220/70cm antenna.
Its not perfect yet. SWR tunes up fine on 40, but is rather high on 80. Need to run some good ground straps and see if that makes things happier.
In non-mobile news, I finally finished rebuilding my Kenwood TS930SAT. Power supply main regulator is fully replaced and I replaced the kinda ugly regulators for other voltages in the unit. Just as a note, if you are rebuilding one of these and its a later serial number version, there is a 21v regulator on the board that is not on the replacement. You will have to come up with something to replace that as it powers most of the radio. I used an LM350. I tested the current draw of that section of the radio and its below 1.5amps, but an LM317 would probably be very unhappy there. Anyhow, powers up just nifty now. After testing it I installed the Piexx CPU board which went in and works like a dream. In a few days I should have an antenna to try running at the house too. Very exciting. Michael (VK4AMZ) who designed the new regulator board was very helpful and patient with questions while I determined that the SCRs I used had some quirks. A couple small caps and its nice and stable.
If you actually read this and have any questions or something, you can email me. tom@ this domain will get me.
Gee, I should also mention that I finally got N4YLC's HPSDR to work and receive something after a protracted battle with firmware. What we've learned is VMWares USB support is not insanely fast and the people who wrote the docs I found to follow are friggen Rockstars. While not perfect, they were detailed enough that I was able to muddle through and make it work. Now I'm afraid he might want it back. Really want to play with it once I have an antenna up for 6meters.
Its been a busy couple months since my last update. Lets see what else... FRG7 got backburnered while I repair the HP sweep generator I bought with the theory it'd make things easier to work on. Trimble Thunderbolt frequency reference is working fine. Besides setting up an antenna at home for HF and fixing the high SWR issue in my mobile setup I also have a Yaesu FT757GXII to work on. Not to mention other non-Ham related activities. At least I feel like I'm making progress...
Ah well, enough updates for now esp as I am talking to myself most likely...
And another pass at HRO.
And the shopping list:
I've had way too much experience with SMA connectors. I've installed kazillions of the damn things on hardline. I've never had one fail however N7JAK and I had a discussion and it made me start thinking about it some more and some points he made started to make sense after I swapped antennas and coax for the 8millionth time. I figure I'll settle down after a while but until then I'm going to leave an SMA/BNC adapter on all my radios and swap at that level so I can wear out an easy to replace connector and not the one built in to the radios.
Besides, I really hate putting on SMA connectors.
Gear Acquisition Syndrome has landed. I bought myself a birthday present of a radio.
HRO should be happy.
