Portable Ops in Comfort

| Working my rolling shack portable station from air-con comfort |
We've had a few RV's over the years, but for some reason I've never thought to operate from inside the RV. I have always tossed a wire over a tree and operated from a picnic table or from my camp chair, as here...
But I thought, "Hey, I have a 12v power supply built-into the RV and the built-in ladder makes a nice solid mount for an antenna mast."

| Now I use a Flagpole Buddy with a 30 foot telescoping mast |
Here's a link to the flagpole buddy... link
Our RV has a Converter / Inverter with a spare 25 amp 12v circuit. I tapped into that and ran a power pole wire to the dinette table.
The camper had a coax outlet to watch a TV outside the camper... that's obnoxious. So I cut the cable TV coax and crimped on a UHF connector, and ran that to the dinette table. I simply attach my coax from outside the camper to cable TV coax adapter to get the antenna connection inside the camper. Wallah, coax through the wall with no drilling. The cable TV coax run from the dinette to the wall outlet is only a couple feet so it's not really impacting the impedance of the coax run to the antenna.
I've tried a couple of antenna's and have settled on my end-fed 44 foot wire fed with a 9:1 balun and some clip on radials. I pull the antenna wire through top end of the telescoping mast with kite string, counter-weighted with a heavy sinker. That keeps the wire taught from the end-fed point up to the top of the mast and out at an angle.

The Elecraft KX3 and Ten-Tec Eagle will both match a bent spoon with their auto-tuners and have no trouble with the end-fed on 40m and above.
For a portable key I use my Palm Radio Single paddle. Either magnetically attached to the steel side of the Eagle or just held with one hand while operating with the KX3.

One thing I find interesting about operating while "camping" (if you call towing a small house to a campground camping) is that I seem to also work a suprising number of other stations that are operating from a campground.
 |
| Note the power and antenna connections under the table |
The KX3 can stay on the dinette and doesn't take much room. Keeping the footprint small and the earbuds in, keeps the XYL happy when operating during an outing.
I worked a number of stations on 40m, 30m, 20m and 10m this weekend. It's always fun to tell a station that you are portable, even if you are essentially operating in your home away from home.
Thats all for now.
Lower your power and raise your expectations

Another day of outdoor op’s

1. WA5OVB Phil's IC 7200 was doing a great job picking up my portable signal I gave Phil 579 report and I was given a 569 with some QSB.

| The Chameleon CHA P antenna setup |
2. KW7D Paul's signal was strong, he was in New Mexico where the weather is much more pleasent than it is going to be up this way. Paul was calling CQ and I was able to catch his attention with my portable signal.
3. K3PR is Joes call and we had a nice long QSO exchanging as much info as we could. At first my signal was in around a 229 but conditions changed and I moved up the scale to 559! Joe and I had a nice QSO about antennas, rigs, WX and just what we were up too.
I did hear a station 4U1A the United Nations in Austria and when I first heard their CQ call they had not been spotted and I was trying to get their attention from my portable setup. I did not have any luck and even less luck after they were spotted and the pileup began.

DF0DW WAG contest
IQ1GE DX calling CQ
DL5HIA WAG contest
DF8AA WAG contest
W2RR NYQSO party
DJ6OZ WAG contest
DL0DA WAG contest
As you can see the WAG contest dominated the bands and it turned out the NYQSO party participants were just not making it over the German WAG contesters. I did not include the signal reports in the above list as it was a contest so the standard 599 was sent. I knew I was no were close to 599 as the German stations asked on more than one occasion for a repeat.
Going about it the hard way…..WHY??
Last evening I finally had some time to get on the PC and check out what fellow ham radio bloggers were up too. For the past month I have been working every day and only having time to “fast read” a post and drop a short comment. While surfing the blog sphere last evening I came across KG3V’s blog, the subject of the blog caught my attention “Updating FTDX-3000 Firmware. Below is a link to what I only could call an “adventure”.
https://kg3v.com/2017/10/14/updating-ftdx-3000-firmware/
In the post Tom does a great job explaining how he went about the firmware upgrade and some issues he ran into. Tom also goes over the enhancements this firmware will forward to his FTDX-3000. It’s fantastic how far we have come in radio, in the past if you wanted the upgrades it meant selling what you had and purchasing the new and improved version. Today’s modern rigs can chat either over the internet or with pre-downloaded thumb drives and magic is worked within the rig to either over come an issue, enhance what is already there or add something new! Having said that I just can’t understand what the issue is with the process of the upgrade. It’s just not ham radio with our Nikon cameras to upgrade the firmware it’s…hold this while pushing that….make sure you don’t do this while doing that….and on and on and on. Resources are used writing the rigs new firmware upgrade, time and money is put into it and it’s to make the product better for the end user. If this is the case why the %&^* not make the process for the end user easy peasy!!
Having said the above and let me preface this with “I am not going to say what I am about to say just because I am a fan of Elecraft but if the shoe fits……” To upgrade my K3 or KX3 Elecraft has provided via their website a program that sits on your desktop, one of it’s functions is for firmware upgrades. The process is as follows:
1. Double click on desktop icon.
2. Click on Firmware tab.
3. Click on “Check versions now”
4. Below you will then see the firmware that is installed in your rig and new firmware that is available for your rig. You then click on “Send all new firmware to K3 or KX3.
Your rig will start to click, there will be “stuff” flashing on the rigs screen, sometimes even clicking noises from the rig and then your rig’s screen returns to normal and your done. I have owned Kenwood, Icom and Yeasu rigs and never has it been this easy and my question is WHY NOT!!! Now having said the above it is true I have not owned one of the above rigs for some time now so do comment if the process has changed…but is sure does not seem it has for the FTDX-3000 model rig!
OK I’m off my soapbox now….:))
It’s been a long, long time.
It has indeed been a long time since I've moved to this new work location. The old work QTH was in Warren, NJ and the new is in Whitehouse Station, NJ. Same job, same company, different campus. I am about 10 miles (more or less) farther west into the interior of New Jersey than I used to be. It adds about another 10 minutes to my commute.
There are two of us in my department. Things were easier in Warren, as we both worked from the same (and only) building on campus. We staggered our lunch breaks so that one of us was always on duty. Here, at the new work QTH, we are split between two buildings, each one of us minding our own store, so to speak. Unless you master bi-location, you can't manage both buildings at the same time with one man.
That led towards a hiatus in lunchtime QRP operations as it just seemed not the greatest idea to spend so much time away from the desk. I know, it's time I'm entitled to (it's only an hour) and I really should get away from the desk to remain fresh in the afternoon.
So I decided to take advantage again, beginning this week.
I went out to the car yesterday and hooked up the KX3 to the Buddistick. I heard a lot of stations on 20 Meters, but got no answers to any of my calls. I know the equipment works, I figured it was just a bit of "rust" on my part. But, boy howdy, was it hot yesterday! It reached into the upper 80s (about 30C) here at lunchtime and since I was parked outside, it was hot like an oven in the car. It was a double negative experience - too hot and skunked on contacts.
Not one to be deterred, my little eye spied on something that I had forgotten. This campus has picnic tables! Many of the employees go out to eat outdoors on the nice days. There are plenty of tables, they are spaced widely enough apart where conversations cannot encroach on one another.
It dawned on me that this would be the perfect place to set up the KX3 and the magloop! Sure, I'd probably get some stares from the other lunchers, and maybe from some of the employees who take advantage of their lunch break to walk the perimeter of the campus - but what they heck? Right? It's not like I haven't been stared at before. It's not like people haven't come up to me to ask, "What is that?" before, so tossing self-consciousness into the wind, I decided to set up at one of the tables today.
I chose a table towards the end of the line of tables, the one with no umbrella. Sure, it would be a little hotter with no shade, but it's less than an hour and besides, there's be no metallic umbrella ribs to possibly interact with the magloop.
Before hunting for a QSO, I decided to call CQ for a bit on both 20 and 17 Meters. I really didn't expect anyone to answer, although there's no reason why anyone wouldn't. I just wanted to conduct a little Reverse Beacon Network experiment.
Experiment done, I went back to 20 Meters and found the "sweet spot" with the loop's tuning capacitor. (I was able to set up in under four minutes, by they way. Almost as fast as setting up the Buddistick on the car.) Tuning the KX3 around, there were a bunch of loud stations. Finally, I came upon GI4DOH, Rich in Northern Ireland. He had a strong signal and a great fist, so I gave him a call. He came back to me on the first shot! He was 559+ here in NJ, and I got a 559 in return.
According to his QRZ page, the loop that Rich is using is a receive only loop. This was not a loop to loop QSO.
After working Rich, I popped on up to 17 Meters. There I heard OE3DXA, Wern in Austria calling CQ. Again, loud signal, great fist, so I gave him a call. Just as with GI4DOH, I gave him a 599+ report but this time I got a 599 in return. Both QSOs were solid with no repeats asked for with regard to info, so I am assuming I was at or near Q5 copy. (Even if the 599 in return wasn't exactly accurate.)
It was time to pack it in, and I was satisfied with the two DX QSOs for the day. With regard to my Reverse Beacon Network experiment, this was where the loop was allowing my signal to be heard:
As for spectators, I did get one guy who stopped to ask, "What is that? And what are you doing?" I explained that it was Amateur Radio and an Amateur Radio antenna. In response, I got the (what seems to be standard) "People still do that?" question.
I went into "pitch" mode and explained that yes, Amateur Radio is alive and well, and that for a lot of people in the Caribbean right now it's the only way they can get word out to their families abroad, that they are OK after the hurricanes.
So it was a successful day, I'm happy and it looks like there might not be rain for the rest of the work week.
