Below is my score from the RDXC contest after my bad calls, bad exchanges and not in the log penalties my final score was a BIG "0" !!!!!! Now that is a humbling experience, I had limited time in the contest and only made 24 QSO's. One would think what could go wrong with 24 contacts.....below is the answer.
VE3WDM claimed and confirmed results in RDXC-2010:
Entry : SOAB-CW-LP

Other missed QSOs (no penalty) = 7
Unical calls = 0
Was my cat Oliver in this contest while I went for breaks.....out of 24 contacts I rolled out 15 total mistakes oh then there were the missed QSO's but no penalty there.

The good news is it can only get better and I sure hope it does. I will say I do like getting these score break downs as it lets me know how I did and were things went wrong.....in the case of this contest I did not do well and just about everywhere things went wrong were they could go wrong.

Elecraft K3 diversity mode
True stereo diversity mode |
Make sure you use stereo headphones the left channel is my vertical antenna and the right channel is my dipole antenna.
Both these recordings were done on 40 meter at 7.030 the filter being used was an 8 pole inrad 400hz.
Do let me know what you think???

RFI issues any ideas....
As I mentioned in a previous post I had some QRN and now think it is some type of RFI. Here is what I have done up to this point.
1.The RFI is on all bands at the same S unit and it is across the whole band just not a segment. I could view this with my PowerSDR software. The whole noise floor would rise and fall in sync with the RFI pattern.
2.When I connected to the Dummy load the RFI was no longer present.
3.With the center pin of the PL-259 only connected to rig RFI was present on all bands again.
4.With PL-259 disconnected from radio RFI was gone.
Below is a recording I did not 20 meters the other day have a listen your feed back would greatly help. I hope to by the end of the weekend know what and were the RFI is and hopefully solve it.

Honey do list vs contesting
I don't know about others but for me when contest day approaches there are voices calling me to do work around the house (honey do list) then there are the contest voices calling out for me. Then the inner compromise is made settling the unconscious verbal war...."Mike you need to have some down time...some rest and relaxation to recharge the batteries." This past weekend was the ARCI QRP during this contest I realized
-I have to recheck the S meter calibration again on my K-3.
-The options for the volume balance during diversity mode with the K- have to be looked into.
-My extra keyboard and mouse I use with my laptop have to be relocated so I will not confuse them with the main PC's keyboard and mouse during the contest.
-The external sound card (E MU 0202) I use for PowerSDR software has some kind of cabling problem.
-Speaking of PowerSDR I upgraded the software and now realize a new calibration between it and my K3 has to be done.
- Finally there is some type of new QRM that showed up during the contest that I have to hunt down around the house.
At the end of the contest it seems my to do list has gotten longer.......those darn contest voices deceived me....hmmmmmmm

Stop dipping my toes in the water
When it comes to CW contesting I feel it is now time to stop dipping my toes the water and just jump right in !!! A few years ago I began my journey into CW contesting and to increase my code speed. For me a CW contest was getting on N1MM logger and using the macros for all the reply's during a contest. Now and then I thought I would step out of the comfort zone and dip my toes in the water and not use the macros, I went LIVE!!!!! That was the beginning of the train derailment I would start to send my report at the same time telling myself not to mess up. If I messed up I felt I would throw off the calling stations rhythm not to mention those in line after me in their shacks just rolling their eyes. Then there is the self talk that is spinning around in my head as well " ok Mike it's just a report 5NN and a serial number" "did I send a H or a 5" by this time the serial number is a distant memory. Now self talk moves to panic. My eyes are wondering around the monitor looking at the N1MM screen......"the serial....where is the serial..." I have now fallen into the state of a deer in headlights. As for my fellow contester's in line after me, I have given them the opportunity to refill their coffee or take a much needed washroom break or maybe BOTH!!!!
Then it's over the report and serial are out there my contact says to them self " thank god" and for me it was like a trip to the dentist. I now just embrace the macros of N1MM and tell myself that the next contest will be different I will give it ago then. This weekend is the ARCI fall QSO party I have not taken part in this contest before and it is my first QRP contest. This will be my first contest were I am jumping in the pool..... no dipping of the toes. I will be using N1MM logger to score and record the contest but no macros. I feel the only way to get this monkey off my back it to get in there and just keep plowing at it. Julie is out and about most of the weekend with photography stuff so it's contest time.

Elecraft KRX3 review
![]() |
KRX3 installed |
Receiving two separate signals on the same band
Click on each image to enlarge |
I wanted to try some simple stuff with the new sub-receiver at first as I had not yet dove into the manual to learn the details of the KRX3. With the two receivers on the same filter (Dual pass band) on the main receiver I found one CW signal in a QSO with another station at 7.013 (in my left ear). Then with sub-receiver I found another station at 7.034 in a QSO (in my right ear). It worked and sounded great I was even able to use different filters and depending on noise conditions at either end of 40 meters use separate NB, NR, ATT, or other filter settings. I recorded an audio sample this is from my 20 meter dipole in the attic. At first you will hear both signals then just the sub receiver (7.034) then both and the the main receiver (7.013). Both of these signals I used the dual bandpass filter.
The audio clips are best if listened to with stereo headphones.
Same band separate QSO's audio sample
This feature is useful in contests when a station I want to work (a multiplier) is involved in a pileup. I can keep them on the sub receiver and work other stations with the main receiver. The sub and main have independent volume controls. The sub-receiver can be lowered and checked in on now and then to see how the pileup is going. When the pile up thins down I am able to hear it and then take the opportunity to work the multiplier.
Working a DX-pedition

DX-pedition audio sample.
Receiving two signals on separate bands
Now because the KRX3 is a totally independent receiver you are able to listen to two separate bands at the same time. The main receiver was on 20 meters and the sub was on 40 meters. (using the same antenna) Again in contesting this can allow me to check another band to see if it is open or closed for action. You also could set the sub for your weekly 80 meter skid. While waiting for it to start make some contacts on 40 with the main receiver. In the audio example you will hear 20 meters on the main VFO then the sub were a station is calling CQ on 40 meters. The audio goes back and forth as well as both bands at the same time.
Two separate band audio sample
Diversity receiving
I consider having two independent receivers to be a great asset, but then there is the ability to listen on one antenna and transmit on another this is called diversity receiving. In my case I have a 20 meter attic dipole and a High Sierra Sidekick outside at the side of my deck. Not a super station but along side the Elecraft K3 it's getting my signal out there. I use the dipole as my receiving antenna as it is horizontal and quiet, the Sidekick is the transmitting antenna. If I was just using the vertical I found I missed out on signals that were close to the noise floor. The dipole was able to pick these up and I was therefore able to work more stations. On Thanksgiving Monday I was giving the diversity mode a workout, at this point I don't understand it well enough to go into any detail. I will dedicate more time to this mode next weekend. I will blog on the diversity mode then I just want to make sure I understand it fully so I can give this mode it's due credit.

How Nifty is that
On Sunday Julie and I were watching the New York Jets and Buffalo Bills playing. We have one of these nice flat screen TVs and Julie thought lets put the TV in sport mode. It makes the greens greener and sound is better and so on. The button pushing started and well no greener greens instead no sound and a picture of snow. Bye bye NFL game and hello NOTHING!!! Now begins the "what the @#$%@& went wrong. There was TV remote button pushing, combination's of remote button pushing, cycling the TV on and off. Then desperation settled in and we thought about looking for the manual.
As hams how many times has this happened to you and your rig? You come into the shack turn the radio on and sometime during the night the radio gremlins paid you a visit. Your sure you left the settings alone but for some reason your memories are not there......or the rig only tunes in megahertz segments, how about the rigs electronic keyer has reversed the dit and dah on the paddle!!!! All you wanted to do was get on the rig for some relaxation and get some QSO's in. You think you remember how to fix things but at the same time your not really sure, heck your a ham so you start to push what you think are the right buttons. Hmmm things are now worse as you have somehow also changed other setting you never intended to. Not only have the radio gremlins paid you a visit but on top of that Murphy has you changing things you never intended to while not getting the original problem fixed, you are proportionately digging your hole deeper as you try to dig your way out!!! At this point crazy thoughts are going through your head like "lets dig out the owners manual".
But wait..... this is were N6FN's Nify Mini Manuals come in very handy! I have there operating guides for my Elecraft radios and have used them many times. Not to put down the owners manuals as they are very useful and have loads of information in them. But there are times you can get bogged down with information while looking through them for a quick fix. This is were the Mini Manuals I find shines, they have a very easy to read table of contents on the front page. Here you find a list of most if not all functions you will want to use. From there you are taken to a page with red lettered headings followed by fast and concise steps guiding you through what has to be done. For example the other day I turned on my K3 and for some reason on 20 meters CW the rig was in CW REV. I tried to be a hero ham and just push some buttons...nothing....grabbed the Mini Manual. Found "CW operation and keyer setup" in the front page table of contents, turned to page 11 skimmed over the bold sub heading" Using CW REV". There I was told to press and hold ALT key.....did that and I was back in business. I have the Mini for my KX1 it is just larger than a business card and it is tri-folded. Easy to pack with your KX1 and again I have used it many times to refer to. N6FN's Mini manuals are laminated for durability this allows them to be brought along for outdoor operation. The spiral binding allows them to lay flat for easy reading. These are a great "Mini" product.

The key issue
The Pelican case was my last post I installed the KX1 in the foam insert and stopped there. During my portable operations I have been using my Bencher BY-1 key. The Elecrafts KXPD-1 portable key just does not work for me, I find I am not able to send dependable code with it. I know there are many out there who use this key with great success but for some reason it just does not click with me. Up to this point the Bencher BY-1 has been the key I use with the KX1. Not really a portable key and with the springs and pivots all exposed I am concerned that sooner or later it will get damaged. So I am on the search for a portable key for my KX1!!! I have done some searches on the net for portable keys. One site I found very helpful was the QRP Amateur Radio Club International website. They have a link to a multitude of Morse code key sites I came up with two that seemed to be mentioned often in portable use and were given good reviews. The first key Im considering is Palm radio's Mini paddles. They are self contained in an aluminum carry case, small in overall size (1x1x3 inches). You can adjust spring tension, contact spacing and paddle stop and they gold plated contacts. All this for 95.00 U.S. The other option is the Bengali traveler light, for those of you who are familiar with the Bengali product line they are very well made and are a high end type of keys. I'm the proud owner of a Bengali Contour Key
I have had it for about 6 months now and yes it was pricey but it is a fantastic key. So I was pleased to see they also offered a travel key. As with the Mini paddle this key also comes standard with gold contacts. It is not as compact as the Mini ( about 1x1x4 inches). This could have me reconsidering my Pelican case size as well. Unlike the Palm paddle which has spring contact adjustment the Bengali uses magnets. Now my contour has magnetic adjustments and it's easy, fast and they stay in adjustment. finally the Traveler has nice weight to it 1.5 LBS. To me this is an advantage as I find lighter keys I am moving them all over the table.But the weighted key, magnetic contacts and the Bengali quality come with a price of 228.00 Euros.
The bottom line is which key......The Mini is smaller but lighter and does have very good reviews. I would have to find a way to secure it to the KX1 so it does not move around. They do offer magnets but the case is aluminum on the KX1. I would appropriate any input on these two keys or any other ideas you may have about a key you may be using.
