I don't think the old time hams do this kind of stuff. Not sure why, I just think its the less experienced guys. I started a forum once on intentional QRM. No one really understands it because it's inane and stupid.

The reason the DX operator does it is to keep the frequency he is transmitting on clear. He does not need to listen to his own frequency, but everyone else does. If the DX operator gets buried under alot of QRM, no one can work him. Split works better tan everyone piled up on one frequency

My first QSO, the op got me as WB3CX after sending my call correctly twice with a question mark. Have no way to know if he had me right and just made a keying error, I worked him again 10 minutes later. That time he got me as AB3CO, again wrong in the QRM din. I had to do it again 2 hours later to finally get in the log correctly. My guess is that 10-15% of the log entries may be errors. The QRM from people who keep sending their calls after the BS7 op has identified a completely differrent callsign to contact, keeps errors rate is high and the QSO rate down. So wait your turn, find the actual QSX frequency by monitoring the pileup, and your luck will be better.

My next door neighbor experiences some distortion on his FM radio when I operate on SSB, but not CW. This is at high power output levels only on HF bands 20 meters or shorter. His radio has an internal ferrite antenna and no provisions for an external antenna. It probably has no power transformer. In my own home, on a fairly cheap portable FM radio with a whip antenna, my wife cannot hear any interference at all. His radio is a boom box type unit, plastic case, probably not much shielding. I use a low pass filter. I'm making him a power line RF filter, but if this doesnt work, any suggestions?

Just fill out your card with the date and time of the QSO, signal report, band, etc. It saves money if you QSL to a station that you had contacts with on more than one band or mode. That way you can document QSos for single band or mode endorsements of DXCC.

These are some of my new DXCC entities since 11/2006
Asterisk means I used a KW and a beam. The rest were worked on 200 watts and a vertical Cushcraft R7.

I think the point of the post is that rare stuff gets worked every day. The DXpeditions generally have super ops and equipment. Anyone with medium skilla and a useable antenna can work most of the DXpeditions. From the East Coast USA, on a daily basis, 40 meters is open to VK, JA and ZL, KH6 and other interesting pacific DX most mornings, and EU and SA is daily. Lots of Africa 40 meters at 10 PM. Check the DX clusters and keep listening to the weak signals.

I have a HyTower. I run mine with 3 ground rods, one at each leg. I really think you could do it with one ground rod. It is no different in principle than any other 1/4 wave vertical antenna. Six ground rods is not a magic number. A good to great system of radials is the key, attached to the ground rod at the center of the system, as long as possible.

I started this topic, and have thought about it for a while. In the end there are only a few points I can finish up with. I hope that everyone who is a DXer or a good Ham knows that having an argument with another operator on the frequency of a weak DX station is plain wrong, even if you think you are right. Calling someone a LID or an idiot on frequency is adding to QRM so you are no worse than the person you are accusing. Secondly, you will never convince the person who is misbehaving to stop by insulting them. Finally, all those people who are not split, or asking who the DX station is on frequency should get on the internet and check the DX cluster before asking a silly question. Give the dx operators a chance. If you dont get them today, you will sometime before they go home. Please listen to the gentle reminder " UP!" and split. Listening more can sometimes make for more contacts.

I did hear a QRMer on TZ9M on 75 M SSB several nights ago. The QRMer was very sarcastic, making fun of DXers. I'm listening to one of the intentional QRMers on 10.103 now. He is aware that it is annnoying, and laughing at the "Cops" on frequency. The "cops" of course are adding to the QRM. I think the "Cops" should realize that name calling and cursing will only goad the QRM operator into more spectacular misbehavior. They should remain quiet and the QRMer will get bored and go away faster. They love the attention. The motivation to me is still missing, though.  I guess Ham radio has no claim to classy status anymore.

   I am opening a discussion of a very sad and unfortunate topic. That is, intentional QRM by radio amatuers on the frequency of what is important to many hams. In particular, throughout February 9 on both 10.1 and 7.0 mHz, on the frequency of the 3Y0X Peter Island Dx group station, several jammers are transmitting carriers at the same time, causing real copy headaches for those interested in this DX activity. Even more unfortunate is that by the strength of the signals, I judge them to be mostly from USA hams, although I can't be sure. After returning to amatuer radio this year, I was shocked to hear this fairly common practice  which was not prevalent in the 1960's-70's. This is not pileup QRM, this is pure jamming. I'd like to invite comments, hopefully from those who engage in this intentional interference. Why is this being done? Is there not enough bandwidth to give up 10 kc for 2 weeks for a group that travelled around the world at great expense to add to the hobby? Please educate me.
