Re: [IC-7000] I hear audio in the speaker when transmitting
Randy Thomson
In the "old days" this could occur when a tube in the audio output developed
"microphonics." That is, a slight vibration of the tube would vibrate an element inside the tube, causing the mechanical energy to be converted to electrical energy. In solid state electronics, that's more rare, but still possible. It can sometimes be traced to a marginal connector, a bad solder joint or a cracked board, where the components still make contact, but vibration varies the resistance of the connection.

Subject: [IC-7000] I hear audio in the speaker when transmitting I just purchased a used IC 7000. When I transmit, I hear my voice in the speaker or headphones.

Re: I hear audio in the speaker when transmitting
That isn't a problem I've encountered before, given what you've done to eliminate the usual causes.

One possiblity perhaps is someone has had the case off and some of the grounding spring fingers and pink RF absorbers aren't positioned correctly. There's a document with pictures of how they should look in this Group's Files section. Look for '7K Grounding Fingers.doc'. Just to be safe, I would check the DC supply voltage as seen inside the radio while transmitting into a dummy load at 100 watts in CW or FM mode. Measure across pins 3 & 4 of the TUNER connector. You should have at least 13.0 VDC there, assuming your power supply is set for 13.8 VDC. If you have a high resistance in the power path somewhere that results in several volts drop under dynamic loads, it can cause various problems. Poor shield connections (or slightly loose shells) on the PL-259 connectors can result in a lot of RF leakage right at the back panel, that really mess up the rear mic and speaker cable signals. Lots of luck finding the problem or returning the unit. Steve, W3AHL

Right now am doing a lotI also operated for YEARS using a bug, and finally decided to move up to an electronic keyer, both to get more consistently good code, and to improve my sending speed. I was very concerned about the learning curve, but I went ahead anyway, about 4 years ago. For fun, I built one of the Idiom Press CMOS keyers. Very nice kit, and it went together perfectly the first time. For paddles, I went to the local ham store (HRO) and tried everything they had. Since I had developed a pretty "heavy" fist from years of bug-swiping, I ended up with the dual-paddle Vibroplex. The feel was very much like my old bug, and you could whack it pretty hard without it moving or hurting anything. (In contrast, the popular Bencher paddles are more appropriate for someone with a light fist. My girlfriend uses these, but she learned CW on a paddle, and didn't have my "old dog" problem.) To my surprise, it took me all of ten minutes or so before I was on the air, full iambic/squeeze-key (iambic A), making QSOs. My speed rapidly went up, and I can now comfortably ragchew at 35 wpm or so. I was amazed that the learning curve was virtually non-existent. I can still use a bug, but it's somewhat unnatural now. After a while, I decided to get a better set of paddles. The Vibroplex is OK, but the adjustments are a little rough, and it is a "spring tension" paddle, which means that it will change over time as the springs wear. I ended up with a beautiful hand-made Fratelli Professional. (Similar to the Iambic Chrome at: http://www.i1qod.it/prima.htm, but solid brass, and solid plastic paddles.) This paddle also can take a "heavy" fist; it weighs over 3 pounds, and does NOT MOVE on the desk. It has magnetic tensioning, which is as smooth as silk. Instead of springs, the paddle tension is set by moving a magnet, one for each side. These are the modern "neodymium" magnets, that have incredibly high magnetic strength, and small size. The magnets are set so that they repel each other; by moving them closer, the tension increases (more magnetic repulsion). You can set these to very high, or subtly low tension, as you prefer. They never wear from motion, since the tension is magnetic, not mechanical. Rich KE1B

I'm 70 and am interested in the same things as you. I am learning oncemore CW, but slowly and with some audio problem ( my ears went injured by explosions and working near by big turbines ); I have never practiced long enough to have hold a reasonable speed, but they told me I have a good fist. If you get these informations you asked for by private mail, please pass them to me, too. Thanks, and maybe some day we will be able to meet on CW 73 de Augusto i2jjr / hb9tza

Re: [IC-7000] Iambic paddles
whitegrouch
Hello Jim,
I use a Vibroplex Vibrokeyer with the conventional dot-dash paddles like a conventional bug, not Iambic. I use one in the mobile with my IC7000 and the second in the shack with my TS850. I bought an iambic paddle with the 850 back in 1994 and within days reverted to the single paddle vibrokeyer with great success. I am halfway to my 77th birthday and have been a brass pounder since 1950, and as my straight key prowess gets sloppier, I find that I can hold my own at 25WPM with the above keying combos in the mobile and the base. However, to each his own, and I hope that you find what is right for a youngster as yourself... 73, Joe 4Z1JW / W2FJF On Sun, Jan 27, 2013 at 6:12 PM, James Brock <jbrock@...> wrote: ** -- Joe Weisberger SEMPER FI [Non-text portions of this message have been removed]

Hi Grant - we have spoken on the Blenheim repeater
toggle quoted messageShow quoted text
My IC7000 smoked when it was about 10 days old, and was definitely in receive when it did, and I was at the other desk and only alerted by the smell Fortunately I'm only 30 minutes from the local HRO store where I bought it, and to their credit they replaced it on the spot HRO told me that the vast majority do not fail, but of course the statistics on this group are biased because only the owners of failed units post Its now remote controlled at my ZL QTH, so it had better not smoke again, otherwise the alarm monitoring company and fire brigade will be my feedback loop! Overall, I'm very happy with the IC7000, its ideal as a remote control rig due to its HF/VHF/UHF capability, and I think it will be great for my intended future use as a mobile rig The only issue with remote control on the IC7000 that people need to be aware of is HF RF getting into the USB to CI-V interface. I fixed this with good shack grounding, grounding the USB through using a very short (6 inch) USB extension cable between the laptop an the USB-CI-V adapter, with a ground wire soldered to its cable shield, and putting a ferrite on the cable to the rig. Fortunately, the IC7000 stops transmitting when it loses CI-V communication. My CI-V interface is a West Mountain Radio "RigTalk", but I had exactly the same with a generic (Chinese) version. The Icom one is much more expensive, but may of course be better Roger NZ6RQ / ZL2BHW
