Hm, thanks for the reply, I did initiate the discussion on the Yahoo group, I was hopeful for an actual user work around. I suppose one could narrow the filter on a potential contact and touch up the receiver. Oh well. Thanks, Rob WA9UAA

I'll take the bait, can somebody tell me how to SPOT a cw signal with the Eagle? I like the TS 590s but could live with some of the differences. e.g. Changing bands quickly isn't a big problem. 73, Rob WA9UAA

Hi Chris, Unfortunately, $200.00 won't get you a lot in used gear from a business. In a private sale you might do better; though, you would want an "Elmer" there to help check out the gear. Many of the guys will tell you the antenna is the heart of the station, it's true. I know this sounds backwards  but work on getting a dipole out there for the bands you named. Higher is better, straighter is better. While you are planning the antenna see if you can get involved with a club, often older club members will part with some used gear at a fair price. Again get a demonstration. The question about the $200.00 rig applies to SSB. If you are willing to learn and work CW the price becomes doable. 73, Rob WA9UAA

Good Day, The mark to space tone difference in Amateur HF RTTY frequencies is 170 Hz to 200 Hz. The difference between the tones for the land line TTY is 400 Hz. (1400 Hz to 1800 Hz) While my AEA PK-232 MBX will copy 400 Hz shift tones, the center frequency of the filtering is at 2210 Hz. This is well out of the range to easily copy land line TTY. Even the Pk-232 "Wide Shift" RTTY reception is out of range of the 1400 Hz to 1800 Hz shift needed for land line TTY. I know it is not what you wanted to hear. While I don't have the specification for the AEA CP-1, the above information should help one make a valid comparison. 73, Rob WA9UAA

Brandon, Yes to the counterpoise, if above ground, they need to be tuned. On the ground tends to de-tune them but also reduces efficiency. ie. you will need more radials.(on the ground) I'd try a counterpoise for each band ie 80, 40, and 20 meters. The 66 foot recommended is 1/4 wave on 80M, 1/4 on 40M is 33 ft. On 20M well you know....These should help get the current lobe out to the radiator. Some folks have had good luck with the MFJ Artificial Ground device, though I'd use it with the counterpoises too. Run the counterpoise wires away from the dipole as much as possible. The antenna radiating field will be working between these two, having the two sets of wires going into the same area can cause some canceling in your radiated signal. Keep us posted.] 73, Rob WA9UAA

Hi Bill, Pay special attention to the instructions as it is possible to do the wrong thing and have to send the rig in to Ten-Tec. That said, I did mine at home and did the firmware upgrade for the CW personality as well. I ran with a WIN XP machine. I'd call the factory about working with a MAC. HTH 73, Rob WA9UAA

Welcome, the short answer is yes, you will be able to enhance the received signals simply by tuning the knobs for maximum signal strength as judged by ear. Depending upon the model, set the in and out capacitors at mid range. Adjust the inductor for maximum noise/ signal and follow up doing the same for each capacitor. Consider getting a tuner big enough for transmitting, the bigger they are the better the job they do on both functions. 73, Rob WA9UAA

I'll give you a quick answer. For the wire to be straight, the tension must be infinite.  It's a better idea to think of reducing tension on the wire when the tree moves. 73, Rob WA9UAA
