Mike and All, The reason the tower has been bonded to ground is that the tower supports HF antennas as well. The feed lines, rotor cable, and remote antenna relay control cable would need to be decou
Friends, I have done a few experiments and can see that it is my signal showing on KI0LE, so I have just switched to QRSS60 and am going to send JA JA JA for a bit. I do not have any idea how long pr
Mark and All, The beacon will be turned on shortly. VY1JA is in beacon mode with approximately 100 Watts transmitter output QRSS60 137,574+/- (Note the frequency is NOT in the NA watering hole) The b
Scott, and all Thanks for the plan. I hope to guesstimate, and later measure, the inductance range of the Variometer I built so that I have an idea where the initial settings should be. If I understa
Thanks, Jim and Group. Jim's idea to try wiring the Variometer in parallel and see if I have any indication of better things is the first on my list. I am off to the salt mines. Be back in 10 hours.
Jay, Scott, Steve and All, Thanks for the note. The Variometer is built with two coils in both the stationary and rotory windings. Each of these have a one inch space between the coils to allow for t
Steve, Scott, and All, Last night, I was following a thread of another person and their problems with SWR detection in the presence of a nearby strong LF transmitter. It did not dawn on me until this
Hartmut and Friends, You are correct. I did not expect anyone in EU to see my signal in July. I hope very much that someone will eventually see the signal in EU during the remainder of the experiment
All, VY1JA is in beacon mode with approximately 100 Watts transmitter output QRSS60 137,574+/- (Not in the NA watering hole). The FET is running cool with 26.8 volts and 5.0 Amps input. The beaconing
It looks like Ken's idea with the mic connector will work. Closing the up or down pin moves the frequency .01 kHz. What I need to do to use the connector give the rig a single unbounced short pulse s
Friends, VY1JA beacon is on QRSS60 137,778.45, 100 W TX Output from CP20kw, It will continue on this speed frequency except for scheduled contacts. Thanks to everyone who has sent in captures and rep
Hello again Friends, The single FET amp which Steve lent me has been working fine, but if you remember, during tuning the antenna system would come up with some weird wave shapes. The amp uses an air
Scott and Friends, The ammeter check results are in.... Dead Meter. I went over the antenna connections cleaning and soldering and a small amount of retuning was required. Someone asked how things ar
Jim, Yes, The concern for gradual stepping off the desired space frequency means that frequency will have to be monitored constantly when on the air. Monitoring limits the hardware approach to use in
To All my Friends, Does anyone have a TS450 service manual and know how to explain how to modify or adjust the FSK shift down to10 Hz. on the 450? Ideally, the change should be reversible. To speed c
There is a Yahoo group on the subject. I sent in a membership request last night in an attempt to find out if anyone has used the instrument at LF. I am concerned that the resolution at LF might not
I am starting to see progress but now, every time I get close to resonance, the waveform of the voltage becomes quite distorted. I believe that it was Scott who told me that the way he beat the wavef
