Hello Topbanders, For the past few months I have been plagued by what I suspected was power line noise on 160 meters, and finally was able to track it down to a power line pole 0.66 miles from my hou
Today I built the ADSL filter today that Rag (LA6FJA) provided the link for, and it solved my DSL crashing problem. I fought this problem for numerous years when running 100 watts on 160 meters and p
I've covered my resistors and solder joints with GE Silicone II sealant I do the same thing with my pennant termination resistors (just cover them with GE Silicone II sealant). 73's Don (wd8dsb) ____
be very sure that if you pick GE silicone sealant.. (RTV or whatever you This is a very good point, and this is the reason I use GE Silicone Sealant II versus GE Silicone Sealant I. GE Silicone Seala
In February of this year I built another ADSL filter originally designed by OZ1CTK, but this time I used off the shelf surface mount components (my original build used through hole components, etc.).
Dean, I purchase the 2.4" O.D. 31 mix cores (Fair-Rite part number 2631803802) from Arrow Electronics, and the single quantity pricing is currently $4.83 per part. Shipping is $8.00, but the low piec
This month a beacon like CW signal appeared on 1.816 Mhz at my location (24 hours a day, 7 days a week), and yesterday with the help of my neighbor I was able to locate the source of the signal which
Digging back through the archives I found lots of discussion about the "best" transformer to use with flags, pennants and beverages. The discussions included material type, and style (toroid vs. bino
I had additional offline conversations with Rick (N6RK), and Carl (KM1H), and below is my official response to my original post about RX antenna transformer windings and complex impedance measured on
I've been using Radio Shack 30 AWG insulated wire (wire wrap wire) to wind my binocular cores for RX antennas. It comes in 50 foot spools, and you can buy it in Blue, Red, or White. This insulated wi
I'm mapping the data, but nothing to hang my hat on at this time. The data from Steve (KK7UV) does not intersect any of the other reports (odd). A heading from W8JI or AA1K would be very helpful. Don
OK, while we are on the topic another very big factor to think about is magnetic north vs. true north (I have tried to not bring this up in the past). I don't expect any response to this, but this ha
Having more time this evening I went to an open field with two different portable DF antenna systems (shielded loop, and terminated flag), and I'm now going to say the signal is 140 degrees from my l
Oops, I compensated for true north backwards on my last report. Therefore I should have said the signal is 130 degrees from my location just NE of Indianapolis (130 degrees True heading which is very
Paul and Gang, Based on Pauls heading and a few other headings that intersect Pauls heading, it looks like the signal is originating from the lower half of NC, or the NE part of SC that touches NC. H
Hi Guys, K5ESW reported the following : The 3501.5 carrier is audible in daylight in Raleigh, NC. It is running What would be interesting to know is if anyone can hear this signal 24 hours a day, and
To follow up on Toms comments about high angle, I have noticed that at my home QTH where I have have 3 pennants (one pointing 40 deg, one pointing 160 degrees, and one pointing 300 deg), that normall
Hi Rick, The beacon that you mention (what I assume I'm hearing around 3.500.9 this morning between 1130 to 1200 UTC) is on a lower frequency (approximately 0.9 Khz lower) than what I was previously
Rick and gang, as a follow up I just contacted Bill (w4hbk) via e-mail, and the QRSS beacon that you mentioned above was definitely not the signal we were tracking last week. Bill said the following
