2-Way QSO's


First "Part 5" 2-Way QSO in the 137 kHz Band: The first known 2-way QSO between FCC Part 5 licensees in the 135.7 - 137.9 kHz band was accomplished on November 12, 2004 (UTC date) from 0200 to 0227 UTC. The participants were Warren Ziegler, K2ORS/WD2XGJ, and John Andrews, W1TAG/WD2XES. Hand-keyed CW at regular keying speeds was used, with a normal amateur radio CW QSO format. The call signs were WD2XGJ and WD2XES, as "ham" call signs would not be appropriate in this range. The two stations are 25 miles apart. At the time of the QSO, WD2XES was running 200 watts into a 40' X 65' (H X L) vertical loop antenna. WD2XGJ was running 250 watts into a 70' X 150' loop. Receiving equipment was an Icom R75 at WD2XES, and an HP 3586C SLM at WD2XGJ. The contact was recorded by Jay Rusgrove, W1VD, at his QTH in CT. A short MP3 clip gives an idea of how it sounded.

WD2XDW QSO 29 October 2005: See the details here.

WD2XDW QSO 12 December 2005: Laurence and I had a one hour WOLF QSO on 137.577 kHz at the 20 bit/second rate from 0030 to 0130 UTC. We worked in 10 minute segments, and complete copy was received in each segment. We then tried JASON Normal Turbo at 0130. Laurence had reasonable copy of my signal, but a wandering signal from a switching power supply kept disrupting my copy of WD2XDW. So we switched to WOLF at the 40 b/s rate, and had perfect copy in 5 minute segments from 0200 to 0230 UTC.

WD2XDW QSO 24 December 2005: This one was in QRSS3 mode on 137.577 kHz from 0000 to 0110 UTC. I had been sending WD2XES ID's for a half-hour before that, and Laurence was easily copying the signal. We each made four transmissions during the contact, and the only problem was a very complete fade in the middle of Laurence's 0042 UTC transmission. Parts of my signal were copied by Hartmut in Germany, and he had better copy of my ID's later when I went back to beacon operation.

WD2XNS QSO 29 January 2006: Jay and I worked from 1848 to 2017 UTC (71 mile daylight path) on 137.422 kHz. We began with CW, 100 watts on my end, and 50 at his. Copy was easy, with 569 reports both ways. We then switched to WOLF at the 40 b/s rate, and each made three transmissions. Next was JASON Fast Turbo. Jay had a problem with one of my transmissions, due to rain static, but I went up to 300 watts, and all was OK. We then used PSK08 without trouble. Finally, we tried PSK31, but had some software setup confusion. It appears that copy would have been OK, though. We will pick up there the next time.

WD2XNS QSO 25 September 2006: Jay and I started what we hope will be a regular schedule to stimulate listening interest at 137 kHz. This was a CW QSO from 0100 to 0137 UTC on 137.779 (XES) and 137.781 (XNS) kHz.

WD2XNS QSO 04 December 2006: CW QSO on 137.779/781 from 0200 to 0233 UTC. Jay briefly worked WD2XKO in CW mode before our contact, and again after. I could not hear Dex due to local noise until 0235, when I had some copy.

WD2XNS QSO 11 December 2006: CW QSO on 137.779/781 from 0200 to 0240 UTC. WD2XGJ joined at the end. WD2XKO may have called at the end, but we could not copy him. Poor long-haul cndx.
