I asked that question. While I knew the other station was sending RRR based on our previous exchanges, the pattern never was clearly identified with my eye-brain connection, nor decoded by the software until later. I was interested to know whether the decoded RRR message was required, or whether it would be productive to keep straining at the screen, as I had been doing. I strongly endorse the superior sharpness of the spectrum display of WSJT-10 over WSJT-X for this purpose. Thanks for the responses! I will stick with WSJT-10 for this reason. 73 Parker W5ADD

EME condx

by DW Harms PA2DW

Hi all, As it is holiday season, I did not mind to do some nightly EME activity on 23cm last two nights. Most enjoyable! I worked only one CW station (VE6TA, tnx Grant) but 4 new inits on JT. Ik1FJI (excellent signal, we can try CW!), W2HRO, W1PV and K5DN. That motivates me to try again coming night, so I hope to meet some new ones again and also old friends of course. And hopefully on CW, however I run on one leg as one of my modules is still broken so 250 instead of 500W If I dont meet you tonight, I take the opportunity here to wish a healthy and prosperous 2018! 73, Dick PA2DW Rig: K3 and Kühne TR1296H (GPS locked), SSPA 250W, LNA 0,16 dB, 2.4m prime focus dish, OK1DFC septumfeed with choke.

Question about Wilkinson combiner/splitter

by IZ2EWV Italian amateur radio station

Hello, I'm building two Wilkinson combiners/splitters for coupling two 432 MHz 500 W SSPAs. I'm using coaxial cable contrstruction, but I should like to be very sure about cutting the 70.7 Ohm branches, whose length has to be 50*sqrt(2)*VF. In my logic this length should be measured between the two ends where the jacket is cutted and the shield is plied away from the dielectric (after the cutting of the jacket Z us supposed to change...): is it correct? My doubt arises from a manual of RF engineering where I saw a picture in which the dimension line of the branch was drawn between the ends of the central conductors... I would like to avoid trials because I have not much quantity of 70.7 Ohm coaxial cable. So I ask you all, hoping that somebody experienced this construction. Tnx es 73 de Alberto, IZ2EWV

Hello everyone

by HorieToshimi

Hi EMEer In the past few days, Darg's value is low but the path from Asia to other areas seems not to be good. I am QRV yesterday, the day before yesterday and the day before 1200 Z to the 70 cm band, but I can not trace the signal of Europe. However, I am in winter vacation now, Therefore I will QRV every day for a while. Everyone in the world, please QSO by all means. de JE2UFF Toshi PM94bu

Short Hand Messages in JT65 EME

by Curt Nixon

HNY List! I saw something during operation on 2M last night that made me re-think my understanding of the practical use of JT65 for EME. A station was having some difficulting completing a QSO and the other station had been sending SH RRR for many cycles. WHen finally complete, the station having the Rx issue indicated they knew the other was sending RRR because he could see it, but never switched to 73 because they never got an RRR Decode. This puzzled me because my understanding of the use of the special coding for the RO, RRR, and 73 Shorthands was designed so that they would be easy to visually verify. My standard practice has been that if I am able to "see" the RRR at the correct location, I will consider it received and progress to 73 regardless of a missing software decode. Am I operating outside the accepted bounds of standard practice by doing this? Happy New Year to all on the list. Curt Nixon KU8L EN82 Vizkey

Re: [Moon-Net] WSJT-X and TS-2000X

by Edward R Cole

Paul, Glad you found the solution. As hams we long have used grounding to control probably dating back to the old vacuum tube days of high voltage CW keying where you grounded a grid bias. But the digital ckt engineers (that probably do not have the ham experience) use digital HI levels to activate ckts. I suspect that is what you found. Most ham sw use either RTS or DTR lines from RS232 ports to key a radio. My old HB digital interface ckts used a small NPN transistor (eg 2N2222) to key the radio PTT line or key the CW KEY input. A HI to the transistor pulled the radio control lines low. Apparently the TS2000X was designed for direct RS232 interface. 73, Ed - KL7UW At 05:45 AM 12/29/2017, Paul Andrews via Moon-net wrote: >Hello EME'ers, > >I solved the WSJT-X (for Windows) to TS-2000X problem using a free >software tool called "dxlabsuite-commander". > >Dxlabsuite for Windows told me that the TS2000X (sometimes) wants to >see the RS-232 (CAT) RTS (Ready To Send) line pulled HIGH.

WSJT-X and TS-2000X

by Paul Andrews

Hello EME'ers, I'm looking for someone who is successfully using WSJT-X v1.8 and the Kenwood TS-2000X. My interest is TS-2000X freq control for doppler compensation on 23cm. I have tried WSJT-X for OSX and WSJT-X for Win10. The USB to RS-232 (CAT) cable uses the Prolific chipset. I am seeing communications instability that eventually causes WSJT-X to lock up and require a full power down reboot. WSJT-X is bulletproof until I try to control the TS-2000X. I'm using WSJT-X with the TS-590S and not seeing these problems. Help and / or suggestions will be greatly appreciated. HNY - 73 - Paul - W2HRO
