1  eHam Forums / DXing / RE: Can I have a QSO with myself? on: May 21, 2013, 10:48:27 AM
I would assume it would be Kosher. Guys on DXpeditions rack up QSOs with their stations while there. 

That's by having someone else operate under their callsign.

These are my two VK6 QSOs from my Washington, DC apartment with a MFJ-1786 magnetic loop.

1.   2012-10-19    09:06   30 m   VK6CR  JT65  -19
2.   2012-10-20    09:23   30 m   VK6IR      JT65  -09
3  eHam Forums / Digital / RE: Too much info on PSK31?? on: March 20, 2013, 09:58:43 AM
This is how I want a PSK31 QSO to go:

CQ CQ CQ DE N8HM N8HM N8HM PSE K

EA1AB EA1AB

EA1AB 599 EA1AB

TU 599

EA1AB TU 73 QRZ? DE N8HM K

Sadly, I guess I have to resort to RTTY for that kind of QSO.

Would Kenwood th-f6a be good enough for receive? I have IC-7000 for transmit.
Ignacy, NO9E

Yes, with some practice. The SSB filters are very wide. I've done it with the F6 and an 817, and I think Patrick WD9EWK has as well.

I've made one QSO on VO-52 with a TH-F6A and an FT-817. I have to get out and try it more often.

I went back out and attempted to make some contacts on SO-50.  I used two handhelds (FT-60R as my transmitter and FT-470 as my receiver).  I choose passes that were the elevation was equal or greater than 40 degrees.  I had no issues in hearing contacts being made; but, I could not hear myself when transmitting on my receiver.  Could it be that:
1. I need more power?  I am transmitting at 7 watts.
2. I am still not aligned with SO-50?

Thanks.

You may also be experiencing desense. In order to hear myself on the UHF downlink of SO-50 or FO-29 when using my Arrow, Yaesu FT-817, and Kenwood TH-F6A, I had to connect the output of the Arrow's duplexer to a second duplexer (an MFJ) and then the output of the duplexer to each radio.

No voice systems are active on the ISS at the moment unless the crew is making contacts. You'll want to try working SO-50.

I heard some guys harassing a Chilean station with a CD#### call on 10m SSB a couple of weeks ago. I tried to inform them that the call was valid, but they either didn't hear me or just chose to ignore me.

The direct source for the validity of any Chilean call is right here:

It can be hard to get a word in edgewise sometimes (that's why being able to hear your downlink is helpful, you know if you are getting in to the satellite). Just keep trying. When a QSO is finished, key up and call one of the stations that was just in QSO.

Can you hear the satellite? Are you transmitting a 67.0 Hz tone?
10  eHam Forums / Satellites / RE: Arrow-II 146/437-10WBP : test data on: November 05, 2012, 11:04:37 AM
I can get into VO-52 and AO-7 on their 70cm uplinks fine with the Arrow and 5 watts, so I don't think it's a big problem.

Have you tried FO-29 with that setup?  I did in the past, and had desense when I had the Arrow as my antenna with two FT-817s connected to each of the Arrow's feedpoints.  Even at 5 watts. The FO-29 desense went away when I went to the Elk, and then used a Comet diplexer to feed the single feedline from the antenna to the two radios.  VO-52 and AO-7, along with Fox-1 when it is launched, all use 70cm uplink frequencies which gets you away from desense due to the 3rd harmonic of the 2m uplink transmitter for the current FM bird(s) and FO-29. 

N6JSX mentioned the duplexer design for the Arrow.  It is not very durable, and - of course - only rated for no more than 10W due to the size of its components.  You can improve things with some other duplexer, but most of those will be larger than the one from Arrow Antennas.  Before I switched to the Elk, I replaced the small Arrow duplexer with others (once I used a Diamond duplexer, then an MFJ that looked just like a Diamond duplexer, then one from Comet). 

Good luck, and 73!


Desense problem is solved. I've got the Arrow duplexer in line and then I split the signals out again using an MFJ duplexer. That provides enough isolation to eliminate the desense. Of course, I'm not sure how bad the insertion loss is. I heard SO-50 down to about 10 degrees of elevation today. Of course, I'm in an urban area, so the buildings are always a problem.

Just got an MFJ duplexer last week. The S meter no longer activates on the TH-F6A receiving on 435 MHz when transmitting with the FT-817 on 145 MHz, so that's encouraging, but I haven't had an opportunity to try it on a pass of FO-29 or SO-50 yet.

Still getting used to tuning for Doppler. I've heard myself on the AO-7 downlink and made one QSO on VO-52. I keep getting which way to tune screwed up in my head!

I worked W5XZ on SO-50 on Saturday. He's using a Wouxun. There is a video on YouTube of a guy making QSOs with a Baofeng.

If you operate digital, SV5AZK is on PSK31/PSK63 quite often. I usually hear him between 0200 and 0400 here in Washington, DC.
