Worked best when the TX remained keyed (2 back the back GE Phoenixes with an inverter and buffer between disc and mod) - Jim suggested a delay line. If the...
Well today I got on 2m D*Star with W4ART (IC2820) FT Ward Park, N8YSZ (IC2200h) Arlington, KI4GHW (IC91AD) 7 Corners and K4MDD (ID800) 7 Corners. I had the...
Hello Dan, It would be interesting to compare with an analog repeater on the same antenna, duplexer and line and do an a/b comparison. My guess is that ...
John, KH6MEI uses an Icom 91AD with a Mirage BD35 dual band amplifier. I did not notice any loss of data on the preamble, but there was a little garble on his...
I just upgraded from 800 to 2820s at the house and in the car. I have noticed that the 2820 seems to receive better, regards of diversity. I have especially...
Hello, we're going to be demonstrating D-STAR at the Orange County Fair, in Southern California. We will be using the K6SOA 2m D-STAR repeater so listen for...
Having mixed results with uploads/download throughput via a local Linux server at our D-Star repeater, I was curious if I should try changing some of the...
... Same as any systems engineer does. Establish a baseline, then see if the deployed system can meet the baseline. You've just asked if you should change six...
In reference to your last question Mel... Concerning 1.2 GHz operation for D-Star and FAA Radars. The Temple Texas area has an FAA Radar Site located nearby--...
I am giving very serious thought to installing a 23 centimeter data repeater and buying an ID1. I suspect the repeaters are pretty much alike, and so are the...
We will be installing a Comet GP21 which is about as high gain an omni vertical as you can get (or so I have found.) Its a bit antenna and we have used them in...

Greg Saratt W4OZK put together a very concise and brief presentation on setting up D-Star Radios to get on the air (GOTA) quickly. This file is on the Alabama...
I have been mulling the Comet GP21 in the $150 price range and the Hustler HS12-12430 in the $500 + price range..... The antenna that I buy will go on a 175 ft...
Steve, When it comes to repeater antennas one gets what one pays for. The Comets are simple thin wall fiber glass sleve with usually #12 wire with components...
Gordon, It looked as a protocall or procedure for using your multi-repeater system. I guess I was expecting details as to what D-Star is. Am I missing...
Hi Ron: Your right, the page is meant to help you get the radio setup when you get it out of the box. The reason I started the page I was finding that when...
We use several of the 12db gain Hustler Spirit antennas in Alabama. They are very rugged and look to last much longer than the amateur grade. we are looking...

Thus far Comet and Hustler have been mentioned. I am inclined to spend a little more for a higher quality antenna. There is also a possibility of 23 CM DV as...
Hi Steve, I have been using a Comet GP21 with 7/8" Heliax on my repeater in Dallas for about five years. The system has performed well and I have had no issues...

Al sounds to me that you have the TX offset in the radio on that certain memory channel set wrong. Thats the only thing that would cause the radio to show OFF...
Has anyone done BER-vs-Eb/N0 curves on D-Star? I see some bit error rate curves as a function of receive signal strength, but the problem with such curves is...
