Hi, Stutter - select AF Gain in the ribbon bar and increase the Queue Size. Simon Brown, HB9DRV http://sdr-radio.com From: digitalradio@yahoogroups.com [mailto:digitalra...@yahoogroups.com] On Behalf Of Gmail - Kevin, Natalia, Stacey & Rochelle Thanks for the info. I have downloaded the software and I am currently listening to ur RX. Good copy, but get a bit of speaker crackle and it stutters at times, but that could be because I'm using WiFi. Would be interesting to see if I could hear myself at any of these remotes, be an interesting test.

Re: [digitalradio] SDR-Radio with DM780 20M Digital Band
G'Day Simon, Thanks for the info. I have downloaded the software and I am currently listening to ur RX. Good copy, but get a bit of speaker crackle and it stutters at times, but that could be because I'm using WiFi. Would be interesting to see if I could hear myself at any of these remotes, be an interesting test. I still would like to build a SDR RX, I did see a couple of websites awhile ago, will have to search them out again.

Their is a pin in the unit that needs to be moved if you haven't so that it will send the correct responses for an HT and a mobile/base. Second, check your AXDELAY and TXDELAY's. You might have to readjust those to compensate for the differences in timing issues between the HT and the mobile/base. Third, do you have the proper cable for the Kenwood. Last I remember, there was a difference in the placement and values of the resistors and capacitors used between the kenwood version and the ICOM/YAESU/ALINCO/Radio Shack cables. If this doesn't work, try setting your squelch to open and setting the command in the KPC-3 so that it is software controlled for recieve and transmit. If you have any more troubles, let me know. I have the manual for the KPC-3 here and can probably walk you through the different commands and settings. James W8ISS
[digitalradio] packet not listening fast enough?
Can someone tell me if this makes sense -- I had a RS 2m HT with a KPC-3 and was able to reasonably connect to 3 different stations. I switched out the radio and put in a Kenwood TR 2600 HT. It is lower power (2.5 vs. 5 watts), but those stations still seem to be able to hear me, and I can still connect to two of them without issue. However, the third one when I connect to it sends me a message back that I am connected to it, but my KPC-3 does not recognize the connection and eventually times out retries. Listening to it, the difference that I hear is that station seems to respond very quickly. I am wondering if something is getting cut off, or I need to adjust something int he KPC-3 to tell it to start listening sooner or stop transmitting as long...? Any ideas?
[digitalradio] squelch issue
I know this is not digital specific, but I am hoping someone can point me in the right direction - I have a Kenwood TR-2550A mobile radio I purchased used that I am using for APRS. It worked well at first, but I think it now has an issue with the squelch. It transmits fine and receives fine if I test with my 5w portable HT. However it is not picking up weaker, further away transmissions that I can hear on the HT. The HT is using a rubber duck antenna, the Kenwood has an apprx 3' omni in the attic. The squelch knob did not seem to work when I received the radio, but I was receiving stations, so I didn't care. What do you think I should look at, or can you point me at some places more appropriate to ask this question? Thanks! Scott N1VAN
[digitalradio] Formation of WARC Century Club
Following some interest from members of the 30M Digital Group, we have formed the WCC (WARC Century Club), based on some of the ideas from the Straight Key Century Club . The goal of the WCC is to promote non-contest activity on the 30,17, and 12M WARC bands. This virtual club is for all modes (SSB-phone, CW, and D igital) as permitted by license class and individual country regulations. The group issues WCC numbers and encourages the exchange of numbers with other members during a WARC band QSO. Several awards have been established. Please consider joining this group. An application for a WCC number can be found on the WCC web page at http://www.obriensweb.com/warc-cc.html. A mailing list has been established at http://groups.yahoo.com/group/WARC-CC/ Andy K3UK WCC 002.
