Kinda spam, but I thought I would pass this along. Andy. Subject: HA1AH Radioamateur Contest Evaluator Software To: [EMAIL PROTECTED] Dear OM, dear YL, I found your e-mail address on the Internet as contact person of a radioamateur contest organizer team or at least related to a radioamateur contest. Here I would like to inform you that I've developed a Radioamateur Contest Evaluator Software which has the following main features: -receives electronic log files -evaluates them -sends feedback to the sender -does cross checks among the logs -creates special statistics -makes easy sending e-mails to contest participants -provides a handy web interface -.

[digitalradio] RFSM8000 and Yaesu FT857
Greetings to all Is anyone using the FT857 for RFSM8000 I have been trying mine out over the past two days after getting a new Signalink USB interface Big problem with the RX passband - it is not wide enough using the standard filter supplied with the FT857 and consequently too much of the signal is cut off on the low frequency end of the audio Waterfall shows that there is no or very little audio up to about 700 hz making it impossible so far to make a connect even though it will spring up the called station every time Any ideas? I am now looking at an INRAD filter either 2500 or 2900 that would allow the required passband audio Any comments or feedback welcome Regards Les VK2DSG
Re: [digitalradio] RFSM8000 and Yaesu FT857
Les, Are you sure it is the IF passband? If your BFO injection frequency is set correctly, you should be able to pass 300 to maybe 2200 Hz. Otherwise, SSB phone will have no lows. If you have audio transformers in a homebrew interface, make sure they have the necessary frequency response. The best around here seem to be the little green ones from Radio Shack. 73, Skip KH6TY - Original Message - From: Leskep To: Digitalradio Sent: Friday, April 18, 2008 9:08 PM Subject: [digitalradio] RFSM8000 and Yaesu FT857 Greetings to all Is anyone using the FT857 for RFSM8000 I have been trying mine out over the past two days after getting a new Signalink USB interface Big problem with the RX passband - it is not wide enough using the standard filter supplied with the FT857 and consequently too much of the signal is cut off on the low frequency end of the audio Waterfall shows that there is no or very little audio up to about 700 hz making it impossible so far to make a connect even though it will spring up the called station every time Any ideas?

Re: [digitalradio] RFSM8000 and Yaesu FT857
Hello, You should be using the digi port, and there is a specific setting that allows you to center the filter passband around typical digi signals. I find 200 hz up works best for ALE. Since the signal is now centered, I can then even use the DSP bandpass to really tighten up. If you have not centered the signal, or are using USB you will need to turn DSP bandpass off. I don't know how the signalink interfaces, but the 857/897 needs no interface for soundcard/tnc usage and is already decoupled at the digi-port on the back of the radio. Have fun, Alan km4ba
Re: [digitalradio] RFSM8000 and Yaesu FT857
Hi Skip The problem is that I need to pass around 2.4 khz of signal audio and with the stock filter it will not do it - have to look at a wider filter or an IC7000 hihi Regards Les From: kh6ty Sent: Saturday, April 19, 2008 11:40 AM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] RFSM8000 and Yaesu FT857 Les, Are you sure it is the IF passband?

Re: [digitalradio] RFSM8000 and Yaesu FT857
Hi Alan This is using the digi port on the 857 with all dsp functions off but I need 2400 hz of audio passband just to fit the non standard RFSM8000 signal in and just cant get it from stock standard 857 Maybe just put it back in my mobile and consider other options for digital use - at least the FT920 works well on RFSM Regards Les From: Alan Barrow Sent: Saturday, April 19, 2008 1:55 PM To: digitalradio@yahoogroups.com Subject: Re: [digitalradio] RFSM8000 and Yaesu FT857 Hello, You should be using the digi port, and there is a specific setting that allows you to center the filter passband around typical digi signals.
