A quick video featuring a WinLink Pactor 3 connection over 2k km (1.5k miles) using Airmail v3. HF mail. Some ALC is present unfortunately. I had forgotten to play with the MIC gain on trcv or FSK/PSK (SCS PTC-IIpro) amplitudes in the Airmail Options menu.

Retrieving messages via telnet - Sally7 PMS vs BPQ32 BBS. Messages forwarding and reverse forwarding. Notes: 1. Send ? and WaitFor password: may not be necessary; Send whateverpassword may be sufficient. 2. BBS Headers List cannot be changed in Unproto. Unproto follows a particular standard headers order. 3. When forwarding, in this setup, the BPQ32 BBS, the BPQ user and PMS have basically the ...

Using DXforward to transfer DX cluster ( DXspider ) sysop messages to an email client inbox. This little tutorial does not apply to node users. After installing the hMail SMTP server and editing the HOSTS file, edit the DXforward as shown. Python and some Windows Bash (GIT) also needed. If, like me, you use this setup on couple of PCs on the LAN, don't forget to open the ports in the Windows fi...

4th take - more spectrum analysis done at the end of the video. I am using a cheap eqp setup. Flat audio rigs should be normally used with VARA FM. But it works even with pre/de-emphasis rigs. Server deviation should be about 1.9kHz in this case. For flat audio rigs, around 2.8-3kHz. Testing some setups involving VARA FM, WinLink, RMS Packet, RigBlaster Pro and M8 and a Baofeng HT; pre-emphasis...

Short video on 9k6 9600 baud packet radio. Some basic packet settings in the AEA PK-96 TNC terminal node controller and and Kenwood TM-D710 and its internal TNC. A short 9600 bd connection, file transfer and unconnected frames are featured. MAXFRAME set to 7, FM deviation on the FT-8800 set to 2.75kHz. 9k6 bd packet requires S9 signals. The TM-D710 suffers of 'deaf VFO B syndrome'. Possibly VFO...
