No support is offered for the AGW Express except for this post. The UZ7HO interface is now supported by Winlink.Ī copy of AGW Express is attached to this post.
UPDATE 8/3/16: W2YG has discontinued support for AGW Express.

Good for a regional or national Emergency network.Ī plus for RFSM-2400 is the chat and beacon mode! The FTP is very usefull for sharing files from one station to another. If ad-hoc networks are the scope, RFSM is the best! You can define a FTP directory and mailboxes for the radio stations and each station can upload emails download their own. Do not try to send big attachements via Winlink! Instead, focus on smaller files, plain text or, if attachements are mandatory, use a good compression software.ģ. There are many iGates on HF and is impossible to miss one, especially if you use the VOACAP tables to estimate the best channel for the given day and hour.Ģ. When e-mail is important, Winlink + Winmor TNC is the one. So, the quick and dirty test have some conlusions:ġ. Using RFSM-2400 the same file took less than 4 minutes. The results were astonishing! Via RMS Express, I sent the file in about 20 minutes. The modulation was set to not activate the ALC. Both were on Wide and the signals on S-meter were peaking S3-S5. The radios were set on 51 MHz, on dummy loads at 5W with a distance of about 1 m between them. I sent a jpeg file in size of 56.0 KB (57,344 bytes or 448.000 bits) with RFSM-2400 and with RMS Express via Winmor TNC. To RMS Trimode and to RFSM-8000 (can act as a server) and a IC-7300 connected to the RFSM-2400 and RMS Express with Winmor TNC. RFSM 2400 can't be used to send files to internet servers but the Winmor is widely used with RMS Express to connect to various iGates around the world to send e-mails.
The speed is bandwith related and is adaptive between 200 Hz and 2000 Hz. Winmor TNC, is a donationware program with a modulation scheme that resembles very close with the one used on PACTOR modems. RFSM-2400 is a freeware client program which can transfer files over a radio channel, using MIL-STD-188-110A standard (300Hz to 3.3 kHz-2400 baud).
Today I did some tests focused on the file transfer speed using two soundcard modems.
