T7F: Unterschied zwischen den Versionen

Version vom 5. Januar 2009, 19:07 Uhr

The T7F has been built by DF2FQ and is one in a series of fast 70cm data transmitters which have hit the market end of the 1990s. I decided to purchase it on Ebay when I understood that using my TS-790A as a packet radio station is like shooting birds with cannonballs.

Actually, I have two of them:

• I bought my first T7F somewhen end of 2007. It didn't have the optional control interface in front and was nothing but the transceiver board. There's OM Erich Linsmeier DL2RCG, who has developed an advanced GUI frontend kit, which I intend to build up and thus get it running. But that's still not yet implemented.
• Almost a year later, end of 2008, I bought another T7F, this time with the LCD display in front. Since it came only with the display PCB and in all other terms "naked", I decided to build a nice case for it. There are some pictures below that illustrate the building phases.

To the developer's web site:

Here's the scenario in which the T7Fs will be used:

• Setting up a 70cm AX25 based IP link

Here are some pictures with the T7F in a new case. The actual transceiver resides in the silver box. On the photographs you see the T7F user interface in the foreground.

And here's the entire scenery, connected to a TNC2H and a ASUS WL-500GP
