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 a number of them:
- I bought my first T7F somewhen end of 2007. It was really broken. A friend put it into the garbage bin. So it was not only broken but also lost.
- 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.
- The third T7F also came naked. I also decided to build a case, this time using Erich Linsmeier's interface. OM Erich Linsmeier DL2RCG
- And my fourth T7F also came naked. I am still unsure what I'm going to do with it. Probably it will be a mobile TRX for the low speed data link.
- And yes, I got a fifth one. Naked. Previous owner DL6QS. Will be the last one I am buying.
To the developer's web site (Holger Eckhardt, DF2FQ):
Here's the scenario in which the T7Fs will be used:
And here's some more information about a T7F construction project:
1 The T7F with the original GUI from Holger DF2FQ
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
2 The T7F with Erich's GUI
Erich's GUI came as a kit. It is an ATMEL based controller which is visible on the below images.
