Very good, but have some quibbles

Time owned: 0 to 3 months

Having made an unsuccessful attempt to buy one of these a year ago--I canceled the order after six weeks of waiting--I made another order through DX Engineering, and got the unit in just under a month.
Pros:
- nicely made unit.
- very easy to set up. The internal socket wiring needed to accommodate a particular transceiver is easy to do, and having only two external cables to hook up is a big plus.
- works well with both Digipan and DM780, and most likely anything else you can think of.
Cons:
- The transmit calibration is pretty far off if you're running the sound card at a sample rate of 11025 Hz; the effect of this is to produce an offset between rx and tx frequencies. Maybe I missed it, but I didn't see anything about this in the instructions. It's easy enough to fix: just switch to a different sample rate. But I shouldn't have had to dig through the comments here to find out about this.
- C'mon, Tigertronics, you need to add some rubber feet to the bottom of the unit. The little bumpy deals you can get at Radio Shack are perfect.
- My understanding is that previous Tigertronics interfaces used a soldered DIP header for configuring the transceiver connections. This unit uses 24-gauge wire plugged directly into a socket. That's OK, but I think a soldered header would be more robust, particularly if you plan to use the unit in a portable/mobile setting.
- As has been mentioned elsewhere in these reviews, the received signal amplitude into the internal sound card is a bit on the low side. I had to use internal jumper J2 to boost the signal amplitude. Hardly a big problem, but I thought I'd mention it.
All in all, I'm quite pleased with the unit and would recommend it to anyone planning to get into the digital modes.
