I purchased the product just for VHF packet. Thank you Tigertronics for GREAT products for ham radio! I will never 'knock' another company's products but I simply do not understand why anyone would use anything else! The SignaLink is the epitome of 'user friendly', is very competitively priced and is backed by a company with a stellar reputation.

IF I ever did have a problem, I have no doubt Tigertronics would promptly 'make it right'.

I suppose it is possible for a 'bad' unit to get shipped, but again, having owned and operated nearly a dozen units (over the years), I would think that, somewhere along the way, I would have experienced, at least, a 'similar' issue. I see that some users have reported 'issues' and I simply do not understand it. I find it hard to beat having TX, RX and 'Delay' controls 'always' at your fingertips no menus! I have tried various other, stand alone, interfaces as well and have never found one that performs as well as the SignaLink. I have used 'built in' sound cards in various rigs and, although they do 'work', I find that they do not perform as well as a SignaLink and are not nearly as 'user friendly'. The quality control is beyond reproach and the ease of use is beyond comparison. I have used them in fixed station, mobile, portable, battery and solar powered operations with 0, as in ZERO, problems. During ALL that time and with ALL the SignaLink units I have used, I have never had a single problem, issue or 'glitch' with any of the them at ANY time. I am VERY active on the digital modes, including but not limited to, PSK, Olivia, Contestia, et al Packet, VARA, VARA FM, yadda yadda yadda. The reason for the seven units is the topic for another discussion but, suffice it to say, I am trying to 'cut back'! I currently own 7 of them (count 'em SEVEN!). I have been using the Tigertronics SignaLink units for at least the past 15 years, beginning with the models SL-1 and SL-1+ and currently use SignaLink USB units. In any case, over the past, approximately, 20 years I have used a plethora of interfaces with mixed success, including 'homebrewed'. I have been working the 'digital' modes (please, let's not start the CW is/is not a digital mode nonsense!) since the Commodore 64 days, mainly RTTY, before AMTOR was even a 'twinkle in the eye' of its originator. Most of that time, particularly early on, I have worked primarily CW. I have been a ham for over 61 years and have been very active the entire time, including when I was deployed overseas. Not sure why there is more than one place to post a review for the SignaLink USB, but here is a 'reprint' from the 'other post' :
