lab599 Discovery TX-500 review in September issue of TSM

I’ve gotten a number of inquiries regarding my lab599 TX-500 review. It is featured in the current (October 2020) issue of The Spectrum Monitor magazine:

As you can see from the cover, there are a number of fascinating articles in this issue (click here for a list of all topics in this issue).

You can purchase current individual TSM issues for $3, or buy an entire 2020 subscription for $24 US.

As I’ve said in the past (and despite the fact they publish my features–!) TSM is one of the best values in our radio world. Truly superb articles spanning the full spectrum of radio!

FYI: I understand that Ham Radio Outlet will have the TX-500 in stock within days.

    Thanks for your information about the article in TSM.
    But why on earth do I have to give my private data to spend $3 on one issue?
    Even after I went through this hassle and tried to pay with my CC (actually a debit card for international orders) I get an error message stating ‘The billing address provided does not match the billing address of the cardholder.’.
    I use this debit card all over the world and never had any problem. Well, there are definitely more interesting things to do than searching for the cause of this error and contacting TSM.
    I thought I’ll let you know. Keep up your interesting articles.

      Hi, Stephan,

      This is a nuance of the credit card processing service TSM uses, I’m willing to bet.

      Here in the States, our credit card security protocols are often based on the card number matching the card billing address. Some sites only require the zip/postal code to match. I honestly don’t know what it’s like now, but the US used to be behind the rest of the world in terms of credit/debit card security. We only moved to implement chip readers in the past 2-3 years!

      I would contact TSM, though. I’m sure they can sort things out for you.

    Hi Tom….thanks for a in-depth review….

    I have a question: you mention that you “could add an external voice memory keyer” for SSB field ops.

    Quick searches didn’t give me insight to one….well, except for one from microHAM)…..can you direct me one or two such devices?
