It's a good little radio - you will need to add stuff like a digirig sound module and cables to do digital modes You don't have open access to a software api or web server access to CAT control etc

Our kids are learning CW. It’s about time to get them on the air. Want to upgrade from our ancient ICOM radio. On paper the Lab 599 looks like a good option for our use: pre-teens using straight

I've definitely noticed some subtle timing differences between the tx-500 and my other portable rigs (ft818nd, kx2, and kx3). I can easily switch between the others with no issues. When I use the

There are two iambic modes, A and B. Both radios can be set up for either. Maybe you are used to what your KX2 is set at and the TX500 is set for the other. I have made this mistake myself in the

I have found the keyer on the TX500 a bit difficult to use. I am used to my KX2 with full QSK, ?and realize this is slower to switch between transmissions, but the keyer itself seems a bit laggy and

Ok thanks, I ordered in June and haven't seen a thing.? HRO : (

No it was November 2023. ?Just a little over a month ago. 73

Fairchild Semiconductor FAN7040MX appears to be the same, but also discontinued.

It also looks to be obsolete

Same IC but different manufacturer.

I can confirm that newer TX-500 radios have a different audio amplifier.? This radio has a date sticker that says July 2023. 73, - Trevor, N6TJL

Was that November 2022? tu es 73

Very well possible indeed! I updated, but didn't see a difference to before.

That may very be the case, Thomas. It makes more sense. Thank you for pointing it out. Scott N4AAJ

i think you can find the answers from reading the threads. This is my take. I had a failure on my charge controller, it was repaired under warranty. It took a bit of time due to parts shortage, but

Hi Pete, The high voltage is after the transformer, not before. At the antenna connector we have around 50 Ohms. I think it's a combination of current mode and picking the HF up somewhere at the

I don't think 5 or 10W out of an antenna and picked up on the audio line would be anywhere near sufficient to cause any damage to the chip. I was parked up right next to someone running 200W on 11m

Scott, a while back I was testing out an end fed also using the Elecraft T1 and connected to the rig via a couple of metres of coax. As the T1 was going through the tuning cycle on 17m at about 3W I

Many thanks for all of the support. I did have a mono cable on my straight key. Have changed it and the straight key works. Strangely one of the paddles works too since using the correct straight key

Tom I agree with your line of thinking. It seems to me it is a good possibility that the headphone or mic. cable is picking up RF and taking it directly to the audio amp. Larry n0sa
