Re: Availability of TX-500
Get them on the phone. Something isn't right. My wait was three weeks from order to arrival. Far sooner than expected.? The deletion from the orders is scary. Get them to figure it out so you get back in the line.? On Mon, Jun 7, 2021, 4:58 PM <georgi.gatin@...> wrote: I am out of lick. Ordered on May 10, payment processed May 12. No tracking. And even worse - it has disappeared from my "web orders". What is going on, HRO?? |

Re: CW KEY
That is exactly what I am thinking. I would confirm continuity with a meter and make certain the cable checks out.? On Fri, Jun 4, 2021, 1:59 PM John Dziedziejko <dziedziejkoj@...> wrote:

Re: CW KEY
Hi John - Are you using the same cable for all the keys?? Just trying to think through the troubleshooting.? 73, Steve de W0ARK On Fri, Jun 4, 2021, 12:34 PM John Dziedziejko <dziedziejkoj@...> wrote:

Hi Everyone, Is there a setting to turn the keyer on or are all the connectors on my iambic keys wired incorrectly?

Re: Setting Drive Levels and Monitoring ALC
It's in the TX-500 manual, Menu Functions, Item 23, TX Metr.? Of course Tim's instructions provide more detail.? Hopefully, over time the TX-500 manual be updated to provide greater detail, maybe even an Index in the back of the manual.? A word search does find all the instances where 'alc' is found in the manual. 73, Henry - K4TMC On Fri, Jun 4, 2021 at 9:23 AM <tim@...> wrote:

Re: Setting Drive Levels and Monitoring ALC
To monitor your ALC level
Use the bottom left or right most button under the screen to scroll through the menu options till you see 'METR' in the top right of the screen.
push the button for 'METR' (top left most button above the screen)
spin the vfo left and right till you see ALC on the bottom / middle of the screen.
transmit and the meter bar should display the ALC response to your signal, adjust computer speaker volume as needed
hope that helps!

Re: Setting Drive Levels and Monitoring ALC
Lab599 wrote this in a FB response. "
The ALC in the Discovery TX-500 transceiver is essentially protection against high SWR and is configured to prevent the failure of the output stage. At high SWR, the ALC will lower the output power to a level that is safe for the transceiver. The ALC parameters are selected by engineers and do not require additional adjustment by the user.
The ALC graphic scale allows you to visually assess the decrease in output power, which in turn indicates a high SWR and, accordingly, that your setup as a whole is not optimally tuned.
There is no external control of the ALC in the TX-500.

Re: Feature request discussion - coverage of 450-500 kHz RECEIVE ONLY - e-mail to support@ was not positively received
Dave, There was an earlier issue with the TX capability on all frequencies within the 60M band.? Although I am not a user of that band, I believe they were able to fix that in firmware update 1.04.07 back in January of this year.? Maybe others can confirm that 60M TX freq capability is now fixed. If they were able to fix that via firmware, I would think what you are requesting is feasible, unless there is an internal hardware bandpass filter circuit that limits sensitivity significantly below 500 kHz. 73, Henry - K4TMC On Thu, Jun 3, 2021 at 12:09 PM David Feldman via <wb0gaz=[email protected]> wrote: I would like to use my TX500 as receiver for 630M band signals (around 470 kHz), however, the current band assignments (for receive) cut off at 500 kHz.

Feature request discussion - coverage of 450-500 kHz RECEIVE ONLY - e-mail to support@ was not positively received
I would like to use my TX500 as receiver for 630M band signals (around 470 kHz), however, the current band assignments (for receive) cut off at 500 kHz. This would of course require appropriate amount of gain in the receive path and such, but given that the radio does receive in US AM broadcast band, it seems possible to me from an RF (if not firmware) point of view.
I e-mailed support@... this question, and Ogdep replied: "Hello Dave, The band range is set according to the requirements for amateur radio equipment for the respective region (US / EU). Compliance with the region is set during production at the factory. Unfortunately, we cannot remotely change the transceiver region and band range accordingly. 73, Lab599 team" I am not familiar with US regulations that would dictate RECEIVE capability (at least in the US I think portions of the old analog cell band are precluded, but I've heard of nothing else.) I'm not familiar with any such regulations in EU or elsewhere but I imagine they exist. If the band limits are in firmware that can be updated, I should think that this request would be technically possible to accommodate at some level (if not precluded by policy decision). If the band limits are stored elsewhere, then this suggests that no future changes to band limits (to accommodate some future regulatory change, such as further revision to band limits), nor changing band limits for a radio that is individually shipped internationally (where other band limits would exist), could be accommodated. This seems like it would be a future concern. At this point, I am just curious if there is more insight possible, and a follow-up question to Ogdep has not been answered, at least at this point. Thanks very much for any thoughts, Dave |
New firmware feature - CW Pitch Matching Indicator
The description in the manual ("CW side tone pitch matching indicator") is a bit confusing, sorry. In CW mode, when your receiver is exactly on the sender¡¯s frequency, the TX500 will display a small diamond shape on the screen. Similar to the ¡®spot¡¯ feature on other radios. The diamond may not appear if the sender's signal is weak.
For those wanting a bit more information about CW frequency offset, zero-beating and side tone pitch, here is a good explanation thanks to Cliff at QRP School. https://youtu.be/8Dxx-N2CVPI |
