Mine posted same date as yours, tracked to Mumbai 15th as well, still not arrived¡­maybe they¡¯ve become lovers and eloped ;-)¡­seriously I haven¡¯t emailed HF Sigs yet, maybe I should in case a bag of them have gone missing

Re: Micro-BITX ... Lost in post ? Possibly

 

Mark,?

You and I are in an almost identical situation, I live in London UK. Day 31 here.

I ordered my uBitx on 10th December (first-batch order, like yours), my package was also tracked into and *out of* the Mumbai 'Office of Exchange' on 15th December as confirmed at
I haven't chased it with HF Sigs yet but there seems little point unless to arrange for a replacement to be sent but I am now starting to wonder at what point this is the best course of action (see below and the latest from Royal Mail)? The radio was a Christmas present to myself, I knew it was very unlikely to arrive before Christmas but I really did expect it to have arrived by now.?

I have also seen or heard nothing since Mumbai. I too have spoken with the UK Royal Mail and they have no record of the tracking number as issued by India Post and to back this up the tracking number is not recognized as valid on the UK Royal Mail online tracking system.?As far as the UK Royal Mail is concerned my package is not on the UK system and they can not confirm where it is, if indeed it has arrived in the UK at all. That *is* a concern.??

For further confirmation, I have *this morning* spoken with Customer Services at the London Heathrow Worldwide Distribution Centre (HWDC) (Tel UK 0843 548 8217)?via Royal Mail customer services, which is the UK main sorting office for international mail sent by air to the UK, and they are (1) Unable to track my package, (2) Have assured me that they are *not* suffering a major backlog. UK Royal Mail are quite clear - the package has *never* been on their system.?*This afternoon* the advice of the UK Royal Mail parcel tracking team (Tel UK 0345 774 0740), using my India Post tracking number as reference was that: (1) The Parcel should be here by now and that they strongly recommend initiation of what they called a 'postal investigation' which must be started by *the sender* through India Post, and that India Post would then liaise with UK Royal Mail, I was also advised that an investigation can take up to 8 weeks. They also confirmed that they are not aware of any backlog in UK customs (HMRC) clearances at their international handling centre and in fact said that typical handling time was (quote) "5 days or less at the moment *because* of Christmas".

I assume (or more accurately, I fear) that this proposed 'postal investigation' would involve continued delay whilst the package is located and/or any remedial action is taken, ie. a claim for the loss is submitted and then eventually a replacement (back log permitting) is sent? Ouch.

Where does the responsibility now rest to sort this out because from what I have heard from UK Royal Mail today they don't think that this is their problem furthermore I am sure that the solution is no longer about just being patient!

To be clear, in no way is this a personal criticism of Farhan or the excellent innovations and fun he has brought to the amateur radio community, or the fantastic work he continues to do to offer worthwhile employment opportunities to ladies in India, but it is a genuine concern from a customer (and Bitx enthusiast) who simply wants to enjoy their new radio but who is now starting to fear that their package could be lost/taken and that it's going to be months before a uBitx arrives.

Of course it could arrive tomorrow despite what the UK Royal Mail have told me today ... stranger things have happened!

The software for automatic link establishment also turns out show you a spectrum analyzer in bar chart form. ?Just by watching the waterfall in FL DGI or other software you probably got a intuitive understanding as well.

Dave,

Thanks. I dug into the software and? found out how to get into setup. OK now.

r.e. the BFO - as you know, the receiver on a ubitx is a 12 MHz fixed-frequency receiver. USB/LSB switching is done in the previous mixing stages. Using band-noise as a wideband signal source, if one views the ubitx audio output on an audio spectrum analyzer, it should be quite easy to set the BFO frequency to a desirable setting.

On Linux there is a great open-source audio spectrum analyzer called JAAA. On garden-varitey USB sound cards you can see at least an 80 db range. I will use JAAA to view the ubitx audio spectrum and set the BFO accordingly. Then, in the ubitx.ino code, one can tweak the SECOND_OSC_USB and SECOND_OSC_LSB constant definitions to achieve balance when switching sidebands.

I am sure there are useful audio spectrum analyzer programs for Windows and Mac, which would work equally well.

That is my plan for today; I will travel to my shop and will let you know how it works out.

Re: Amplifier Kit?

 

Seems acceptable to twiddle RV1 (or some sort of mike audio gain) when switching bands, given the $120 price.?
Though we need a convenient way to indicate how far to twiddle.

Adding negative feedback as per post 38817 to the existing uBitx final,
then driving that reduced but consistent output into something like the WA2EBY is also a good option.

Re: Micro-BITX ... Lost in post ? Possibly

 

I ordered my uBITX on December 10th and it still shows "in Transit" (to VE3). ?Note that on the reply email from PAYPAL
says "Shipping: India post 3-4 weeks (with partial tracking)", so there is no guarantee of being able to track it all the way.

Mark, ?I wouldn't give up hope just yet. It is not long overdue?and this is a busy time of the year for shipping.
I would give it a few more weeks before I start worrying.

I guess it would be more like a 4P switch, 2 for the input pads and 2 for the LPFs.
You could also use relays. The switch would just turn on the appropriate relays.

Yes, it makes the part count increase, but it is only a few more resistors.

Re: Implement a uBITX Memory Manager Program

 

If you are wondering about RTOS, I think RTOS should be monitoring most interrupts as much as possible.

However, the questioner is curious about the timeout.?Timeouts will only occur in the original source of uBITX.
Suppose that you press the menu button once and wait for the next button in the while statement.
Let wsjt-x transmit the protocol that reads the frequency once every 500ms, and if there is no response, it displays an error and disconnects.
When the user presses the button to select the menu and wonders whether to move the band or change the CW tone, 500ms flows and wsjt-x displays an error and disconnects.

This is a problem that can be easily solved using an interrupt or an RTOS.?
For this reason I talked about the interrupt and the RTOS.?If you are wondering about RTOS, please feel free to ask.
I will explain in detail what I know.
