Re: Implement a uBITX Memory Manager Program
The Arduino delay() function is a blocking function, which means the delay() does not disable interrupts and means that interrupt events can be missed. You can write your own delay routine that does disable interrupts which queues the interrupt(s). Most programmers who are using interrupts write their own delay routine. See: Jack, W8TEE

A quick search of the word "delay(" in the ubitx sources returned
52 hits, with a quite amount of them being 500 msec or more.
Get rid of the blocking delays and the CAT control will work
flawlessly. Been there done that for a project.
Note: you can do a dirty hack and build a fast as
hell non blocking delay of any length routine
breaking the amount of time by smaller chunks and check for serial
commands in the meanwhile, 10 millis worked for me... but this is
a dirty trick, you can also try to reprogram the routines that
depends on delays with a account for millis instead or thinking
out of the box... at the end refactoring will lead to a smaller
firmware that the dirty hack...
Even with interrupt routines (that you don't use) it can be
worked out, they can be changed to work in "flag flip, do next"
instead of "do this code right now" and it will work.

Re: Trouble With Alternate Audio Inputs (BITX40 Module)
I suspect they sent 75 Ohm BNC connectors with the kits. 75 Ohm connectors have a larger center pin. Had same problem and once I replaced mine with the right 50 Ohm type, that problem went away.

I can also recommend the WA2EBY linear - it works great with my BITX40v3 using a 7dB pad. The next linear I'll build is the EB63A from Communication Concepts. It's been confirmed to work with a number of QRP rigs including various BITXs. Like the WA2EBY amp, it has an RF-operated keying relay circuit so requires no radio mods. http://www.communication-concepts.com/eb63a-140w-hf-amplifier/ http://soldersmoke.blogspot.com/2014/11/oh-no-soldersmoke-goes-qro-bills.html If you decide on the WA2EBY amp, I suspect you'll find it to be a beginner-friendly project. It's easy to build and adjust, especially with Leonard, KC0WOX's parts list, source links, and build instructions. His Mouser project list covers all of the parts. While a couple of the specific numbers are obsolete, Mouser has plenty of replacements. When I load the list today, I see that we need an alternative for a 500V mica cap, an SMD cap, and a relay snubber diode. https://www.mouser.com/Passive-Components/Capacitors/Mica-Capacitors/_/N-5g97Z1yzvvqx?P=1z0x6fr&Keyword=1500pf+500v+mica&Ns=Pricing%7c0&FS=True https://www.mouser.com/ProductDetail/KEMET/C1206C470J5GACTU/?qs=%2fha2pyFaduhj4YtAUYl%252b9fuwN6gIhX5Y0mIEIemTc%252bkLaweq9tYXxg%3d%3d The diode can be any 1N4004 or similar.

I had an issue with the BNC connectors that came with my bitx40s. The center conductor was making a poor connection and I too had no output. I replace the BNC connector with a new one and all set now.

I have found that acetone will often soften or dissolve epoxy bonding agents.

Mines in the same bag too I guess?
As tracking says the 12th too! India post time delay seems to be between a month and 8 weeks.. Plus we all ordered at the busy time of December, Xmas season so everything is backlogged. You can bet it's like budget airlines when there is enough room in the hold they fire a bag in there, until then they stop locked in a room at Mumbai Don't panic! We are all in the same boat. 73 Steve

They say the EBY amp puts out 40 watts with a 28v supply. What's the current draw on that?

Re: My µBITX in its new home
Never would have thought alcohol would work for hot glue? I hot glued a knob to a cheap encoder module that I was trying to use a couple years back since the knob was surplus aluminum but no set screws. When I was done I gently heated the knob till glue was soft enough to wiggle off, the knob is worth more than encoder.

I’ll have to try the alcohol next time, I’ve tried acetone before not much luck. Thanks for the idea. James Lawrie

Re: Micro-BITX ... Lost in post ? Possibly
m0icr@...
Mark, 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 http://www.parcelcode.com/Tracking/Track 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. https://www.royalmail.com/track-your-item#/ 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!
