FET 2N4091 metal case JFET or equivalent. Must be metal case for freq stab.? Bipolars : MPSH 10 or better use? the? BSX-20 which has a FT of 500 Mhz and very low input capacitance c/w 2n2222.? and get rid of the silly 9v regulator chain use an LM 78L09 regulator chip or similar. TEF

My QTH is the east coast of Ireland, so will be very lucky to receive the 5, 10Mhz WWV?transmissions, for Zero Beat calibration, given the propagation conditions lately.
I'll have to tune to a local AM broadcast channel.
Thanks for the suggestion anyway.

I am not interested in purchase but if you do sell and want to stay in the hobby , without much more money you could buy a CS? SSB transceiver from?

He has an agent in Nth America.? Unless he forces you to go direct to the US agent? then you can purchase at USD 120, 10 shipping and about $25 assly charge as I am guessing you would not be willing to assemble and test because of risk of it not working and then your getting stuck.? ?THIS is a MONO band transmitter and it is blind. you know you are in band because it it DDS controlled , ie a local oscillator from a quartz time based? but unless you build yourself a marker generator you don't know where exactly you are (you can however put a calibration cheat around the dial). These use a generic IRF 530 Mosfet as the final? so if the final blows you can replace it for around $1.50 or so. It is theoretically possible to convert this transceiver so it can do CW as well though it would give the internal relays a? bit of a hammering. You may never want CW.? ?The other option is another monobander from OzQRP? which is Run by Leon in Canberra area.? He sells a sort of Bitx .. all anlogue and you can either make your own VFO or use his CVS I think he calls it.. which sells for USD 45 equivalent and is a very slick looking unit with a multiline illuminated pixel display doodad.? If you want to roll your own VFO you can use one of? A Farhan's designs .. I will attach a rather sleek one .. you can get the FET from either Rockby electronics in Melbourne? or from Dan's kits and parts in Mo in US.? There are several sources for air variables NOS on the web INcluding ONe I saw in the US for less than $10. Contact me directly for details. What you could do is set yourself the target of getting a VFO going and if that fails go for a? built up transceiver and if you pass then you can buy either? of the above transceivers as a kit...with the OzQRP unit you already have an agricultural VFO going and you need only buy the base transmitter kit sans vfo.? Eventually you will get fed up with the analogue vfo and will buy the CVS and integrate that in? your box. The Farhan design shown needs to be rejigged to tune 2.8 to 3 Mhz so it produces 7 to 7.2 Mhz when subtracted from the IF frequency of 10 Mhz that Ozqrp use. If you treated your tecnician licence study seriously you can do those calcs. It really needs the coil rebuilt as a T50-6 toroid. You can most likely get one of those as a one off from Fred at Far circuits, or you can get it and a few other toroids and semis as a bunch from? the Toroid King in Florida.? The Farhan schematic has a few idiocies. Firstly there is a resistor with a missing value. Anything from 50 to 100 R will work . THere is an electrolytic wit no value , use 10uF and the tapping point on the coil is not show, use 1/3 turns up from the grounded end.? If you are to do any experimentation at all you will need a frequency counter and I have just heard of one that? as? bare unit sounds plausible. 6 digits? eg 14 020 1 Mhz ie down to the 100s of hertz resolution $ 13 USD. Obviously ex PRC.? It will be an extension of the Wolf Buscher design. ..almost for sure.? have a look at ? ? ?site and good luck with what you try to do. Subs. BFW11 Unavailable . Use 2N xxxx I am dead tired and might muck up and lose this post so contract me direct for trans and FET subs if you are going lto built the VFO.

Don't do the Tune Up Calibration unless you absolutely have to.

BITX QSO Afternoon/Evening, Sunday, August 5, 3PM & 7PM Local Time, 7277 kHz in North America, 7177 kHz elsewhere.

Join us as we make contacts with our BitX-40s or uBitXs or anything else on 7.277 MHz in 40 meters!

This is a worldwide event for BitX40 (and other QRP)?stations starting at 3PM and 7pm in each time zone. To participate, call CQ BitX on Sunday, starting at?3PM and/or 7PM?your local time. The BitX QSO Night continues through the evening and conditions usually improve after sunset, so it is worthwhile to participate later in the evening.

Suggested Best Operating Practices:

Work at QRP power levels unless conditions require more power.
Call and listen for CQ BITX on the hour and every quarter hour.
It is helpful if you call CQ BITX with your callsign, name and location.?
Repeat your callsign a number of times during your CQ BITX and during QSO's.
Start a QSO by confirming the callsign, location, name and signal report of the other operator.
Say the callsign, name and location of the other operator so others can hear.
If the frequency is busy, avoid long conversations.
After your initial QSO is complete, ask if there are any other stations who would like to contact.

Report your QSO's, discuss propagation, noise, signal reports, audio reports, antenna type, etc. in this thread.

This is an undirected, scheduled event.? The BITX QSO Night relies on you to call CQ BITX to initiate contacts with other stations, so warm up that final and transmit a few calls on Sunday evening.? Talk to you then!

If you whois gapantenna.com you'll find they have 3 nameservers set up

It's dead Jim.

Fortunately the other two nameservers work

gapantenna.com. 1922 IN A 199.189.195.12

My advice (unless you are comfy with making temporary local host changes)
is to restart the browser and hope it catches one of the two working NS

There are reports from 3 different EU countries that the site doesn't resolve there.
Using a VPN to provide a point of presence within the US does.....
This would indicate it's the source site not the destination(s) that is experiencing difficulties, else there are EU DNS sanctions being applied? :-P

Go for it, Nick! It seems that there are quite a few looking for some through-hole kits.
Don't forget, this circuit also works the same on BITX40s as well.

One thing you can try is to change your DNS server configuration. You are very likely using your orovider’s DNS servers. You can change that to e.g. OpenDNS or Google:

hi

do i need to hack the receiver input filter

terry

Terry,
The latest Raduino sketch v1.28 provides this feature:

Prevention of out-of-band transmissions

The software restricts transmission to the 40m ham band allocation. By default this is ITU region 2 (Americas: 7000-7300 kHz). If you are located in a different ITU region, uncomment ONE of the lines 44-47 depending on your location, and recompile.

If the is installed, out-of-band TX will be disabled, but RX is still possible outside the band. If the is NOT installed, both TX as well as RX will be disabled outside the band.

just a bit more about my hacking requirements
what i would really like is a general coverage receiver (like the ubitx) but leave the tx to 40 m only
presumably this means a hack to the rx input filter and a hack to the sketch

any ideas

Thanks guys, Don't think it has anything to do with the EU privacy issues also cleared out all cookies etc and no change.
It looks like a DNS issue and somewhere in the chain from the masters an update error is occurring.

Bob I know these are non components boards? but I suspect they use the 7822 audio amp. THere was a bleat that some? Chino TDAs were failing. If so I know of two sources for NOS? replacements one out of Oz and one in USA. .. ad we are not talking crusty old Dan in Montana. Email? TEF if this is the case.
