This looks similar (with the same specifications) to the frequency counter that I have been using for a few years, and I paid a similar amount of $$$ for it off e-bay. I have found it a good piece of kit for general amateur use. The stability of my unit is good and within specification - I reference...

Hi, The kit seems to be of good quality, it can also be purchased of Banggood for AU$22.60 including shipping. Refer: http://www.banggood.com/DIY-45W-SSB-HF-Linear-Power-Amplifier-Amateur-Radio-Transceiver-Shortwave-Radio-Development-Board-Kit-p-1018834.html A review on the banggood site states: &qu...

Will aim to be on air.

Hi Nev,
Try the following:

It may point you in the right direction.

Hi Wayne, Perhaps .... I expect that frequency stability would still be an issue, but Gunn Diode based transceivers would probably be less stable. The unit looks like a doppler motion sensor. These are available off e-bay real cheap. You may find the following link of interest: http://www.limpkin.fr...

Hi Bob,
Thanks for the feedback. I seem to be getting de-codes that do not always end up on the map?
I suspect that my firewall is being a problem.

Hi Andy,
Thank you, have upgraded to the modified version. Nothing heard so far.

Hi Andy,

I am listening on 14.095.60, just want to confirm the RX on WSJT-X should be 1800 as shown.

I have also had and 857D in a 4wd mobile situation (Pajero NL) since 2005. Similarly it has performed flawlessly - no display issues.
I use a panel extension kit, with the main radio boy located under the driver's seat. A brilliant radio!!!

I have one of these off e-bay: http://www.ebay.com.au/itm/Handheld-Capacitance-Inductance-L-C-Meter-LCR-LC200A-Multimeter-Electric-Bridge-/221270029038?pt=LH_DefaultDomain_15&hash=item3384b8b2ee It appears to do what it claims, and will set you back around $45 posted. Measuring SMD inductors may...

Hi Adam, The updated page is fantastic!!! I like the path profile addition. :D The feature to report S/N ratio for JT(x) was there all along, I just had not noticed it - thanks for pointing it out. See http://physics.princeton.edu/pulsar/k1jt/wsjt.html for info on the WJST modes : JTMS, FSK441 for m...

Hi Adam,
The changes look great. Just a suggestion, with the addition of JT4 perhaps an additional column for Digital Signal reports that are specified as signal-to-noise ratio (S/N) in dB.
RST is good for CW, but we give a more quantitative measure with the digital modes.

Hi Peter,
Thanks for the info - working great using JT4F.

A big thank you to the Brisbane VHF crew. I am hearing the VK4RBB 70cm and 23cm beacons stronger than ever.

I like the JT4 addition . A decode off 70cm is attached, still having difficulty decoding 23cm. Perhaps it is not JT4D???

Hi Adam, A good question, but I do not think so. PcDuino Nano V3.0 - All Winner A20 SoC (Dual Core) Raspberry Pi 2 Model B - 900MHz quad-core ARM Cortex-A7 CPU Both have 1 Gb RAM and run various flavours of Linux, but there is extra $ for a lower spec CPU if you go down the PcDuino path. Yes, it is ...

Scott - I will aim to be there, family commitments permitting. Shane - A real rough path to you from my QTH, some 818.161 Km over mountains :shifty: Rex - I should be able to work you. Have worked up that way previously, but with an 18dBi grid I find that I am am constantly on the rotator looking fo...

Thanks for sharing this. The 3.5", 480x320 high resolution Intelligent Display Module looks great, but the price is a little high on the URL you have listed. There seem to be lower cost options on eBay, such as "SainSmart 5" 5 TFT LCD Touch Panel (Resolution 800x400) + TFT LCD Shield ...

I aim to be around. As usual the rotator will be doing overtime as I swing the antenna around

Hi,
I aim to be there. Hopefully all the Xmas shopping will be done by then, or at least the XYL will have had enough of the shops!!!

I use a WESTERN UNION LEGLESS 2-A TELEGRAPH KEY & SOUNDER on my TS-2000X. It is well over 100 years old from the 1800's, works well, and looks neat :D I do not have the sounder connected, just the key. But the sounder does work :-) I suggest that the key thing is to find something that you like ...
