People need to try and work with SMD parts...it IS easier than you think. I also use the approach below, but use tweezers to hold the part in place while soldering. I find: the the left-most pair

SMD is easy.? So much better than through hole. I put solder on one pad.? Drop the part, push it around with an exacto knife. Hold down with a finger or (finger nail for small 0805 parts). Solder

Looks like a useful technique for SOIC parts, as shown in the picture. There are many kits that use a few SMD ICs of that size along with mostly through-hole components. The Softrock series is a good

My first search of Mouser showed the 22MHz, 26MHz, and 29MHz not available. Second try found them all. Bob Macklin Seattle, Wa. --- New Outlook Express and Windows Live Mail replacement - get it here:

An update to the above, the 22 MHz is in a HC-49US short case at $0.47 per unit and in stock. Digikey might also have all of them in the larger case, but I haven't checked. 72/73, Jim, K8IQY > > >

Chuck, The only way I know to beat USPS cost is to sign up with someone like Stamps.com for $17.99 per month. That will get you a 40% discount on Priority mail shipping. I think at one time you needed

All of the above crystals appear to be in stock at Mouser in HC49 /HC49U packages (large case) in the range of $0.44 to $0.79 in single quantity.? So the premix crystals are not an issue. 72, Jim,

All we need is one more mode.? Sample for 1sec and display, via scrolling or whatever, the results down to 1Hz. I agree about the Guys dial kit.? I bought a number of them and use them. They are

that is one I did not find, here are a few others including DL4YHF web site: https://www.qsl.net/dl4yhf/freq_counter/freq_counter.html#firmware_download

Google translate may help. I use it frequently on non-english web pages even to the point of being able read German, French, and Russian radio forums. cheers, Graham ve3gtc

Mouser has all but the 22,26, and29 DigiKey has the 22 and 26.

John, As I [perfunctorily] read the manual and schematic, the Sierra requires 7 matched 4.915 MHz crystals for the main board and 1 each of the following for the band modules: RF Crystal PMO

Consider using a DDS in their place I'm looking at using a microcontroller for computer interface (CAT) and replacing the VFO with a DDS. I'm working on doing that to a NorCal40 right now. Bob Macklin

One thing to consider if one is to build the band modules is that some of the crystals at the needed frequencies will be tough and or expensive to get. 73 - john - n0hj

Sehr gut in den Sierra Boards, mein Freund. Aber die bestellseite ist auf deutsch und was von uns die nicht "habla" machen? Wie bestellen wir? (Very good on the Sierra boards, my friend. But the order

My 2 cents worth on "pullability" of crystals... My experience is that full size 49 xtals offer a larger freq span than the short stuff. Another thing...Over many years, I have seen multiple xtals in

A discussion on the differences came up somewhere not long ago. I had made some measurements while re-doing the filter in my ATS-3 and also when using the "short" crystals in another ("measurement

I stand corrected.? I did a quick search and found that the DL4YHF frequency counter code is open source. https://github.com/TheHWcave/PIC-freq.counter-modification/blob/master/counter_TheHWcave.asm

Project is progressing, but I hit a bump in the road or I ran over something.? :-) First.? Because I wanted to try the higher frequency LO experiment for the NC40A for changing IF to 9MHz and for
