Agree with Allison. The extra length of the plastic gets snaggy when putting a radio in a bag. If you look at a QCX the long BNC is ridiculous. So I ask Allison if the shorter BNC is reliable.

Well actually, I only object to the length of the current BNC. I was trying to match the "MountainTopper" and a short BNC is used on that I think. So I would like to see Han's comment on reducing the

SMA for size. BNC for durability and less fiddly when up on a hill with cold hands. Note some of the PCB edge mount BNC may provide a lower profile. Allison ------------------------------- Please

Worn out dozens over the years. I'd add 500 is optimistic. Failure mode is center socket looses flex and fails. Second most common the center pin of cable breaks loose from the internal wire. Best

We should live so long!

Regardless of the connector used, I would likely not mount it on the PCB even if the board provides for it. Off-board mounting, to me, gives me more flexibility in the case I might use. My problem is

James, if you are getting that much power out, then everything else is probably good, so OK to play with the lowpass filter. Ron

Hi, I have a nanoVNA with SMA fittings. The early deterioration most likely affects their performance in the microwaves. I use mine at HF and may use it some day a time or two on two meters but

Please, no. Those give me nightmares. Too many cases of them either not staying in or refusing to come out.

What about RCA connectors?

Jay, did you check voltages on IC5, 6 and 7 yet? Are you seeing the nominal 2.5 volts at pins 1,2,3,5,6 & 7 of all three of those? Ron

Supporting both SMA and BNC footprints makes a lot of sense to me. Use right angle, PCB mount connectors. Not the edge mount SMA's like those used on the nano. I'd expect that having the connectors

I admit I voted for SMA, mainly on the basis of my experience with those threaded plastic BNC connectors, UGH! I'm more in favor of a bulkhead mounted connector with a jumper to the board. If the the

I had the same problem show up a couple months ago. I ended up taking it apart and liberally applying WD-40 to where the turning knob comes in. Works better than before now, though initially I noticed

Hans, 9.1 cuin ....with a 2x16 display, and DIP ATMega328.....WOW. .....with all the SMT premounted, that's cool. I think 92mm x 25mm x 63mm is one of the "standard" aluminum clamshell enclosures like

I'm not pro or con on this but it is interesting to note that Elecraft uses SMA connectors on their 2/4 meter transverter for the KX3. I'm well past 50 cycles with no trouble on mine but now

BNC connectors without the plastic housing exist. I have a mini oscilloscope, a DSO138, that has one. Here are links to

I would say prefer board mount BNC .....but find one which does not have the plastic housing (I believe they have those). If you are really an industrious builder with all 5 fingers on each hand, cut

True, but Tyco Electronics also specifies only 50 cycles for their gold plated center pin BNC connectors. https://docs.rs-online.com/616e/0900766b81409ff0.pdf 73 de LA9XKA - Per

SMA connectors have a limited life span measured in only 100's of mating cycles. Check the data sheets for Ampehnol, Pasternack, (etc) parts. The inexpensive SMA's from Asia quite likely are even less
