Session text follows


20:44:06> *** You are now talking in channel: "OpenHPSDR"

20:59:20> "John - AJ6BC": Hawks/Kings - Good Luck to both!

21:09:05> "Greg ZL3IX": Has anyone tried Alex VE3NEA's new VNA? 
  I plan to try it this weekend

21:12:58> "Rick - VE3MM": APF!  Awesome Warren.......

21:15:50> "John - AJ6BC": Sure Bill - NP!

21:16:16> "Bill - KD5TFD": And I forgot to say "Go Rangers!" 
(hockey)

21:16:26> "John - AJ6BC": Greg - Vector Network Analyzer?

21:16:48> "John - AJ6BC": Yeah - great game yesterday - 
Canadiens vs. Rangers.

21:17:08> "Greg ZL3IX": rr John.  Alex has written a new one for 
Hermes

21:17:17> "Bill - KD5TFD": Now have to hope Chi/LA goes 7, w/ 
triple OT

21:17:58> "John - AJ6BC": Exactly Bill.

21:19:25> "Rick - VE3MM": Hockey is over for me with the loss 
last night. Boo

21:20:03> "John - AJ6BC": Impressed with that Canadiens goalie.

21:20:11> "Bill - KD5TFD": You follow the Totonto Marliies ... 
they're playing the Texas Stars in the West Conf finals in the AHL

21:20:57> "Bill - KD5TFD": ya quite a goalie

21:21:29> "Rick - VE3MM": The Habs goalie really did keep them 
in the hunt.  They would have been out playing golf a lot 
earlier if it wasn't for him

21:21:42> "Greg ZL3IX": Thanks for the answers, guys

21:21:55> "John - AJ6BC": 0-1 - can't get much closer than that. 
  Some of those saves in the 2nd period were unbelievable.

21:22:27> "Mike - AA8K": I really like the VNA.  Told me lots 
about my antennae, and discovered problems in some RF filters.

21:22:41> "Rick - VE3MM": Bill, I didn't now the Marlies were in 
the AHL semis.  Thanks, I'll take a look at the series.

21:24:30> "Greg ZL3IX": I have been using the N2PK VNA for about 
9 years, but the dynamic range on Transmission should be better 
than N2PK, with a
well calibrated Hermes

21:24:39> "Bill - KD5TFD": looks like game 6 of that series will 
be Monday night here  - might be time to take in an ahl game ... 
they play one town
over from me

21:25:10> "John - AJ6BC": Have a question for the hardware guys 
- one the connectors - SMA vs. MCX?  The footprints are the 
same.  I don't think I will put down MMCX.  Also - TH vs. SMD. 
I am using mostly TH.  Any bad luck with the SMD SMA?

21:25:19> "Dave WW2R": alex version beats the n2pk i borrowed

21:25:26> "Rick - VE3MM": Sounds like a great opportunity to see 
some fabulous hockey live

21:25:28> "Greg ZL3IX": r dave

21:26:00> "John - AJ6BC": Kings and Hawks on now - NBC SN.  1st 
Period.

21:26:19> "Greg ZL3IX": John the MCX is a great connector. 
Being push fit, it's very convenient, and is also reliable - 
used by the military.

21:26:25> "Dave WW2R": alex vna worked fine at 475khz

21:26:36> "Scotty - WA2DFI": I would not use SMD SMA connectors 
- we used them on the HF2 and broke several of them off before 
we got smart ans switched to TH

21:26:59> "John - AJ6BC": Thanks Greg and Scotty.

21:27:20> "Mike - AA8K": MCX:  what is the number of insertion 
repetitions?

21:27:46> "John - AJ6BC": Let me see if I can find that.

21:27:48> "Dave WW2R": the micro rf connector that came on my 
navspark gps is rated 6 connections/disconnections

21:27:58> "Bill - KD5TFD": 6?

21:28:04> "John - AJ6BC": 6????

21:28:09> "Mike - AA8K": SMA is 20

21:28:11> "John - AJ6BC": 5..4..3..2...1...

21:28:51> "Dave WW2R": it the same one that Elecraft have put on 
the kx3 internal 2m xverter, they recommend a similar number of 
connects

21:29:03> "Greg ZL3IX": MCX will do at least 20, I would think

21:29:31> "Bill - KD5TFD": I don't think surf mount connectors 
are a good think ... seen many many broken micro usb connectors 
on gizmos

21:29:33> "Dave WW2R": mcx is abt twice the size of this one

21:30:06> "John - AJ6BC": MMCX probably.

21:30:19> "John - AJ6BC": Linx says 500 'matings' for MCX.

21:30:33> "Greg ZL3IX": Doesn't surprise me

21:31:17> "John - AJ6BC": For SMA, they say 500 'cycles' min.

21:31:33> "John - AJ6BC": I have used SMA a lot - 20 is substandard.

21:31:57> "Mike - AA8K": Ah, thanks John.  I feel better about 
Hermes.  I was reading a spec and it said 20.  Must have been MIL

21:32:02> "John - AJ6BC": In some RF labs I have worked in - 
easily exceeded 100's of mating cycles with no problem w/SMA.

21:32:17> "Greg ZL3IX": In a previous life, we used MCX on an 
airborne military radio, and it also passed 8g random vibration 
for 2 hours in each of
3 axes

21:32:45> "John - AJ6BC": RU sure they didn't mean insertion 
loss vs. 'insertions'?

21:34:10> "Greg ZL3IX": Agreed Bill

21:37:11> "Greg ZL3IX": 73 all

21:37:21> "Scotty - WA2DFI": 73 greg

21:37:30> "Bill - KD5TFD": 73

21:37:49> "John - AJ6BC": 73's Greg - but he's already gone.

21:38:02> "John - AJ6BC": Linx - MMCX - 500 'cycles' also.

21:38:52> "John - AJ6BC": Linx - Type N - 500 cycles also.

21:39:44> "John - AJ6BC": Well, guys, got an appt. with the BBQ. 
  See you next week.  73's.

21:39:48> "Mike - AA8K": [OT] is anyone running OpenSSH without 
fixed IP addresses and no password?

21:40:06> "Scotty - WA2DFI": 73 John

21:40:13> "John - AJ6BC": 73's.

21:40:25> "Ken N9VV": Melton successfully ported WDSP into his 
demo "wHPSDR" code on an Nvidia Jetson TK1 development board.

21:40:41> "Bill - KD5TFD": no password == certs for login?

21:41:00> "Mike - AA8K": SSH, yes, certs

21:41:18> "Bill - KD5TFD": Yeah ... no problem to do it w/o a 
fixed ip

21:41:49> "Mike - AA8K": SSH thanks Bill, I'll do more Googling.

21:42:12> "Bill - KD5TFD": easy to setup  ... generate  a key 
for yourself

21:42:25> "Bill - KD5TFD": private side goes on client side

21:42:44> "Bill - KD5TFD": on servers you want to access you put 
public side in authorized_hosts ssh file

21:42:56> "Bill - KD5TFD": and off you go

21:43:32> "Mike - AA8K": SSH  I can generate the key, but when I 
try to copy the public one, Authenticity of Host can't be 
established.  Every thing I've looked up today says to use 
static IP.

21:44:05> "Bill - KD5TFD": hmm .. on 1st connect you get warning 
on key not being in known_hosts

21:44:18> "Mike - AA8K": Static IP is like going back to using 
interrupt jumpers on boards.

21:53:34> "Ken N9VV": GN/GB de Ken

22:04:44> "Warren - NR0V": 73 all --- time to check on dinner here.

22:04:51> "Bill - KD5TFD": 73

22:07:15> "Bill - KD5TFD": 73 all -- of to find some dinner.
