Well, I will have to miss the first one.  Our HAM club meets the third Saturday morning at 0900.
With COVID-19, we are meeting on the Emporia repeater. 146.985.

Next time. Every Saturday on this N-75 group or once a month?

Rex thanks for the tip on this! I hopped on 3730 this morning and heard quite a few fellows, you were just a hair below my noise level with QSB but could make you out about half the time.

Regarding the receiver side, I’ve noticed mine is very sensitive also. Really enjoying the new rig.

Re: Suspect Parts

nm0s_qrp <ai9e_qrp@...>
 

The tolerance for these ceramic disk capacitors is -20%, +80%, so  50% high is within their spec.  These parts are applied in circuit functions where their value, dissipation, and leakage are not critical.  Unless a component s is faulty, like your experience with C9, the parts supplied with the kit are entirely satisfactory for their intended use.  
As far as counterfeit semiconductors go, the 2N3019 transistors used in the Ozark Patrol were, until recently, old stock from 20+ year old inventory, and not suspect.  Since that supply has dried up, we now use parts obtained from a reputable supplier.
Speaking from personal experience, and having obtained a LOT of components from different sources, the biggest problem with counterfeit parts so far encountered were the 2N7000 transistors purchased for the Cricket kit.  The first batch of 'no-name' parts purchased proved to meet all published specs, but had far lower RF gain than parts from ON Semi or ST.  But, RF gain is NOT a specified parameter for these parts, so the still met 'spec', but were unusable for the kit.  So, I have a box of a couple thousand of them waiting for an application where RF gain is not critical.

Re: Suspect Parts

Jerome Wysocki
 

Curt, please keep us posted on your progress with the Ozark Patrol receiver when finished. I checked all resistors before using them here and all were ok. I have problems with regeneration being way too unstable, frequently on this receiver. I made a post several months earlier on this topic, but got no responses. Maybe I have a similar problem with bad caps.

If anyone is interested, I can discuss this topic in a new thread. I've made some notable progress on my problem, and I do believe the problem is fixable.

Re: Suspect Parts

Curt
 

More experiences with problematic parts.

Building the Ozark Patrol yesterday, three of the caps in the kit (C2, C8, and C9) are obviously and easily recognized from you know where..  I always test these and as expected C2 & C8 were about 50% high of marked value with discharge ten times my stock.  C9 was open.  As usual, tossed them in waste and replaced with my own stock.  If they had tested nominally good, not sure if could trust the reliability.

 

Had the same issue with the .01 and .1 caps in the Hilltopper kit, and single-band transceiver kit from another vendor.  Not all were bad but enough to have no confidence in the reliability of the finished kit using the supplied parts.  Once again replaced all with my own stock.  That has become my default approach to these cheapest of parts.

Active components identified with transistor and Fet numbers must be tested too.  I have encountered "Fets" that were audio transistors, "RF" transistors that were actually AF or non-functioning devices.  Years ago I assumed that parts identified as new parts were as labeled and functional.  Never tested new parts.  Now I test everything I can before installing it.  So far haven't been bitten by a counterfeit IC, but they are surely out there waiting.

Hi all,

 

I built my Nouveau 75A last week and find the receiver very sensitive. My output power is around 3 watts at 3.705 MHZ and 2 watts at 3.880 MHZ. In Ohio there are stations on 3.875, 3.880 and 3.885 in the evening which sometime cause some interference when I am on 3.880 MHZ. I connected the 75A to my SB220 and use a foot switch and get between 70 and 100 watts output. I got into the Mighty Elmac net on Wednesday.

Hi John -  I have not had a sensitivity problem and two other Nouveau 75A owners here in Minnesota that I regularly talk with report that the sensitivity is good on their units as well.  Have not observed this to be a problem at all.  We have a morning group on 3730 KHz each day and sometimes when the band is down an amplifier after the Nouveau 75A really helps to make the QSOs sollid Q5 copy.

I posted this to the N75 sub group but I'm not sure who might get it there so I will post here as well just in case.

Regarding a PTT solution for my Nouveau so that it will key an external amplifier please refer to the attached schematic and photos.  A relay works fine to key the external amplifier because the Nouveau has an exceptionally long delay after keying the mic circuit before it begins generating RF.  The relay gives additional isolation without any amplifier hot switching even with the extra time for the isolation relay to close.  This works well with my AL-811H and my RF2K+.  The RF2K+ will generate legal limit AM with the 5 watt Nouveau drive.

Thanks to David Cripe NM0S for help with this.
