Default Instrument Case For Transceiver

I've looked at the aluminium boxes which look great for most
projects but I want something a bit stronger and professional
looking for the transceiver. Maplin also sell the Hammond range of
enclosures but their biggest is too small. Since posting I have
found a bigger range of the same style at Rapid Electronics and I
may go for one of these.

I'm pretty excited about building the BITX20A, my plan is to use an
LCD display using a 10 turn pot/varicap diode instead of a tuning
cap and I aim to bring the cost in at under £100.

==========================
Charlie , When replacing a variable aircap by a 10turn potmeter +
varicap , I would suggest you pay much attention to the stabilised
voltage feeding the potmeter/varicap ,to ensure acceptable frequency
stability


Better yet, the counter already has 95 percent of what's required for a Huff
n Puff stabilizer. Add that and the rig will stay put for months.

Charlie, my boxes are the same external dimensions as that 1455T2201.
